NUCLEAR REGULATORY COMMISSION
Biweekly Notice; Applications and Amendments to Facility
Operating Licenses Involving No Significant Hazards Considerations
I. Background
Pursuant to Pub. L. 97-415, the U.S. Nuclear Regulatory Commission
(the Commission or NRC staff) is publishing this regular biweekly
notice. Public Law 97-415 revised section 189 of the Atomic Energy Act
of 1954, as amended (the Act), to require the Commission to publish
notice of any amendments issued, or proposed to be issued, under a new
provision of section 189 of the Act. This provision grants the
Commission the authority to issue and make immediately effective any
amendment to an operating license upon a determination by the
Commission that such amendment involves no significant hazards
consideration, notwithstanding the pendency before the Commission of a
request for a hearing from any person.
This biweekly notice includes all notices of amendments issued, or
proposed to be issued from January 25, 2002 through February 7, 2002.
The last biweekly notice was published on February 5, 2002 (67 FR
5323).
Notice of Consideration of Issuance of Amendments to Facility
Operating Licenses, Proposed No Significant Hazards Consideration
Determination, and Opportunity for a Hearing
The Commission has made a proposed determination that the following
amendment requests involve no significant hazards consideration. Under
the Commission's regulations in 10 CFR 50.92, this means that operation
of the facility in accordance with the proposed amendment would not (1)
involve a significant increase in the probability or consequences of an
accident previously evaluated; or (2) create the possibility of a new
or different kind of accident from any accident previously evaluated;
or (3) involve a significant reduction in a margin of safety. The basis
for this proposed determination for each amendment request is shown
below.
The Commission is seeking public comments on this proposed
determination. Any comments received within 30 days after the date of
publication of this notice will be considered in making any final
determination.
Normally, the Commission will not issue the amendment until the
expiration of the 30-day notice period. However, should circumstances
change during the notice period such that failure to act in a timely
way would result, for example, in derating or shutdown of the facility,
the Commission may issue the license amendment before the expiration of
the 30-day notice period, provided that its final determination is that
the amendment involves no significant hazards consideration. The final
determination will consider all public and State comments received
before action is taken. Should the Commission take this action, it will
publish in the Federal Register a notice of issuance and provide for
opportunity for a hearing after issuance. The Commission expects that
the need to take this action will occur very infrequently.
Written comments may be submitted by mail to the Chief, Rules and
Directives Branch, Division of Administrative Services, Office of
Administration, U.S. Nuclear Regulatory Commission, Washington, DC
20555-0001, and should cite the publication date and page number of
this Federal Register notice. Written comments may also be delivered to
Room 6D22, Two White Flint North, 11545 Rockville Pike, Rockville,
Maryland, from 7:30 a.m. to 4:15 p.m. Federal workdays. Copies of
written comments received may be examined at the NRC's Public Document
Room (PDR), located at One White Flint North, 11555 Rockville Pike
(first floor), Rockville, Maryland. The filing of requests for a
hearing and petitions for leave to intervene is discussed below.
By March 21, 2002, the licensee may file a request for a hearing
with respect to issuance of the amendment to the subject facility
operating license and any person whose interest may be affected by this
proceeding and who wishes to participate as a party in the proceeding
must file a written request for a hearing and a petition for leave to
intervene. Requests for a hearing and a petition for leave to intervene
shall be filed in accordance with the Commission's ``Rules of Practice
for Domestic Licensing Proceedings'' in 10 CFR part 2. Interested
persons should consult a current copy of 10 CFR 2.714, which is
available at the NRC's PDR, located at One White Flint North, 11555
Rockville Pike (first floor), Rockville, Maryland. Publicly available
records will be accessible from the Agencywide Documents Access and
Management Systems (ADAMS) Public Electronic Reading Room on the
internet at the NRC Web site, http://www.nrc.gov/reading-rm/doc-collections/cfr/. If a request for a hearing or petition for leave to
intervene is filed by the above date, the Commission or an Atomic
Safety and Licensing Board, designated by the Commission or by the
Chairman of the Atomic Safety and Licensing Board Panel, will rule on
the request and/or petition; and the Secretary or the designated Atomic
Safety and Licensing Board will issue a notice of a hearing or an
appropriate order.
As required by 10 CFR 2.714, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following factors: (1) The nature of the petitioner's right under the
Act to be made a party to the proceeding; (2) the nature and extent of
the petitioner's property, financial, or other interest in the
proceeding; and (3) the possible effect of any order which may be
entered in the proceeding on the petitioner's interest. The petition
should also identify the specific aspect(s) of the subject matter of
the proceeding as to which petitioner wishes to intervene. Any person
who has filed a petition for leave to intervene or who has been
admitted as a party may amend the petition without requesting leave of
the Board up to 15 days prior to the first
[[Page 7411]]
prehearing conference scheduled in the proceeding, but such an amended
petition must satisfy the specificity requirements described above.
Not later than 15 days prior to the first prehearing conference
scheduled in the proceeding, a petitioner shall file a supplement to
the petition to intervene which must include a list of the contentions
which are sought to be litigated in the matter. Each contention must
consist of a specific statement of the issue of law or fact to be
raised or controverted. In addition, the petitioner shall provide a
brief explanation of the bases of the contention and a concise
statement of the alleged facts or expert opinion which support the
contention and on which the petitioner intends to rely in proving the
contention at the hearing. The petitioner must also provide references
to those specific sources and documents of which the petitioner is
aware and on which the petitioner intends to rely to establish those
facts or expert opinion. Petitioner must provide sufficient information
to show that a genuine dispute exists with the applicant on a material
issue of law or fact. Contentions shall be limited to matters within
the scope of the amendment under consideration. The contention must be
one which, if proven, would entitle the petitioner to relief. A
petitioner who fails to file such a supplement which satisfies these
requirements with respect to at least one contention will not be
permitted to participate as a party.
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing, including the opportunity to present evidence and cross-
examine witnesses.
If a hearing is requested, the Commission will make a final
determination on the issue of no significant hazards consideration. The
final determination will serve to decide when the hearing is held.
If the final determination is that the amendment request involves
no significant hazards consideration, the Commission may issue the
amendment and make it immediately effective, notwithstanding the
request for a hearing. Any hearing held would take place after issuance
of the amendment.
If the final determination is that the amendment request involves a
significant hazards consideration, any hearing held would take place
before the issuance of any amendment.
A request for a hearing or a petition for leave to intervene must
be filed with the Secretary of the Commission, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001, Attention: Rulemaking and
Adjudications Staff, or may be delivered to the Commission's PDR,
located at One White Flint North, 11555 Rockville Pike (first floor),
Rockville, Maryland, by the above date. A copy of the petition should
also be sent to the Office of the General Counsel, U.S. Nuclear
Regulatory Commission, Washington, DC 20555-0001, and to the attorney
for the licensee.
Nontimely filings of petitions for leave to intervene, amended
petitions, supplemental petitions and/or requests for a hearing will
not be entertained absent a determination by the Commission, the
presiding officer or the Atomic Safety and Licensing Board that the
petition and/or request should be granted based upon a balancing of
factors specified in 10 CFR 2.714(a)(1)(i)-(v) and 2.714(d).

AmerGen Energy Company, LLC, Docket No. 50-461, Clinton Power Station,
Unit 1, DeWitt County, Illinois
Date of amendment request: November 30, 2001.
Description of amendment request: A change is proposed to
Surveillance Requirement (SR) 3.0.3 to allow a longer period of time to
perform a missed surveillance. The time is extended from the current
limit of ``* * * up to 24 hours or up to the limit of the specified
Frequency, whichever is less'' to ``* * * up to 24 hours or up to the
limit of the specified Frequency, whichever is greater.'' In addition,
the following requirement would be added to SR 3.0.3: ``A risk
evaluation shall be performed for any Surveillance delayed greater than
24 hours and the risk impact shall be managed.''
The Nuclear Regulatory Commission (NRC) staff issued a notice of
opportunity for comment in the Federal Register on June 14, 2001, (66
FR 32400), on possible amendments concerning missed surveillances,
including a model safety evaluation and model no significant hazards
consideration (NSHC) determination, using the consolidated line item
improvement process. The NRC staff subsequently issued a notice of
availability of the models for referencing in license amendment
applications in the Federal Register on September 28, 2001, (66 FR
49714). The licensees affirmed the applicability of the following NSHC
determination in its application dated November 30, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident Previously
Evaluated
The proposed change relaxes the time allowed to perform a missed
surveillance. The time between surveillances is not an initiator of
any accident previously evaluated. Consequently, the probability of
an accident previously evaluated is not significantly increased. The
equipment being tested is still required to be operable and capable
of performing the accident mitigation functions assumed in the
accident analysis. As a result, the consequences of any accident
previously evaluated are not significantly affected. Any reduction
in confidence that a standby system might fail to perform its safety
function due to a missed surveillance is small and would not, in the
absence of other unrelated failures, lead to an increase in
consequences beyond those estimated by existing analyses. The
addition of a requirement to assess and manage the risk introduced
by the missed surveillance will further minimize possible concerns.
Therefore, this change does not involve a significant increase in
the probability or consequences of an accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of a
New or Different Kind of Accident From Any Previously Evaluated
The proposed change does not involve a physical alteration of
the plant (no new or different type of equipment will be installed)
or a change in the methods governing normal plant operation. A
missed surveillance will not, in and of itself, introduce new
failure modes or effects and any increased chance that a standby
system might fail to perform its safety function due to a missed
surveillance would not, in the absence of other unrelated failures,
lead to an accident beyond those previously evaluated. The addition
of a requirement to assess and manage the risk introduced by the
missed surveillance will further minimize possible concerns. Thus,
this change does not create the possibility of a new or different
kind of
[[Page 7412]]
accident from any accident previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety
The extended time allowed to perform a missed surveillance does
not result in a significant reduction in the margin of safety. As
supported by the historical data, the likely outcome of any
surveillance is verification that the LCO [Limiting Condition for
Operation] is met. Failure to perform a surveillance within the
prescribed frequency does not cause equipment to become inoperable.
The only effect of the additional time allowed to perform a missed
surveillance on the margin of safety is the extension of the time
until inoperable equipment is discovered to be inoperable by the
missed surveillance. However, given the rare occurrence of
inoperable equipment, and the rare occurrence of a missed
surveillance, a missed surveillance on inoperable equipment would be
very unlikely. This must be balanced against the real risk of
manipulating the plant equipment or condition to perform the missed
surveillance. In addition, parallel trains and alternate equipment
are typically available to perform the safety function of the
equipment not tested. Thus, there is confidence that the equipment
can perform its assumed safety function. Therefore, this change does
not involve a significant reduction in a margin of safety.
Based upon the reasoning presented above and the previous
discussion of the amendment request, the requested change does not
involve a significant hazards consideration.
The NRC staff has reviewed the licensees' analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
requested amendments involve no significant hazards consideration.

Arizona Public Service Company, et al., Docket No. STN 50-529, Palo
Verde Nuclear Generating Station, Unit 2, Maricopa County, Arizona
Date of amendment request: December 21, 2001.
Description of amendment request: The amendment would revise the
operating license and the Technical Specifications (TSs) to support
replacement of the steam generators and the subsequent increased power
to a level of 3990 MWt, a 2.94 percent increase.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
a. Evaluation of the Probability of Previously Evaluated Accidents
Plant Structures, Systems and Components (SSCs) have been
verified to be capable of performing their intended design functions
at uprated power conditions. Where necessary, a small number of
minor modifications will be made prior to implementation of uprated
power operations so that surveillance test acceptance criteria
continues to be met. The analysis has concluded that operation at
uprated power conditions will not adversely affect the capability or
reliability of plant equipment. Current technical specification
surveillance requirements ensure frequent and adequate monitoring of
system and component operability. All systems will continue to be
operated within current operating requirements at uprated
conditions. Therefore, no new structure, system or component
interactions have been identified that could lead to an increase in
the probability of any accident previously evaluated in the Updated
Final Safety Analysis Report (UFSAR).
b. Evaluation of the Consequences of Previously Evaluated Accidents
The radiological consequences were reviewed for all design basis
accidents (DBAs) (i.e., both LOCA [loss-of-coolant accident] and
non-LOCA accidents) previously analyzed in the UFSAR. The analyses
showed that the resultant radiological consequences for both LOCA
and non-LOCA accidents remained within regulatory and Standard
Review Plan (SRP) limits at uprated power conditions.
2. The proposed change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
The configuration, operation and accident response of the PVNGS
[Palo Verde Nuclear Generating Station] Unit 2 SSCs are unchanged by
operation at uprated power conditions or by the associated proposed
TS changes. Analyses of transient events have confirmed that no
transient event results in a new sequence of events that could lead
to a new accident or different scenario.
The effect of operation at uprated power conditions on plant
equipment has been evaluated. No new operating mode, safety-related
equipment lineup, accident scenario, or equipment failure mode was
identified as a result of operating at uprated conditions. In
addition, operation at uprated power conditions does not create any
new failure modes that could lead to a different kind of accident.
Minor plant modifications, to support implementation of uprated
power conditions, will be made as required to existing SSCs. The
basic design function of all SSCs remains unchanged and no new
equipment or systems have been installed that could potentially
introduce new failure modes or accident sequences.
Based on these analyses, it is concluded that no new accident
scenarios, failure mechanisms or limiting single failures are
introduced as a result of the proposed changes. The proposed changes
do not have an adverse effect on any safety-related system or design
basis function. Therefore, the proposed changes do not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. The proposed change does not involve a significant reduction
in a margin of safety.
A comprehensive analysis was performed to evaluate the effects
of power uprate on PVNGS Unit 2. This analysis identified and
defined the major input parameters to the NSSS [nuclear steam supply
system], reviewed NSSS design transients, and reviewed the
capabilities of the NSSS and BOP [balance-of-plant] fluid systems,
NSSS/BOP interfaces, NSSS and BOP control systems, and NSSS and BOP
SSCs. NSSS accident analyses were re-performed or reviewed to
confirm that acceptable results were maintained and that the
radiological consequences remained within regulatory and SRP limits.
The nuclear and thermal hydraulic performance of nuclear fuel was
also reviewed to confirm acceptable results. The analyses confirmed
that all NSSS and BOP SSCs are capable, some with minor
modifications, to safely support operations at uprated power
conditions.
The margin of safety of the reactor coolant pressure boundary is
maintained under uprated power conditions. The design pressure of
the reactor pressure vessel and reactor coolant system will not be
challenged as the pressure mitigating systems were confirmed to be
sufficiently sized to adequately control pressure under uprated
power conditions.
Reanalysis of containment structural integrity under DBA
conditions indicates that the calculated peak containment pressure
(Pa) increases from 52.0 psig to 58.0 psig, but remains less than
the containment internal design pressure of 60 psig. The proposed
value for Pa has been rounded up from the actual calculated value of
57.85 psig.
Radiological consequences of the following accidents were
reviewed: Main Steam Line Break, Locked Reactor Coolant Pump (RCP)
Rotor, CEA Ejection, Small Steam Line Break Outside Containment,
Steam Generator Tube Rupture, LBLOCA [large break loss of coolant
accident], SBLOCA [small break loss of coolant accident], Waste Gas
Decay Tank Rupture, Liquid Waste Tank Failure, and Fuel Handling
Accident. The resultant radiological consequences for each of these
accidents remained within regulatory and SRP limits at uprated power
conditions.
The analyses supporting operation at power uprate conditions
have demonstrated that all systems and components are capable of
safely operating at uprated power conditions. All DBA acceptance
criteria will continue to be met. Therefore, it is concluded that
the proposed changes do not involve a significant reduction in the
margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
that review, it appears that the three
[[Page 7413]]
standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff
proposes to determine that the request for an amendment involves no
significant hazards consideration.

Calvert Cliffs Nuclear Power Plant, Inc., Docket No. 50-317, Calvert
Cliffs Nuclear Power Plant, Unit No. 1, Calvert County, Maryland
Date of amendment request: January 31, 2002.
Description of amendment request: The proposed amendment would
allow a one-time five-year extension, for a total of 15 years, for the
performance of the next Unit 1 integrated leak rate test (ILRT). The
proposed amendment would also exempt Unit 1 from the requirement to
perform a post-modification containment ILRT associated with the steam
generator replacement.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration which is presented below:
1. Would not involve a significant increase in the probability
or consequences of an accident previously evaluated:
[Extension of Type A integrated leakage rate testing:]
This proposed one-time extension of the Type A test interval
does not increase the probability of an accident since there are no
design or operating changes involved and the test is not an accident
initiator. The proposed extension of the test interval does not
involve a significant increase in the consequences of an accident
since research documented in NUREG-1493 has found that, generically,
fewer than three percent of the potential containment leak paths are
not identified by Type B and C testing. Calvert Cliffs, through
testing and containment inspections, also provides a high degree of
assurance that the Containment will not degrade in a manner
detectable only by a Type A test. Inspections required by the
Maintenance Rule (10 CFR 50.65) and by the American Society of
Mechanical Engineers Boiler and Pressure Vessel Code are performed
to identify containment degradation that could affect leak
tightness.
Therefore, this change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
[Exemption from post-modification testing:]
The steam generator replacement activities do not affect the
containment structure or the actual containment liner. Access for
the replacement steam generators as well as removal of the old steam
generators will be through the equipment hatch. However, the outer
shell of the steam generators, the inside containment portions of
the main steam line, the feedwater lines, the auxiliary feedwater
lines, and the steam generator blowdown lines are all part of the
primary reactor containment boundary that will be impacted by the
replacement activities.
Calvert Cliffs Nuclear Power Plant Technical Specification
5.5.16 states, ``A program shall be established to implement the
leakage testing of the Containment as required by 10 CFR 50.54(o)
and 10 CFR part 50, Appendix J, Option B. This program shall be in
accordance with the guidelines contained in Regulatory Guide 1.163,
`Performance-Based Containment Leak-Test Program' dated September
1995, including errata.'' Regulatory Guide 1.163, ``Performance-
Based Containment Leak-Test Program,'' endorses NEI [Nuclear Energy
Institute] 94-01, Revision 0 for methods acceptable to comply with
the requirements of Option B. Prior to returning the Containment to
operation, NEI 94-01 requires leakage rate testing (Type A testing
or local leakage rate testing), following repairs and modification
that affect the containment leakage integrity.
The affected area of the primary containment boundary is also
part of the pressure boundary of an American Society of Mechanical
Engineers (ASME) Class 2 component/piping system and, as such, the
planned replacement of the steam generators are subject to the
repair and replacement requirements of ASME Section XI. The ASME
Section XI surface examination, volumetric examination, and system
pressure test requirements are more stringent than the Appendix J,
Option B testing requirements. The acceptance criteria for ASME
Section XI system pressure testing of welded joints is ``zero
leakage.'' In addition, the test pressure for the system pressure
test will be approximately 17 times that of Appendix J, Option B
test.
The objective of the Type A test is to assure the leak-tight
integrity of the area affected by the modification. Although the
leak test is in a direction reverse to that of the design basis
accident environment, the ASME Section XI inspection and testing
requirements more than fulfill the intent of the requirements of
Appendix J, Option B with the exception of secondary side access
manways. Section 9.2.1, NEI 94-01, Revision 0 allows reverse testing
if justified. Section XI pressure test applies a sealing pressure to
the secondary manway due to the inward door swing configuration.
Hence, a Type B local leak rate test will be performed for the
secondary manways. For all other affected components, reverse
testing is justified since the acceptance criteria for ASME Section
XI system pressure testing of welded joints is ``zero leakage,'' and
the test pressure of the system pressure test will be approximately
17 times that of a Type A test. Hence, the probability or
consequences of design bases accidents previously evaluated are
unchanged.
Therefore, the proposed revision to Technical Specification
5.5.16 to eliminate the requirement to perform post-modification
containment integrated leakage rate testing following replacement of
Unit 1 steam generators will not involve a significant increase in
the probability or consequences of an accident previously evaluated.
2. Would not create the possibility of a new or different type
of accident from any accident previously evaluated.
[Extension of Type A integrated leakage rate test interval:]
This proposed one-time extension to the interval for the Type A
test does not involve any design or operational changes that could
lead to a new or different kind of accident from any accident
previously evaluated. The test itself is not changing and will be
performed after a longer interval. The proposed change does not
involve a physical alteration of the plant (no new or different type
of equipment will be installed) or a change in the methods governing
normal plant operation.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
[Exemption from post-modification testing:]
The proposed revision does not involve a physical change to the
plant and there are no changes to the operation of the plant that
could introduce a new failure mode. As described above in Item 1,
the objective of the Appendix J, Option B test is to assure that
leak-tight integrity of the area affected by the modification. The
ASME Section XI inspection and testing requirements are more
stringent than the Appendix J, Option B testing requirements.
Therefore, the proposed revision to Technical Specification
5.5.16 to eliminate the requirement to perform post-modification
containment integrated leakage rate testing following replacement of
Unit 1 steam generators will not create the possibility of a new or
different [kind] of accident from any previously evaluated.
3. Would not involve a significant reduction in the margin of
safety.
[Extension of Type A integrated leakage rate test interval:]
The generic study of the increase in the Type A test interval,
NUREG-1493, concluded there is an imperceptible increase in the
plant risk associated with extending the test interval out to 20
years. Further, the extended test interval would have a minimal
effect on this risk since Type B and C testing detect 97 percent of
potential leakage paths. For the requested change in the Calvert
Cliffs Integrated Leakage Rate Test interval, it was determined that
the risk contribution of leakage will increase 0.07 percent (based
on change in offsite dose). This change is considered very small and
does not represent a significant reduction in the margin of safety.
Therefore, this change does not involve a significant reduction
in the margin of safety.
[Exemption from post-modification testing:]
As described above in Item 1, the ASME Section XI surface
examination, volumetric examination, and system pressure test
requirements are more stringent than the Appendix J, Option B
testing requirements. The acceptance criteria for ASME Section XI
[[Page 7414]]
system pressure testing of welded joints is ``zero leakage.'' In
addition, the test pressure for the system pressure test will be
approximately 17 times that of Appendix J, Option B test.
Therefore, the proposed revision to Technical Specification
5.5.16 to eliminate the requirement to perform post-modification
containment integrated leakage rate testing following replacement of
Unit 1 steam generators does not involve a significant reduction in
the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposed to determine that the
amendment request involves no significant hazards consideration.

Dominion Nuclear Connecticut, Inc., Docket No. 50-336, Millstone
Nuclear Power Station, Unit No. 2, New London County, Connecticut
Date of amendment request: November 6, 2001, as supplemented
December 27, 2001.
Description of amendment request: The proposed amendment would: 1)
Increase the allowable nominal average fuel assembly enrichment from
4.5 w/o U-235 to 4.85 w/o U-235 for all regions of the spent fuel pool,
the new fuel storage racks (dry), and the reactor core; 2) Allow fuel
to be located under the cell blockers in 40 empty Region B storage
cells; and, 3) Credit spent fuel pool soluble boron for reactivity
control during normal conditions to maintain spent fuel pool
Keff 0.95.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
Previously evaluated Final Safety Analysis Report (FSAR) Chapter
14 accidents are a fuel handling accident either in the spent fuel
pool (SFP) or in containment, and a spent fuel cask drop accident.
Since there are no changes to plant equipment, nor any changes in
how fuel is moved, there are no changes to the probability of a fuel
handling accident in the spent fuel pool or containment.
Since there are no changes to plant equipment, nor any changes
in how a shielded cask would be moved, there are no changes to the
probability of a spent fuel cask drop accident.
The consequences of a fuel drop accident in either containment
or the spent fuel pool are not affected, since none of the inputs to
these fuel drop accidents is affected. There are no physical
hardware changes made to the plant. The limiting fuel burnup is not
changed, nor is there any change in the source term of radioactivity
present in the fuel. Allowing fuel to be stored in the 40 Region B
locations currently empty, does not alter the existing FSAR
conclusion that a dropped fuel assembly or consolidated storage box
could not strike more than one fuel assembly in the storage rack.
This is still true since the fuel stored in these 40 locations is
stored at the same elevation as fuel in any other storage locations.
The FSAR states that the worst fuel handling incident that could
occur in the SFP is the drop of a fuel assembly to the pool floor,
with resultant failure of 14 fuel rods when the assembly rotates and
impacts a protruding structure. Radiological consequences for both
the failure of 14 rods and the entire fuel assembly are presented in
the FSAR. The storage of fuel in the 40 currently blocked locations
does not affect this FSAR sequence of events for the dropped fuel
assembly in the SFP accident. The amount of soluble boron
concentration necessary in the SFP to ensure that Keff is
maintained 0.95 on a 95/95 bases is increased from 800
ppm to 1400 ppm. However, this increase in required SFP soluble
boron concentration does not increase any dose consequences from the
fuel drop accident in the SFP. The increase in soluble boron
concentration from 800 ppm to 1400 ppm is a result of crediting an
additional 600 ppm of SFP soluble boron under normal conditions.
The consequences of a spent fuel cask drop accident in the SFP
is not affected, since none of the inputs to the spent fuel cask
drop accident is affected. There are no physical hardware changes
made to the plant. The limiting fuel burnup is not changed, nor is
there any change in the source term of radioactivity present in the
fuel. The amount of soluble boron concentration necessary in the SFP
to ensure that Keff is maintained 0.95 on a
95/95 bases is increased from 800 ppm to 1400 ppm. However, this
increase in required SFP soluble boron concentration does not
increase any dose consequences from the spent fuel cask drop
accident in the SFP. The increase in soluble boron concentration
from 800 ppm to 1400 ppm is a result of crediting an additional 600
ppm of SFP soluble boron under normal conditions.
With regard to the proposed change in the design features
section of Technical Specifications (TS), which would allow higher
enrichments in the new fuel storage (dry) vault, there are no FSAR
Chapter 14 accident conditions currently analyzed, therefore there
can be no change in probability or consequences of an existing
accident.
With regard to the proposed change in the design features
section of TS, which would allow higher enrichments in the reactor
core, enrichment by itself is not a parameter which will affect the
probability or consequences of an accident previously analyzed. The
effects of enrichment on other reactor core parameters such as
shutdown margin, MTC [moderator temperature coefficient] and power
distributions is considered by meeting the exi[s]ting TS
requirements for these parameters. Also, the reactor core
radioactive source term is not affected since the exiting design
basis analysis bounds use of the proposed enrichment. Therefore, a
change in the maximum enrichment limit will not impact any safety
analyses because the important inputs to these analyses are
protected by Technical Specifications. Since there are no changes to
these existing reactor core TS parameter limits, there will be no
effect on the probability or consequences of an accident previously
analyzed.
Therefore, based on the above analysis, the proposed changes do
not involve a significant increase in the probability or
consequences of an accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
The changes to be made primarily affect nuclear criticality
analysis and do not create a new or different kind of accident.
Changes in allowed enrichment, boraflex credit, soluble boron
credit, and allowing fuel to be stored in 40 additional locations
are all impacts to the SFP criticality analysis. The SFP criticality
analysis is part of the basic design of the system and is not an
accident. The ability to maintain the SFP Keff
0.95, as well as within the 10 CFR 50 App. A GDC62
criteria [General Design Criterion (GDC)-62, ``Prevention of
criticality in fuel storage and handling,'' of Appendix A, ``General
Design Criteria for Nuclear Power Plants,'' to 10 CFR part 50] of
sub-critical have been evaluated. Criticality impacts are more
appropriately discussed under the margin of safety criterion.
Since there are no changes to the plant equipment, there is no
possibility of a new or different kind of accident being initiated
or affected by equipment issues. There are no changes in how fuel is
moved or qualified for storage, so a new accident cannot be
initiated from fuel handling related procedures.
Higher SFP soluble boron concentrations are required than
previously required to compensate for the positive reactivity
insertions from postulated accident conditions (i.e., dropped cask).
However, merely increasing the amount of SFP soluble boron required
for compensating for the existing analyzed accident does not create
the potential for a new or different kind of accident.
With regard to the proposed change in the design section of TS,
which would allow higher enrichments in the new fuel storage (dry)
vault, no new or different kind of accident conditions are created.
The existing new fuel storage analysis previously submitted to the
NRC is not altered, and already bounds enrichments up to 5.0 w/o U-
235.
With regard to the proposed change in the design features
section of TS, which would allow higher enrichments in the reactor
core, the higher enrichment fuel in the reactor core does not
require any new or different plant
[[Page 7415]]
equipment, and does not change the manner in which currently
installed equipment is operated. There are no changes to normal core
operation, and the unit will meet all applicable design criteria and
will operate within the existing reactor core TS limits. No new
failure modes have been created for any system, component or piece
of equipment, and no new single failure mechanisms are introduced.
Therefore, allowing higher enrichments in the reactor core will not
create a new or different kind of accident condition.
Therefore, based on the above analysis, the proposed changes do
not create the possibility of a new or different kind of accident
from any accident previously evaluated.
3. Involve a significant reduction in a margin of safety.
The margin of safety relevant to the SFP are:
To ensure that the SFP Keff remains
0.95 on a 95/95 basis to ensure the criticality safety
of the SFP.
To ensure that the spent fuel in the SFP remains
adequately cooled so that the fission product barriers remain
intact.
A criticality analysis has been performed to ensure that the
spent fuel pool Keff remains 0.95 on a 95/95
basis under all normal and postulated accident conditions. Thus the
margin of criticality safety is not changed. Most of the changes in
the criticality analysis are of an input nature, such as a change in
allowed enrichment. The only change in methodology is the crediting
of soluble boron for normal conditions. The approach used is
consistent with WCAP-14416-NP-A. The NRC has previously approved for
other plants similar applications for soluble boron credit for
normal conditions. The criticality analysis has been performed to
ensure that the spent fuel pool Keff remains less than
1.00 on a 95/95 basis even with 0 ppm soluble boron concentration in
the SFP. This ensures compliance with GDC62.
The only change that could affect the SFP cooling analysis is
allowing 40 additional fuel assemblies to be stored in the SFP. The
current design basis heat load analysis already bounds the storage
of these fuel assemblies. This ensures that the spent fuel in the
SFP remains adequately cooled so that the fission product barriers
remain intact. The current design basis heat load analysis bounds
the increased fuel storage.
With regard to the proposed change in the design section of TS,
which would allow higher enrichments in the new fuel storage (dry)
vault, there is no significant reduction in the margin of safety.
The existing new fuel storage analysis previously submitted and
approved by the NRC is not altered, and already bounds enrichments
up to 5.0 w/o U-235, to ensure that Keff of the new fuel
storage racks is maintained 0.95.
With regard to the proposed change in the design features
section of TS, which would allow higher enrichments in the reactor
core, enrichment by itself is not a parameter which will affect the
margin of safety. The margins of safety, such as fuel DNB
protection, fuel melt protection and RCS boundary protection, are
met by complying with the safety analysis and associated TS limits.
The effects of enrichment on other reactor core parameters such as
shutdown margin, MTC and power distributions is considered by
meeting the existing TS requirements for these parameters.
Therefore, a change in the maximum core enrichment limit will not
impact any margins of safety because the important inputs to the
safety analyses are protected by Technical Specifications. Since
there are no change[s] to these existing reactor core TS parameter
limits, there will be no effect on the margin of safety.
Therefore, based on the above analysis, the proposed changes do
not involve a reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Duke Energy Corporation, et al., Docket Nos. 50-413 and 50-414, Catawba
Nuclear Station, Units 1 and 2, York County, South Carolina
Date of amendment request: December 20, 2001.
Description of amendment request: The amendments would revise the
Technical Specifications (TS) for Catawba Nuclear Station, Units 1 and
2, based on a revised radiological dose consequence analysis of a
postulated fuel handling accident and weir gate drop accident. The
licensee has requested these amendments in accordance with the
requirements of 10 CFR 50.67 which addresses the use of an alternate
source term at operating reactors, and relevant guidance provided in
Regulatory Guide (RG) 1.183.
Specifically, the proposed changes would revise TS 3.7.10, Control
Room Area Ventilation System (CRAVS), to require immediate suspension
of movement of irradiated fuel with less than two trains of the CRAVS
operable. This change is being requested to correct a non-conservatism
in this TS.
The proposed change to TS 3.7.11, Control Room Area Chilled Water
System, would delete the applicability of the specification during core
alterations and during movement of irradiated fuel. This system is not
credited as a mitigation system for the postulated fuel handling
accident or weir gate drop accident.
The proposed change to TS 3.7.13, Fuel Handling Ventilation Exhaust
System, would change the Limiting Condition for Operation to require
two trains be operable during the movement of recently irradiated fuel
in the fuel building, and to require that movement of recently
irradiated fuel in the fuel building be suspended if one train becomes
inoperable. Recently irradiated fuel is defined as fuel that has
occupied part of a critical reactor core within the previous 72 hours.
Operability of the Fuel Handling Ventilation Exhaust System would only
be required during movement of recently irradiated fuel assemblies.
This change is being requested to incorporate the concept of recently
irradiated fuel and to correct a non-conservatism in this TS.
The proposed change to TS 3.9.3, Containment Penetrations, would
amend the applicability of this specification. Current TS requirements
regarding closure of the containment equipment hatch, the personnel
airlock and containment penetrations would only apply during movement
of recently irradiated fuel assemblies. The applicability of this
specification during core alterations would be deleted.
The licensee is requesting these amendments to provide flexibility
in scheduling outage tasks and to modify unnecessarily restrictive
containment closure and fuel handling building ventilation system
requirements. The revised analyses also incorporate updated atmospheric
dispersion factors for the Control Room intake pathway.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
Does operation of the facility in accordance with the proposed
amendment involve a significant increase in the probability or
consequences of an accident previously evaluated? No.
An alternate source term calculation has been performed for
Catawba Nuclear Station that demonstrates that offsite dose
consequences of a postulated fuel handling accident or weir gate
drop accident remain within the limits provided sufficient decay has
occurred prior to the movement of irradiated fuel without taking
credit for certain mitigation features such as ventilation filter
systems and containment closure. Irradiated fuel that has not
undergone the required decay period of 72 hours is defined to be
recently irradiated fuel and the currently approved Technical
Specification requirements are applicable when this recently
irradiated fuel is being handled.
The proposed amendment would allow core alterations and movement
of sufficiently decayed irradiated fuel within the containment
building with the equipment hatch, personnel air locks and
containment penetrations open. Operation of the
[[Page 7416]]
Containment Purge Exhaust System (CPES) is not required during
movement of sufficiently decayed fuel. The amendment also would
allow movement of irradiated fuel assemblies within the fuel
building without the Fuel Handling Ventilation Exhaust System
(FHVES) in operation. Movement of the weir gate is permitted without
the FHVES in operation provided the irradiated fuel that could be
impacted by a drop of the weir gate has undergone a minimum decay
period of 19.5 days.
This amendment does not alter the methodology or equipment used
directly in fuel handling operations and weir gate movement. Neither
ventilation filter systems, the CPES nor the FHVES, is used to
actually handle fuel. Neither of these systems is an ``accident
initiator'' either in this sense or any other sense. Similarly,
neither the equipment hatch, the personnel air locks, nor any other
containment penetration, nor any component thereof is an accident
initiator.
Actual fuel handling operations and weir gate movement
themselves are not affected by the proposed changes. Therefore, the
probability of a Fuel Handling Accident and Weir Gate Drop is not
affected with the proposed amendment. No other accident initiator is
affected by the proposed changes.
For the reasons above, the proposed amendment does not involve a
significant increase in the probability of an accident previously
evaluated.
The Fuel Handling Accident in Containment has been analyzed
without credit for filtration by the CPES. Likewise, the Fuel
Handling Accident in the Fuel Building and the Weir Gate Drop has
been analyzed without credit for filtration by the FHVES. The
analyses of these design basis events were conducted with the
Alternative Source Term Methodology in accordance with 10 CFR 50.67
and Regulatory Guide 1.183. These analyses show that the resultant
radiation doses are within the limits specified in 10 CFR 50.67 and
R.G. 1.183.
The TEDE [total effective dose equivalent] radiation doses from
the analyses supporting this LAR [license amendment request] have
been compared to equivalent TEDE radiation doses estimated with the
guidelines of R.G. 1.183 Footnote 7. The new values are shown to be
comparable to the results of the previous analyses.
For the reasons above, the proposed amendment does not involve a
significant increase in the consequences of an accident previously
evaluated.
Does operation of the proposed facility in accordance with the
proposed amendment create the possibility of a new or different kind
of accident from any accident previously evaluated? No.
The proposed change does not involve addition or modification to
any plant system, structure, or component. The proposed amendment
would increase the time during which the equipment hatch and
personnel air locks could be open during core alterations and
movement of irradiated fuel. The proposed amendment does not involve
any change in the operation of these containment penetrations.
Having these penetrations open does not create the possibility of a
new accident.
The proposed amendment also would remove the requirements for
operability of the CPES and FHVES during core alterations or
movement of sufficiently decayed irradiated fuel. It does not alter
the operation of these systems beyond their functional capabilities.
Modification of the requirements of operability for these systems
from the plant Technical Specifications does not create the
possibility of a new accident.
The requirements for CRAVS are being revised to immediately
suspend movement of irradiated fuel if one CRAVS train becomes
inoperable. This change does not have the potential to cause a new
or different type of accident.
The proposed amendment does not create the possibility of a new
or different kind of accident than any previously evaluated.
Does operation of the facility in accordance with the proposed
amendment involve a significant reduction in the margin of safety?
No.
The assumptions and input used in the analysis are conservative
as noted below. The design basis Fuel Handling Accidents and Weir
Gate Drop have been defined to identify conservative conditions
(concerning offsite power and single failure). The source term and
radioactivity releases have been calculated pursuant to Regulatory
Guide 1.183 and with conservative assumptions concerning prior
reactor operation. The control room atmospheric dispersion factors
have been calculated with conservative assumptions associated with
the release. The conservative assumptions and input noted above
ensure that the radiation doses cited in this License Amendment
Request are the upper bound to radiological consequences of a Fuel
Handling Accident either in Containment or the Fuel Building and the
Weir Gate Drop. The analyses show that there is a significant margin
between the TEDE radiation doses calculated for the postulated Fuel
Handling Accident and the Weir Gate Drop accident using the
Alternative Source Term and the acceptance limits of 10 CFR 50.67
and Regulatory Guide 1.183.
The proposed change does not involve a significant reduction in
the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Operations, Inc., Docket No. 50-313, Arkansas Nuclear One, Unit
No. 1, Pope County, Arkansas
Date of amendment request: January 31, 2002.
Description of amendment request: The proposed amendment revises
Technical Specification 5.6.5, ``Core Operating Limits Report (COLR),''
to include an additional reference to Entergy Operations, Inc.
(Entergy) Topical Report ENEAD-01-P, ``Qualification of Reactor Physics
Methods for Pressurized Water Reactors of the Entergy System.'' This
topical report documents a Nuclear Regulatory Commission (NRC)-approved
methodology that can be utilized to determine core operating limits.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed change to add the Entergy Topical Report ENEAD-01-
P, ``Qualification of Reactor Physics Methods for Pressurized Water
Reactors of the Entergy System,'' to the Core Operating Limits
Report (COLR) references is administrative in nature. The topical
report has been reviewed and approved by the NRC in [a] Safety
Evaluation Report dated September 29, 1995 (0CNA099519). The
physical design or operation of the plant is not impacted by this
proposed change. The proposed change does not adversely impact
transient analysis assumptions or results. The COLR-related safety
analyses will continue to be performed utilizing NRC-approved
methodologies, and specific reload changes will be evaluated under
the provisions of 10 CFR 50.59.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
Adding a reference in the technical specifications to the NRC-
approved methodology in Entergy Topical Report ENEAD-01-P is
administrative in nature. No physical alterations of plant
configuration, changes to the plant operating procedures, or
operating parameters are proposed. No new equipment is being
introduced, and no equipment is being operated in a manner
inconsistent with its design. The COLR-related safety analyses will
continue to be performed utilizing NRC-approved methodologies. A 10
CFR 50.59 review will continue to be performed to evaluate specific
reload changes.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
[[Page 7417]]
The proposed change to reference Entergy Topical Report ENEAD-
01-P is administrative in nature. Existing technical specification
operability and surveillance requirements are not reduced by the
proposed change. The cycle-specific COLR limits for future reloads
will continue to be developed based on NRC-approved methodologies
and their corresponding physics parameter uncertainties. Technical
specifications will continue to require that the core be operated
within these limits and specify appropriate actions to be taken if
the limits are violated. The COLR-related safety analyses will
continue to be performed utilizing NRC-approved methodologies, and
specific reload changes will be evaluated per 10 CFR 50.59.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Operations, Inc., Docket No. 50-313, Arkansas Nuclear One, Unit
No. 1, Pope County, Arkansas
Date of amendment request: January 31, 2002.
Description of amendment request: The proposed amendment changes
administrative Technical Specification 5.5.16 regarding Containment
Integrated Leak Rate Testing (ILRT). The change clarifies the statement
that the ILRT Program is in accordance with Regulatory Guide 1.163,
``Performance-Based Containment Leak-Test Program,'' by noting an
exception based on Nuclear Energy Institute 94-01, ``Industry Guideline
for Implementing Performance-Based Option of 10 CFR 50, Appendix J.''
The effect of this change will be to allow a one-time extension of the
interval (to 15 years) for performance of the next ILRT.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
[Appendix J [of] 10 CFR [part] 50] was amended to incorporate
provisions for performance-based testing in 1995. The proposed
amendment to Technical Specification (TS) 5.5.16 adds a one-time
extension to the current interval for Type A testing (i.e., the
integrated leak rate test). The current interval of ten years, based
on past performance, would be extended on a one-time basis to 15-
years from the date of the last test. The proposed extension to the
Type A test cannot increase the probability of an accident since
there are no design or operating changes involved and the test is
not an accident initiator. The proposed extension of the test
interval does not involve a significant increase in the consequences
since research documented in NUREG-1493, ``Performance Based
Containment Leak Rate Test Program,'' has found that, generically,
fewer than 3% of the potential containment leak paths are not
identified by Type B and C testing. In addition, at ANO-1 [Arkansas
Nuclear One, Unit 1,] the testing and containment inspections also
provide a high degree of assurance that the containment will not
degrade in a manner detectable only by a Type A test. Inspections
required by the Maintenance Rule (10 CFR 50.65) and by the American
Society of Mechanical Engineers Boiler and Pressure Vessel Code are
performed to identify containment degradation that could affect
leaktightness.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The proposed extension to the interval for the Type A test does
not involve any design or operational changes that could lead to a
new or different kind of accident from any accidents previously
evaluated. The test itself is not being modified, but is only
intended to be performed after a longer interval. The proposed
change does not involve a physical alteration of the plant (no new
or different type of equipment will be installed) or a change in the
methods governing normal plant operation.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No. The generic study of the increase in the Type A
test interval, NUREG-1493, concluded there is an imperceptible
increase in the plant risk associated with extending the test
interval out to twenty years. Further, the extended test interval
would have a minimal effect on this risk since Type B and C testing
detect 97% of potential leakage paths. For the requested change in
the ANO-1 ILRT interval, it was determined that the risk
contribution of leakage will increase 0.19%. This change is
considered very small and does not represent a significant reduction
in the margin of safety.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Date of amendment request: November 30, 2001.
Description of amendment request: A change is proposed to
Surveillance Requirement (SR) 3.0.3 to allow a longer period of time to
perform a missed surveillance. The time is extended from the current
limit of ``* * * up to 24 hours or up to the limit of the specified
Frequency, whichever is less'' to ``. . . up to 24 hours or up to the
limit of the specified Frequency, whichever is greater.'' In addition,
the following requirement would be added to SR 3.0.3: ``A risk
evaluation shall be performed for any Surveillance delayed greater than
24 hours and the risk impact shall be managed.''
The Nuclear Regulatory Commission (NRC) staff issued a notice of
opportunity for comment in the Federal Register on June 14, 2001, (66
FR 32400), on possible amendments concerning missed surveillances,
including a model safety evaluation and model no significant hazards
consideration (NSHC) determination, using the consolidated line item
improvement process. The NRC staff subsequently issued a notice of
availability of the models for referencing in license amendment
applications in the Federal Register on September 28, 2001, (66 FR
49714). The licensees
[[Page 7418]]
affirmed the applicability of the following NSHC determination in its
application dated November 30, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), an analysis of the issue
of no significant hazards consideration is presented below:
Criterion 1--The Proposed Change Does Not Involve a Significant
Increase in the Probability or Consequences of an Accident Previously
Evaluated
The proposed change relaxes the time allowed to perform a missed
surveillance. The time between surveillances is not an initiator of
any accident previously evaluated. Consequently, the probability of
an accident previously evaluated is not significantly increased. The
equipment being tested is still required to be operable and capable
of performing the accident mitigation functions assumed in the
accident analysis. As a result, the consequences of any accident
previously evaluated are not significantly affected. Any reduction
in confidence that a standby system might fail to perform its safety
function due to a missed surveillance is small and would not, in the
absence of other unrelated failures, lead to an increase in
consequences beyond those estimated by existing analyses. The
addition of a requirement to assess and manage the risk introduced
by the missed surveillance will further minimize possible concerns.
Therefore, this change does not involve a significant increase in
the probability or consequences of an accident previously evaluated.
Criterion 2--The Proposed Change Does Not Create the Possibility of a
New or Different Kind of Accident From Any Previously Evaluated
The proposed change does not involve a physical alteration of
the plant (no new or different type of equipment will be installed)
or a change in the methods governing normal plant operation. A
missed surveillance will not, in and of itself, introduce new
failure modes or effects and any increased chance that a standby
system might fail to perform its safety function due to a missed
surveillance would not, in the absence of other unrelated failures,
lead to an accident beyond those previously evaluated. The addition
of a requirement to assess and manage the risk introduced by the
missed surveillance will further minimize possible concerns. Thus,
this change does not create the possibility of a new or different
kind of accident from any accident previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety
The extended time allowed to perform a missed surveillance does
not result in a significant reduction in the margin of safety. As
supported by the historical data, the likely outcome of any
surveillance is verification that the LCO [Limiting Condition for
Operation] is met. Failure to perform a surveillance within the
prescribed frequency does not cause equipment to become inoperable.
The only effect of the additional time allowed to perform a missed
surveillance on the margin of safety is the extension of the time
until inoperable equipment is discovered to be inoperable by the
missed surveillance. However, given the rare occurrence of
inoperable equipment, and the rare occurrence of a missed
surveillance, a missed surveillance on inoperable equipment would be
very unlikely. This must be balanced against the real risk of
manipulating the plant equipment or condition to perform the missed
surveillance. In addition, parallel trains and alternate equipment
are typically available to perform the safety function of the
equipment not tested. Thus, there is confidence that the equipment
can perform its assumed safety function. Therefore, this change does
not involve a significant reduction in a margin of safety.
Based upon the reasoning presented above and the previous
discussion of the amendment request, the requested change does not
involve a significant hazards consideration.
The NRC staff has reviewed the licensees' analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
requested amendments involve no significant hazards consideration.

Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
(1) Operation of the facility in accordance with the proposed
amendment would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The proposed amendments are administrative in nature and they do
not affect assumptions contained in plant safety analyses, the
physical design and/or operation of the plant, nor do they affect
Technical Specifications that preserve safety analysis assumptions.
These proposed changes do not change the existing administrative
controls on plant staff working hours. Any future changes to these
procedures will be controlled under established procedure control
processes that will ensure the administrative controls on work hours
remain effective. Further, the proposed changes do not alter the
design, function, or operation of any plant component. Therefore,
operation of the facility in accordance with the proposed amendments
would not involve a significant increase in the probability or
consequences of an accident previously evaluated.
(2) Operation of the facility in accordance with the proposed
amendment would not create the possibility of a new or different
kind of accident from any accident previously evaluated.
The changes being proposed are administrative in nature and do
not introduce a new mode of plant operation or surveillance
requirement, nor involve a physical modification to the plant.
Therefore, the design, function, or operation of any plant component
is not altered. The changes propose to relocate specific controls
for plant staff working hours from the TS to existing administrative
procedures. The specific controls for plant staff working hours are
described in these procedures and require a deliberate decision-
making process to manage the potential for impaired personnel
performance. Therefore, operation of the facility in accordance with
the proposed amendments would not create the possibility of a new or
different kind of accident from any accident previously evaluated.
(3) Operation of the facility in accordance with the proposed
amendment would not involve a significant reduction in a margin of
safety.
The proposed changes conform closely to the industry and NRC
approved TSTF-258 Rev. 4 and relate to the relocation of TS specific
working hour limits and controls to administrative procedures that
control working hours. The specific controls for working hours of
reactor plant staff are described in procedures that require a
deliberate decision-making process to manage the potential for
impaired personnel performance. Furthermore, any future changes to
these procedures will be controlled under established procedure
control processes that will ensure the administrative controls on
work hours remain effective. Therefore, operation of the facility in
accordance with the proposed amendments would not involve a
significant reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

St. Lucie Plant, Unit Nos. 1 and 2, St. Lucie County, Florida
Date of amendment request: January 25, 2002.
Description of amendment request: The proposed amendments would
revise the St. Lucie Plant, Units 1 and 2, Technical Specifications,
Appendix B, ``Environmental Protection Plan (Non-Radiological)'' to
incorporate the revised terms and conditions of the Incidental Take
Statement included in the Biological Opinion issued by the National
Marine Fisheries Service on May 4, 2001, as clarified by NMFS letter
dated October 8, 2001. These amendments also incorporate administrative
revisions necessary to change references to the National Pollutant
Discharge Elimination System Permit to the Wastewater Permit, based on
a change in administrative authority over these permits.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
(1) Operation of the facility in accordance with the proposed
amendments would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The changes are administrative in nature and would in no way
affect the initial conditions, assumptions, or conclusions of the
St. Lucie Unit 1 or Unit 2 accident analyses. In addition, the
proposed changes would not affect the operation or performance of
any equipment assumed in the accident analyses. Based on the above
information, we conclude that the proposed changes would not
significantly increase the probability or consequences of an
accident previously evaluated.
(2) Use of the modified specification would not create the
possibility of a new or different kind of accident from any
previously evaluated.
The changes are administrative in nature and would in no way
impact or alter the configuration or operation of the facilities and
would create no new modes of operation. We conclude that the
proposed changes would not create the possibility of a new or
different kind of accident.
(3) Use of the modified specification would not involve a
significant reduction in a margin of safety.
The changes are administrative in nature and would in no way
affect plant or equipment operation or the accident analysis. We
conclude that the proposed changes would not result in a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

St. Lucie Plant, Unit Nos. 1 and 2, St. Lucie County, Florida
Date of amendment request: January 25, 2002.
Description of amendment request: The proposed amendment would
revise Section 4.8.1.1.2.g.2 of the St. Lucie Units 1 and 2 Technical
Specifications (TS), which currently requires a test of the diesel fuel
oil system piping at elevated pressure once every 10 years. In lieu of
hydrostatic testing, the diesel fuel oil systems will be included in
the population of systems subjected to periodic system pressure testing
at normal operating conditions required by the American Society of
Mechanical Engineers Code for Class 3 systems in accordance with the
inservice inspection program.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
(1) Operation of the facility in accordance with the proposed
amendments would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The proposed amendments do not involve a significant increase in
the probability or consequences of an accident previously evaluated
because industry experience has shown that an inservice leak test
conducted at normal operating temperature and pressure is just as
effective at finding leakage as a hydrostatic test conducted at 110
percent of the design pressure. Therefore, there is no increase in
the probability or consequences of previously evaluated accidents.
Also, note that the diesel generator fuel oil system is not
specifically modeled in the St. Lucie probability safety assessment
(PSA). Based on the St. Lucie PSA, the diesel generator failure
probability is dominated by failure modes other than fuel oil pipe
rupture. The total diesel generator failure probability is on the
order of 1E-2, with the contribution from fuel oil pipe rupture on
the order of 1E-5 (i.e., three orders of magnitude below the EDG
[emergency diesel generator] failure probability).
(2) Operation of the facility in accordance with the proposed
amendments would not create the possibility of a new or different
kind of accident from any previously evaluated.
The use of the modified specifications can not create the
possibility of a new or different kind of accident from any
previously evaluated since the proposed amendments provide an
alternative method of leak detection for the required 10-year
inservice inspection. They do not result in an operational condition
different from that which has already been considered by TS.
Therefore, the changes do not create the possibility of a new or
different kind of accident or malfunction.
(3) Operation of the facility in accordance with the proposed
amendments would not involve a significant reduction in a margin of
safety.
The alternative method of leak detection has no impact on the
consequences of any analyzed accident and does not significantly
change the failure probability of equipment that provides protection
for the health and safety of the public. Therefore, there is no
significant decrease in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Nuclear Management Company, LLC, Docket No. 50-305, Kewaunee Nuclear
Power Plant, Kewaunee County, Wisconsin
Date of amendment request: January 14, 2002.
Description of amendment request: The proposed amendment would
revise the Kewaunee Nuclear Power Plant Technical Specifications (TS)
3.10.f, ``Inoperable Rod Position Indicator Channels,'' to provide an
allowed outage time (AOT) for the Individual Rod Position Indicator
(IRPI) system of 24 hours with more than one IRPI per group inoperable.
The TS did not previously have an explicit AOT for this condition. In
addition, the proposed amendment would reformat TS 3.10.f using
MicroSoft Word to more closely resemble the format of Improved Standard
Technical Specification (ISTS) to improve clarity.
[[Page 7420]]
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The format changes are administrative in nature and therefore
have no effect on the probability or consequences of an accident.
The Individual Rod Position Indicator (IRPI) System is not an
accident initiator. Therefore, any change to the system would not
effect the probability of an accident previously evaluated. The risk
of core damage/release of radioactivity would not increase with the
other reactor condition monitors still functional along with the
plant mode remaining the same.
The proposed changes provide more time to troubleshoot and
restore the system, which would keep the reactor in a steady state
condition, rather than to challenge the plant with a reduction in
power. The addition of hourly reactor temperature checks as well as
placing the rod controls to manual are added to temporarily increase
the surveillance on the reactor due to loss of the IRPI system
during the IRPI AOT. Since IRPI's are not an accident initiator and
compensatory measures have been added to ensure rod position is
known incase one or more IRPIs are inoperable, this amendment does
not involve an increase in the probability or consequences of an
accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
The format changes are administrative in nature and therefore
have no effect on the probability or consequences of a new or
different kind of accident from any accident previously evaluated.
The primary function of the IRPI system is to monitor the position
of each rod and send that information to the control room. A failure
of this system will not result in an accident.
The proposed changes do not involve a change to the physical
plant or operations. Operations currently monitors power tilt,
excore detectors, thermocouples, and rod movement when IRPIs become
inoperable. The extra surveillance requirements added by the ISTS
for the AOT are there to cover the loss of information when the
IRPIs are OOS. The change to 24 hours for troubleshooting when more
than one IRPI channel per group is inoperable would therefore not
create the possibility of a new or different kind of accident from
any accident previously evaluated.
3. Involve a significant reduction in the margin of safety.
The format changes are administrative in nature and therefore
are not involved in a significant reduction in the margin of safety.
Margin of safety relates to actual rod position in relation to each
other. This margin is controlled by rod misalignment requirements.
The IRPIs provide indication of that position which the operators
have other means of determining should the need arise. The
implementation of this proposed amendment ensures continued close
monitoring of rod position but also adds hourly documentation of the
reactor coolant temperature requirement as well. The proposed change
provides more time to troubleshoot and restore the system, which
would keep the reactor in a steady state condition, rather than to
challenge the plant with a reduction in power. Therefore, NMC
concludes that there is not a significant reduction in the margin of
safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Date of amendment request: January 28, 2002.
Description of amendment request: The proposed amendment would
revise the Core Operating Limits Report (COLR) analytical methods
referenced in Technical Specification (TS) 5.6.5.b. Specifically, the
changes would add references to two NRC-approved Framatome ANP, Inc.,
reports: (1) EMF-2310(P)(A), Revision 0, ``SRP [Standard Review Plan]
Chapter 15 Non-LOCA [loss-of-coolant accident] Methodology for

RELAP5 Based,'' dated March 2001. Existing references in TS 5.6.5.b
describing Exxon Nuclear Company's large-break LOCA evaluation model
would be deleted.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
Nuclear Management Company has evaluated whether or not a
significant hazards consideration is involved with the proposed
amendment by focusing on the three standards set forth in 10 CFR
50.92, ``Issuance of Amendment.'' The following evaluation supports
the finding that operation of the facility in accordance with the
proposed change would not:
1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed license amendment removes a safety analysis
methodology and adds two new safety analysis methodologies in TS
5.6.5.b. Accidents previously evaluated will be unaffected because
they will continue to be analyzed using applicable methodologies
approved by the Nuclear Regulatory Commission to ensure all required
safety limits are met. The proposed amendment does not affect the
acceptance criteria for loss-of-coolant accidents (LOCA) or non
loss-of-coolant accidents. As such, the proposed amendment does not
increase the probability or consequences of an accident. The
proposed amendment does not involve operation of the required
structures, systems or components (SSCs) in a manner or
configuration different from those previously recognized or
evaluated.
Therefore, operation of the facility in accordance with the
proposed amendment would not involve a significant increase in the
probability or consequences of an accident previously evaluated.
2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
The proposed amendment does not involve a physical alteration of
any SSC or a change in the way any SSC is operated. The proposed
amendment does not involve operation of any required SSCs in a
manner or configuration different from those previously recognized
or evaluated. No new failure mechanisms will be introduced by
changes being requested.
Thus, this change does not create the possibility of a new or
different kind of accident from any accident previously evaluated.
3. Involve a significant reduction in a margin of safety.
The proposed amendment does not, by itself, introduce a failure
mechanism. The proposed amendment does not involve any physical
changes to the plant or manner in which the plant was operated. The
proposed changes do not affect the acceptance criteria for loss-of-
coolant or non-loss-of-coolant accidents. All required safety limits
will continue to be analyzed using methodologies approved by the
Nuclear Regulatory Commission.
Therefore, the proposed amendment would not involve a
significant reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

PSEG Nuclear LLC, Docket No. 50-354, Hope Creek Generating Station,
Salem County, New Jersey
Date of amendment request: January 4, 2002.
Description of amendment request: The proposed amendment would add
Technical Specification (TS) 3/4.3.10, ``Mechanical Vacuum Pump Trip
Instrumentation.''
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration. The NRC staff's review is presented below:
(1) Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
No. The proposed amendment would add a new TS section for the
instrumentation that provides the automatic tripping of the
mechanical vacuum pumps when high radiation is detected in the main
steamlines. The proposed change has no effect on any structures,
systems, or components (SSCs) since the mechanical vacuum pump
automatic trip function is already part of the existing plant
design. The new TS requirements are being added because automatic
tripping of the mechanical vacuum pumps is credited for mitigating
the radiological consequences of a control rod drop accident (CRDA),
and, as such, a TS LCO must be established to meet the requirements
stated in 10 CFR 50.36(c)(2)(ii), Criterion 3. Since the proposed
change only establishes TS requirements for an existing function,
and there are no effects to any SSCs, there is no impact on the CRDA
analysis. Therefore, the proposed change does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
(2) Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
No. The proposed amendment does not change the design function
or operation of any SSCs. Plant operation will not be affected by
the proposed change and no new failure mechanisms, malfunctions, or
accident initiators will be created. Therefore, the proposed change
does not create the possibility of a new or different kind of
accident from any previously evaluated.
(3) Does the proposed change involve a significant reduction in
a margin of safety?
No. The proposed amendment only establishes TS requirements for
an existing function and will not change any plant operating
parameters. The licensee's submittal stated that the proposed change
does not affect the radiological consequences for a CRDA. Therefore,
the proposed change does not involve a significant reduction in a
margin of safety.
Based on this review, it appears that the three standards of 10 CFR
50.92(c) are satisfied. Therefore, the NRC staff proposes to determine
that the amendment request involves no significant hazards
consideration.

Date of amendment requests: March 21, 2001 as superseded by letter
dated October 24, 2001.
Description of amendment requests: The proposed amendments would
revise Technical Specification (TS) 5.5.2.12 pertaining to ventilation
filter testing program (VFTP). Specifically, the proposed amendments
would: (a) in TS 5.5.2.12 lead paragraph, and TS 5.5.2.12d, delete
reference to Regulatory Guide (RG) 1.52 and American Society of
Mechanical Engineers (ASME) N510-1989; the testing frequency will

5.5.2.12a and TS 5.5.2.12b, refer to American National Standards
Institute (ANSI) Code N510-1975 instead of ASME N510-1989, and add a
note to provide clarification regarding high energy particulate air
(HEPA) filter qualification and testing methodology; and (c) in TS
5.5.2.12c, include specific temperature and relative humidity for
laboratory testing of charcoal adsorber samples.
The October 24, 2001, submittal supercedes in its entirety the
licensee's March 21, 2001, submittal which was previously noticed in
the Federal Register on April 18, 2001.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
(1) Will operation of the facility in accordance with this
proposed change involve a significant increase in the probability or
consequences of an accident previously evaluated?
Response: No.
The proposed change is to change the reference to ASME Code in
subsection 5.5.2.12.a and 5.5.2.12.b from ASME N510-1989 to ANSI
N510-1975. Technical Specification (TS) 3.7.11, ``Control Room
Emergency Air Cleanup System'' (CREACUS), Surveillance Requirement
(SR) 3.7.11.2 and TS 3.7.14, ``Fuel Handling Building Post-Accident
Cleanup Filter System'' (PACU), SR 3.7.14.2 requires CREACUS and
PACU filter testing in accordance with the Ventilation Filter
Testing Program (VFTP).
SONGS [San Onofre Nuclear Generating Station] TS 5.5.12.a,
``Ventilation Filter Testing Program,'' states that the in-place
HEPA filter testing is performed in accordance with RG 1.52,
Revision 2 and ASME N510-1989. The discrepancy arises because the
HEPA filter testing method used at SONGS does not entirely meet the
methodology which are delineated in ASME N510-1989. In particular,
the CREACUS in-place HEPA filter testing uses a method (Alternate
Shroud Test) which is no longer specified in ASME N510-1989. But
this method is specified in ANSI N510-1975 and was used when the
plant was licensed. In addition, the PACU in-place HEPA filter
testing methodology which is employed at SONGS, has a downstream
point location which differs from the location suggested in ASME
N510-1989.
ANSI N510-1975, while providing a suggestion where downstream
sample could be located, nevertheless does not provide a specific
location. The test acceptance criteria are the same for methods
cited in ANSI N510-1975 and ASME N510-1989. The method which is
employed at SONGS provides more conservative results because the
test is performed on individual HEPA filters, which ensures that
each of the HEPA filters in the tested bank meets the acceptance
criteria, as compared to the method suggested in ASME N510-1989.
The locations of the PACU HEPA downstream sample points are
different from the locations suggested in ASME N510-1989, though
they meet the requirements delineated in ANSI N510-1975. ANSI N510-
1975 requires that a single representative downstream sample point
be established, if possible, at the location where adequate mixing
may be achieved, or at a point downstream of a fan, or multiple
downstream sampling points may be used (such as in the Alternate
Shroud Technique used in the CREACUS system) if a single downstream
sample point is not feasible.
Since the HEPA filters are tested to the same acceptance
criteria, and the testing methodology is permitted by ANSI N510-
1975, to which the plant was licensed, it is concluded, that the
proposed change will not involve a significant increase in the
probability or consequences of an accident previously evaluated.
Section 5.5.2.12.c will be modified by specifying the
temperature and relative humidity for laboratory testing of charcoal
adsorber samples. This modification clarifies that samples shall be
obtained in accordance with RG 1.52, Revision 2, and tested per
methodology of ASTM D3803-1989, at 30'C and relative humidity of
70%. This clarification eliminates possible misinterpretation of the
current wording.
The proposed change will also include Note 1 which clarifies the
inplace testing of charcoal adsorbers and HEPA filters. Based on the
provisions of section 10.4 of ASME N510-1989, this Note allows
replacement of DOP [dioctyl phthalate] with a suitable alternate.
The proposed change also clarifies the statement of subsection
5.5.2.12.d. Pressure drop testing across combined HEPA filters, the
prefilters, and the charcoal adsorbers is
[[Page 7422]]
industry-wide practice which is based on good engineering practice
and operating experience. This change will not increase the
probability or consequences of an accident previously evaluated.
Therefore, the probability or consequences of an accident
previously evaluated will not be increased by operating the facility
in accordance with this proposed change.
(2) Will operation of the facility in accordance with this
proposed change create the possibility of a new or different kind of
accident from any accident previously evaluated?
Response: No.
The proposed change does not change the design or configuration
of the plant. The proposed change is to change the reference to ASME
Code in subsection 5.5.2.12.a and 5.5.2.12.b from ASME N510-1989 to
ANSI N510-1975 to reflect the standard used. Section 5.5.2.12.c will
be modified by specifying the temperature and relative humidity for
laboratory testing of charcoal adsorber samples. This is done for
clarification purposes. Also, subsection 5.5.2.12.d will be changed
by deleting the references to RG 1.52, Revision 2, and ASME N510-
1989 regarding pressure drop test across HEPA filters. RG 1.52,
Revision 2 and ASME N510-1989 do not require pressure drop test[ing]
across HEPA filters.
Therefore, this proposed change will not create the possibility
of a new or different kind of accident from any accident that has
been previously evaluated.
(3) Will operation of the facility in accordance with this
proposed change involve a significant reduction in a margin of
safety?
Response: No.
The proposed change is to change the reference to ASME Code in
subsections 5.5.2.12.a, and 5.5.2.12.b from ASME N510-1989 to ASME
N510-1975. The CREACUS units HEPA filters are currently tested to
N510-1975. Although the test methodology is slightly different than
that in N510-1989, the acceptance criteria are the same and the
current methodology is conservative. Thus the current testing
satisfies the acceptance criteria of N510-1989, even though the test
method is different. Section 5.5.2.12.c will be clarified by
specifying the temperature and relative humidity for laboratory
testing of charcoal adsorber samples.
The current methodology for HEPA filter testing will not change
as a result of the proposed change. Also, deletion of references to
RG 1.52, Revision 2 and ASME N510-1989 from subsection 5.5.2.12.d
clarifies this section because these standards do not require HEPA
filters pressure drop test. Consequently, there is no change to the
design or operation of the plant as a result of this change.
Therefore, the operation of the facility in accordance with this
proposed change will not involve a significant reduction in a margin
of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.
