NUCLEAR REGULATORY COMMISSION
[NRC-2009-0456]
Biweekly Notice; Applications and Amendments to Facility
Operating Licenses Involving No Significant Hazards Considerations
I. Background
Pursuant to section 189a.(2) of the Atomic Energy Act of 1954, as
amended (the Act), the U.S. Nuclear Regulatory Commission (the
Commission or NRC) is publishing this regular biweekly notice. The Act
requires the Commission publish notice of any amendments issued, or
proposed to be issued and 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 September 24, 2009, to October 7, 2009. The
last biweekly notice was published on October 6, 2009 (74 FR 51327).
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 Title 10 of the Code of Federal
Regulations (10 CFR), Section 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 60 days after the date of publication of this notice. The
Commission may issue the license amendment before expiration of the 60-
day period provided that its final determination is that the amendment
involves no significant hazards consideration. In addition, the
Commission may issue the amendment prior to the expiration of the 30-
day comment period should circumstances change during the 30-day
comment period such that failure to act in a timely way would result,
for example in derating or shutdown of the facility. Should the
Commission take action prior to the expiration of either the comment
period or the notice period, it will publish in the Federal Register a
notice of issuance. Should the Commission make a final No Significant
Hazards Consideration Determination, any hearing will take place 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, Rulemaking
and Directives Branch (RDB), TWB-05-B01M, 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 faxed to the RDB at 301-492-3446. Documents may be examined, and/or
copied for a fee, at the NRC's Public Document Room (PDR), located at
One White Flint North, Public File Area O1F21, 11555 Rockville Pike
(first floor), Rockville, Maryland.
Within 60 days after the date of publication of this notice, any
person(s) whose interest may be affected by this action may file a
request for a hearing and a petition to intervene with respect to
issuance of the amendment to the subject facility operating license.
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 person(s)
should consult a current copy of 10 CFR 2.309, which is available at
the Commission's PDR, located at One White Flint North, Public File
Area O1F21, 11555 Rockville Pike (first floor), Rockville, Maryland.
Publicly available records will be accessible from the Agencywide
Documents Access and Management System's (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 a
presiding officer designated by the Commission or by the Chief
Administrative Judge of the Atomic Safety and Licensing Board Panel,
will rule on the request and/or petition; and the Secretary or the
Chief Administrative Judge of the Atomic Safety and Licensing Board
will issue a notice of a hearing or an appropriate order.
As required by 10 CFR 2.309, 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 general requirements: (1) The name, address, and telephone
number of the requestor or petitioner; (2) the nature of the
requestor's/petitioner's right under the Act to be made a party to the
proceeding; (3) the nature and extent of the requestor's/petitioner's
property, financial, or other interest in the proceeding; and (4) the
possible effect of any decision or order which may be entered in the
proceeding on the requestor's/petitioner's interest. The petition must
also identify the specific contentions which the petitioner/requestor
seeks to have litigated at the proceeding.
Each contention must consist of a specific statement of the issue
of law or fact to be raised or controverted. In addition, the
petitioner/requestor shall provide a brief explanation of the bases for
the contention and a concise statement of the alleged facts or expert
opinion which support the contention and on which the petitioner/
requestor intends to rely in proving the contention at the hearing. The
petitioner/requestor must also provide references to those specific
sources and documents of which the petitioner is aware and on which the
petitioner/requestor intends to rely to establish those facts or expert
opinion. The petition must include 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/requestor to relief. A petitioner/
requestor who fails to satisfy 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
[[Page 53775]]
participate fully in the conduct of the hearing.
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.
All documents filed in NRC adjudicatory proceedings, including a
request for hearing, a petition for leave to intervene, any motion or
other document filed in the proceeding prior to the submission of a
request for hearing or petition to intervene, and documents filed by
interested governmental entities participating under 10 CFR 2.315(c),
must be filed in accordance with the NRC E-Filing rule, which the NRC
promulgated in August 28, 2007 (72 FR 49139). The E-Filing process
requires participants to submit and serve all adjudicatory documents
over the internet, or in some cases to mail copies on electronic
storage media. Participants may not submit paper copies of their
filings unless they seek an exemption in accordance with the procedures
described below.
To comply with the procedural requirements of E-Filing, at least
ten (10) days prior to the filing deadline, the petitioner/requestor
should contact the Office of the Secretary by e-mail at
[email protected], or by calling (301) 415-1677, to request (1) a
digital ID certificate, which allows the participant (or its counsel or
representative) to digitally sign documents and access the E-Submittal
server for any proceeding in which it is participating; and/or (2)
creation of an electronic docket for the proceeding (even in instances
in which the petitioner/requestor (or its counsel or representative)
already holds an NRC-issued digital ID certificate). Each petitioner/
requestor will need to download the Workplace Forms ViewerTM
to access the Electronic Information Exchange (EIE), a component of the
E-Filing system. The Workplace Forms ViewerTM is free and is
available at http://www.nrc.gov/site-help/e-submittals/install-viewer.html. Information about applying for a digital ID certificate is
available on NRC's public Web site at http://www.nrc.gov/site-help/e-submittals/apply-certificates.html.
Once a petitioner/requestor has obtained a digital ID certificate,
had a docket created, and downloaded the EIE viewer, it can then submit
a request for hearing or petition for leave to intervene. Submissions
should be in Portable Document Format (PDF) in accordance with NRC
guidance available on the NRC public Web site at http://www.nrc.gov/site-help/e-submittals.html. A filing is considered complete at the
time the filer submits its documents through EIE. To be timely, an
electronic filing must be submitted to the EIE system no later than
11:59 p.m. Eastern Time on the due date. Upon receipt of a
transmission, the E-Filing system time-stamps the document and sends
the submitter an e-mail notice confirming receipt of the document. The
EIE system also distributes an e-mail notice that provides access to
the document to the NRC Office of the General Counsel and any others
who have advised the Office of the Secretary that they wish to
participate in the proceeding, so that the filer need not serve the
documents on those participants separately. Therefore, applicants and
other participants (or their counsel or representative) must apply for
and receive a digital ID certificate before a hearing request/petition
to intervene is filed so that they can obtain access to the document
via the E-Filing system.
A person filing electronically using the agency's adjudicatory e-
filing system may seek assistance through the ``Contact Us'' link
located on the NRC Web site at http://www.nrc.gov/site-help/e-submittals.html or by calling the NRC Meta-System Help Desk, which is
available between 8 a.m. and 8 p.m., Eastern Time, Monday through
Friday, excluding government holidays. The Meta-System Help Desk can be
contacted by telephone at 1-866-672-7640 or by e-mail at
[email protected].
Participants who believe that they have a good cause for not
submitting documents electronically must file an exemption request, in
accordance with 10 CFR 2.302(g), with their initial paper filing
requesting authorization to continue to submit documents in paper
format. Such filings must be submitted by: (1) First class mail
addressed to the Office of the Secretary of the Commission, U.S.
Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention:
Rulemaking and Adjudications Staff; or (2) courier, express mail, or
expedited delivery service to the Office of the Secretary, Sixteenth
Floor, One White Flint North, 11555 Rockville Pike, Rockville,
Maryland, 20852, Attention: Rulemaking and Adjudications Staff.
Participants filing a document in this manner are responsible for
serving the document on all other participants. Filing is considered
complete by first-class mail as of the time of deposit in the mail, or
by courier, express mail, or expedited delivery service upon depositing
the document with the provider of the service.
Non-timely requests and/or petitions and contentions will not be
entertained absent a determination by the Commission, the presiding
officer, or the Atomic Safety and Licensing Board that the request and/
or petition should be granted and/or the contentions should be
admitted, based on a balancing of the factors specified in 10 CFR
2.309(c)(1)(i)-(viii).
Documents submitted in adjudicatory proceedings will appear in
NRC's electronic hearing docket which is available to the public at
http://ehd.nrc.gov/EHD_Proceeding/home.asp, unless excluded pursuant
to an order of the Commission, an Atomic Safety and Licensing Board, or
a Presiding Officer. Participants are requested not to include personal
privacy information, such as social security numbers, home addresses,
or home phone numbers in their filings, unless an NRC regulation or
other law requires submission of such information. With respect to
copyrighted works, except for limited excerpts that serve the purpose
of the adjudicatory filings and would constitute a Fair Use
application, participants are requested not to include copyrighted
materials in their submissions.

Entergy Gulf States Louisiana, LLC, and Entergy Operations, Inc.,
Docket No. 50-458, River Bend Station (RBS), Unit 1, West Feliciana
Parish, Louisiana
Date of amendment request: August 10, 2009.
Description of amendment request: The proposed amendment would
revise the RBS Technical Specifications (TSs) to support operation with
24-month fuel cycles. Specifically, the change addresses certain TS
Surveillance Requirement (SR) frequencies that are specified as ``18
months'' by revising them to ``24 months'' in accordance with the
guidance of U.S. Nuclear Regulatory Commission (NRC) Generic Letter 91-
04, ``Changes in Technical Specification Surveillance Intervals to
Accommodate a 24-Month Fuel Cycle,'' dated April 2, 1991.
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 amendment involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed TS changes involve a change in the surveillance
testing intervals and allowable values to facilitate a change in the
operating cycle length. The proposed TS changes do not physically
impact the plant. The proposed TS changes do not degrade the
performance of, or increase the challenges to, any safety systems
assumed to function in the accident analysis. The proposed TS
changes do not impact the usefulness of the SRs in evaluating the
operability of required systems and components, or the way in which
the surveillances are performed. In addition, the frequency of
surveillance testing is not considered an initiator of any analyzed
accident, nor does a revision to the frequency introduce any
accident initiators. The specific value of the allowable value is
not considered an initiator of any analyzed accident. Therefore, the
proposed change does not involve a significant increase in the
probability of an accident previously evaluated.
The consequences of a previously evaluated accident are not
significantly increased. The proposed change does not affect the
performance of any equipment credited to mitigate the radiological
consequences of an accident. Evaluation of the proposed TS changes
demonstrated that the availability of credited equipment is not
significantly affected because of other more frequent testing that
is performed, the availability of redundant systems and equipment,
and the high reliability of the equipment. Historical review of
surveillance test results and associated maintenance records did not
find evidence of failures that would invalidate the above
conclusions.
The allowable values have been developed in accordance with [NRC
Regulatory Guide] 1.105, ``Instrument Setpoints,'' to ensure that
the design and safety analysis limits are satisfied. The methodology
used for the development of the allowable values ensures the
affected instrumentation remains capable of mitigating design basis
events as described in the safety analyses and that the results and
radiological consequences described in the safety analyses remain
bounding. Therefore, the proposed change does not alter the ability
to detect and mitigate events and, as such, does not involve a
significant increase in the consequences of an accident previously
evaluated.
Standby Liquid Control System
The proposed change in required weight of Boron-10 in [standby
liquid control (SLC)] does not physically impact the plant, nor does
it degrade the performance of, or increase the challenges to, any
safety systems assumed to function in the accident analysis. The
consequences of a previously evaluated accident are not increased.
The proposed change does not affect the performance of any equipment
credited to mitigate the radiological consequences of an accident.
Evaluation of the proposed TS changes demonstrated that the
availability of credited equipment is not affected. Therefore, the
proposed change does not alter the ability to detect and mitigate
events and, as such, does not involve a significant increase in the
consequences of an accident previously evaluated.
Loss of Power Instrumentation
A change to the Allowable Values (AVs) is proposed for Table
3.3.8.1-1, Item 1.c and Item 2.c. The proposed change is the result
of application of the RBS Instrument Setpoint Methodology using
plant-specific drift values and incorporating margins available
based on a revised off-site reliability study. Application of this
methodology results in AVs that more accurately reflect total device
accuracy, as well as that of test equipment and calculated drift
between surveillances. The proposed change will not result in any
hardware changes. The instrumentation is not assumed to be an
initiator of any analyzed event. Existing operating margin between
plant conditions and actual plant setpoints is not significantly
reduced due to the proposed changes. The role of the instrumentation
is in mitigating and thereby, limiting the consequences of
accidents.
The AVs were developed to ensure the design and safety analysis
limits are satisfied. The methodology used for the development of
the AVs ensures that: (1) The affected instrumentation remains
capable of mitigating design basis events as described in the safety
analysis, and (2) the results and radiological consequences
described in the safety analysis remain bounding. Additionally, the
proposed change does not alter the plant's ability to detect and
mitigate events. Therefore, this change does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
The change in the degraded voltage protection voltage AVs allows
the protection scheme to function as originally designed. The
proposed allowable values ensure that the Class 1E distribution
system remains connected to the offsite power system when adequate
offsite voltage is available and motor starting transients are
considered.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
The proposed TS changes involve a change in the surveillance
testing intervals and allowable values to facilitate a change in the
operating cycle length. The proposed TS changes do not introduce any
failure mechanisms of a different type than those previously
evaluated, since there are no physical changes being made to the
facility. No new or different equipment is being installed. No
installed equipment is being operated in a different manner. As a
result, no new failure modes are being introduced. The way
surveillance tests are performed remains unchanged. A historical
review of surveillance test results and associated maintenance
records indicated there was no evidence of any failures that would
invalidate the above conclusions.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
Standby Liquid Control System
The proposed change to the required weight of Boron-10 in SLC
does not introduce any failure mechanisms of a different type than
those previously evaluated, since there are no physical changes
being made to the facility. No new or different equipment is being
installed. No installed equipment is being operated in a different
manner. As a result, no new failure modes are being introduced. The
way surveillance tests are performed remains unchanged. A historical
review of surveillance test results and associated maintenance
records indicated there was no evidence of any failures that would
invalidate the above conclusions.
Loss of Power Instrumentation
The proposed change in AVs is the result of application of the
Instrument Setpoint Methodology using plant-specific drift values
and does not create the possibility of a new or different kind of
accident from any accident previously evaluated. This is based upon
the fact that the method and manner of plant operation are
unchanged.
The use of the proposed AVs does not impact safe operation of
the plant in that the safety analysis limits are maintained. The
proposed change in AVs involves no system additions. The AVs are
revised to ensure the affected instrumentation remains capable of
mitigating accidents and transients. Plant equipment will not be
operated in a manner different from previous operation, except that
setpoints may be changed. No additional failure mechanisms are
introduced as a result of the changes to the allowable values. Since
operational methods remain unchanged and
[[Page 53777]]
the operating parameters were evaluated to maintain the plant within
existing design basis criteria, no different type of failure or
accident is 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 amendment involve a significant reduction
in a margin of safety?
Response: No.
The proposed TS changes involve a change in the surveillance
testing intervals and allowable values to facilitate a change in the
operating cycle length. The impact of these changes on system
availability is not significant, based on other more frequent
testing that is performed, the existence of redundant systems and
equipment, and overall system reliability. Evaluations have shown
there is no evidence of time dependent failures that would impact
the availability of the systems. The proposed changes do not
significantly impact the condition or performance of structures,
systems, and components relied upon for accident mitigation. The
proposed changes in TS instrumentation allowable values are the
result of application of the RBS setpoint methodology using plant
specific drift values. The revised allowable values more accurately
reflect total instrumentation loop accuracy including drift while
continuing to protect any assumed analytical limit. The proposed
changes do not result in any hardware changes or in any changes to
the analytical limits assumed in accident analyses. Existing
operating margin between plant conditions and actual plant setpoints
is not significantly reduced due to these changes. The proposed
changes do not significantly impact any safety analysis assumptions
or results.
Standby Liquid Control System
The proposed change in required weight of Boron-10 in SLC is to
facilitate a change in the operating cycle length. The proposed
change does not result in any hardware changes or in any changes to
the analytical limits assumed in accident analyses. Existing
operating margin between plant conditions and actual plant setpoints
is not reduced due to this change. The proposed change does not
impact any safety analysis assumptions or results. Therefore, the
proposed change does not involve a significant reduction in a margin
of safety.
Loss of Power Instrumentation
The proposed protection voltage AVs are low enough to prevent
inadvertent power supply transfer, but high enough to ensure that
sufficient voltage is available to the required equipment. The
proposed change does not involve a reduction in a margin of safety.
The proposed change was developed using a methodology to ensure
safety analysis limits are not exceeded. As such, this proposed
change does not involve a significant reduction in a 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.

Entergy Nuclear Operations, Inc., Docket No. 50-255, Palisades Nuclear
Plant, Van Buren County, Michigan
Date of amendment request: August 25, 2009.
Description of amendment request: The proposed amendment would
allow for a one-time extension to the ten-year frequency for the next
Palisades Nuclear Plant (PNP) containment Type A integrated leak rate
test (ILRT) that is required by Technical Specification (TS) 5.5.14.
The proposed change would permit the existing ILRT frequency to be
extended from ten years to approximately 11.25 years.
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 exemption involves a one-time extension to the
current interval for Type A containment testing. The current test
interval of 120 months (10 years) would be extended on a one-time
basis to no longer than approximately 135 months from the last Type
A test. The proposed extension does not involve either a physical
change to the plant or a change in the manner in which the plant is
operated or controlled. The containment is designed to provide an
essentially leak tight barrier against the uncontrolled release of
radioactivity to the environment for postulated accidents. As such,
the containment and the testing requirements invoked to periodically
demonstrate the integrity of the containment exist to ensure the
plant's ability to mitigate the consequences of an accident, and do
not involve the prevention or identification of any precursors of an
accident. Therefore, this proposed extension does not involve a
significant increase in the probability of an accident previously
evaluated.
This proposed extension is for the Type A containment leak rate
tests only. The Type B and C containment leak rate tests would
continue to be performed at the frequency currently required by the
PNP TS. As documented in NUREG 1493, Type B and C tests have
identified a very large percentage of containment leakage paths and
that the percentage of containment leakage paths that are detected
only by Type A testing is very small. The PNP Type A test history
supports this conclusion.
The integrity of the containment is subject to two types of
failure mechanisms that can be categorized as (1) activity based and
(2) time based. Activity based failure mechanisms are defined as
degradation due to system and/or component modifications or
maintenance. Local leak rate test requirements and administrative
controls such as configuration management and procedural
requirements for system restoration ensure that containment
integrity is not degraded by plant modifications or maintenance
activities. The design and construction requirements of the
containment combined with the containment inspections performed in
accordance with ASME Section XI, the Maintenance Rule, and TS
requirements serve to provide a high degree of assurance that the
containment would not degrade in a manner that is detectable only by
a Type A test. Based on the above, the proposed extension does not
involve a significant increase in the 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 revision to the TS involves a one-time extension to
the current interval for Type A containment testing. The containment
and the testing requirements invoked to periodically demonstrate the
integrity of the containment exist to ensure the plant's ability to
mitigate the consequences of an accident and do not involve the
prevention or identification of any precursors of an accident. The
proposed TS change does not involve a physical change to the plant
or the manner in which the plant is operated or controlled.
Therefore, the proposed TS change does not create the possibility of
a new or different kind of accident from any accident previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The proposed change to the TS involves a one-time extension to
the current interval for Type A containment testing. The proposed TS
change does not involve a physical change to the plant or a change
in the manner in which the plant is operated or controlled. The
specific requirements and conditions of the TS Containment Leak Rate
Testing Program exist to ensure that the degree of containment
structural integrity and leak-tightness that is considered in the
plant safety analysis is maintained. The overall containment leak
rate limit specified by TS is maintained. The proposed change
involves only the extension of the interval between Type A
containment leak rate tests. The proposed surveillance interval
extension is bounded by the 15-month extension currently authorized
within NEI 94-01, Revision 0. Type B and C containment leak
[[Page 53778]]
rate tests would continue to be performed at the frequency currently
required by TS. Industry experience supports the conclusion that
Type B and C testing detects a large percentage of containment
leakage paths and that the percentage of containment leakage paths
that are detected only by Type A testing is small. The containment
inspections performed in accordance with ASME Section XI and the
Maintenance Rule serve to provide a high degree of assurance that
the containment would not degrade in a manner that is detectable
only by Type A testing. The combination of these factors ensures
that the margin of safety in the plant safety analysis is
maintained. The design, operation, testing methods and acceptance
criteria for Type A, B, and C containment leakage tests specified in
applicable codes and standards would continue to be met, with the
acceptance of this proposed change, since these are not affected by
changes to the Type A test interval. Therefore, the proposed TS
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 Nuclear Vermont Yankee, LLC and Entergy Nuclear Operations,
Inc., Docket No. 50-271, Vermont Yankee Nuclear Power Station, Vernon,
Vermont
Date of amendment request: August 26, 2009.
Description of amendment request: The proposed amendment would
revise the Technical Specification (TS) Section 6.5 that governs
administrative controls of High Radiation Areas (HRA) to incorporate
the HRA administrative controls contained within the Standard Technical
Specifications, NUREG-1433, Revision 3.
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 operation of Vermont Yankee Nuclear Power Station (VY) in
accordance with the proposed amendment will not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
The proposed amendment does not impact the operability of any
structure, system or component that affects the probability of an
accident or that supports mitigation of an accident previously
evaluated. The proposed amendment does not affect reactor operations
or accident analysis and has no radiological consequences. The
operability requirements for accident mitigation systems remain
consistent with the licensing and design basis. Therefore, the
proposed amendment does not involve a significant increase in the
probability or consequences of an accident previously evaluated.
2. The operation of VY in accordance with the proposed amendment
will not create the possibility of a new or different kind of
accident from any accident previously evaluated.
The proposed amendment does not change the design or function of
any component or system. No new modes of failure or initiating
events are being introduced. Therefore, operation of VY in
accordance with the proposed amendment will not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. The operation of VY in accordance with the proposed amendment
will not involve a significant reduction in a margin of safety.
The proposed amendment does not change the design or function of
any component or system. The proposed amendment does not involve any
safety limits, safety settings or safety margins. The TS
administrative access controls for high radiation areas are being
replaced with those contained in section 5.7 of NUREG-1433 to
provide additional requirements and options for the control of these
areas.
Therefore, operation of VY in accordance with the proposed
amendment will not involve a significant reduction in the margin to
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.

Nine Mile Point Nuclear Station, LLC (NMPNS) Docket No. 50-410, Nine
Mile Point Nuclear Station Unit No. 2 (NMP 2), Oswego County, New York
Date of amendment request: May 27, 2009, as supplemented on August
28, 2009.
Description of amendment request: The proposed amendment requests
an increase in the maximum steady-state power level at NMP2 from 3467
megawatts thermal (MWt) to 3988 MWt. This represents a 15-percent
increase over the current licensed thermal power.
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 amendment] involve a significant increase
in the probability or consequences of an accident previously
evaluated?
No, the increase in power level discussed herein will not
significantly increase the probability or consequences of an
accident previously evaluated.
The proposed change will increase NMP2's authorized maximum
power level from the current licensed thermal power (CLTP) level of
3467 megawatts thermal (MWt) to 3988 MWt. In support of this
Constant Pressure Extended Power Uprate (CPPU), a comprehensive
evaluation was performed for nuclear steam supply system (NSSS) and
balance of plant (BOP) systems, structures, components, and analyses
that could be affected by this change. The effect of increasing the
maximum power level from the CLTP of 3467 MWt to 3988 MWt on the
NMP2 licensing and design bases was evaluated. The result of this
evaluation is that all plant components, as modified, will continue
to be capable of performing their design function at an uprated core
power of 3988 MWt. In addition, an evaluation of the accident
analyses concludes that applicable analysis acceptance criteria
continue to be met. Power level is an input assumption to the
equipment design and accident analyses, but it is not an initiator
for any transient or accident. Therefore, no accident initiators are
affected by this uprate and no challenges to any plant safety
barriers are created by this change.
Therefore, operation of the facility in accordance with the
proposed change does not involve a significant increase in the
probability of an accident previously evaluated.
This change does not affect the release paths, the frequency of
release, or the source term for release for any accidents previously
evaluated in the Updated Safety Analysis Report (USAR). Structures,
systems, and components (SSC) required to mitigate transients remain
capable of performing their design functions, and thus were found
acceptable. The source terms used to assess radiological
consequences have been reviewed and determined to bound operation at
the uprated condition. The results of EPU [extended power uprate]
accident evaluations do not exceed the U. S. Nuclear Regulatory
Commission (NRC) approved acceptance limits.
The spectrum of postulated accidents and transients has been
investigated and are shown to meet the regulatory criteria to which
NMP2 is currently licensed. In the area of fuel and core design, the
Safety Limit Minimum Critical Power ratio (SLMCPR) and other
applicable Specified Acceptable Fuel Design Limits (SAFDLS) are
still met. Continued compliance with the SLMCPR and other SAFDLs is
confirmed on a cycle specific basis consistent with criteria
accepted by the NRC.
Challenges to the reactor coolant pressure boundary were
evaluated at EPU conditions
[[Page 53779]]
(pressure, temperature, flow, and radiation) and found to meet the
acceptance criteria for allowable stresses. Adequate overpressure
margin is maintained.
Challenges to the containment have been evaluated and the
containment and its associated cooling system continue to meet
applicable regulatory requirements. The increase in the calculated
post Loss of Coolant Accident (LOCA) suppression pool temperature
above the current peak temperature was evaluated and determined to
be acceptable.
Radiological release events (accidents) have been evaluated and
shown to meet the requirements of 10 CFR 50.67.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. [Does the proposed amendment] create the possibility of a new
or different kind of accident from any accident previously
evaluated?
No, the increase in power level discussed herein will not create
the possibility of a new or different kind of accident from any
accident previously evaluated.
The proposed change will increase NMP2's authorized maximum
power level from the CLTP level of 3467 MWt to 3988 MWt. Equipment
that could be affected by EPU has been evaluated. No new operating
mode, safety-related equipment lineup, accident scenario, or
equipment failure mode was identified. The full spectrum of accident
considerations has been evaluated and no new or different kind of
accident has been identified. This Constant Pressure Extended Power
Uprate utilizes a standard evaluation methodology applied to known
technology employed within the range of current or modified plant
capabilities. As such, the plant safety-related equipment continues
to operate in accordance with regulatory criteria. Evaluations were
performed using NRC approved codes, standards and methods. No new
accidents or event precursors have been identified.
All structures, systems and components previously required for
the mitigation of a transient remain capable of fulfilling their
intended design functions. The proposed changes do not adversely
affect safety-related systems or components and do not challenge the
performance or integrity of any safety-related system. This change
does not adversely affect any current system interfaces or create
any new interfaces that could result in an accident or malfunction
of a different kind than was previously evaluated. Operating at a
core power level of 3988 MWt does not create any new accident
initiators or precursors.
Therefore, the proposed changes do not create the possibility of
a new or different kind of accident from any accident previously
evaluated.
3. [Does the proposed amendment] involve a significant reduction
in a margin of safety?
No, the increase in power level discussed herein will not
involve a significant reduction in a margin of safety.
Comprehensive analyses of the proposed changes have concluded
that relevant design and safety acceptance criteria will be met
without a significant reduction in margins of safety. The analyses
supporting EPU have demonstrated that the NMP2 SSCs are capable of
safely performing at EPU conditions. The analyses identified and
defined the major input parameters to the NSSS, analyzed NSSS design
transients, and evaluated the capabilities of the NSSS fluid
systems, NSSS/BOP interfaces, NSSS control systems, and NSSS and BOP
components, as appropriate. Radiological consequences of design
basis events remain within regulatory limits and are not increased
significantly. The analyses confirmed that NSSS and BOP SSCs are
capable, some with modifications, of achieving EPU conditions
without significant reduction in margins of safety.
Analyses have shown that the integrity of primary fission
product barriers will not be significantly affected as a result of
the power increase. Calculated loads on SSCs important to safety
have been shown to remain within design allowables under EPU
conditions for all design basis event categories. Plant response to
transients and accidents do not result in exceeding acceptance
criteria. As appropriate, the evaluations that demonstrate
acceptability of EPU have been performed using methods that have
either been reviewed and approved by the NRC staff, or that are in
compliance with regulatory review guidance and standards established
for maintaining adequate margins of safety. These evaluations
demonstrate that there are no significant reductions in the margins
of safety.
Maximum power level is one of the inherent inputs that determine
the safe operating range defined by the accident analyses. The
Technical Specifications ensure that NMP2 is operated within the
bounds of the inputs and assumptions used in the accident analyses.
The acceptance criteria for the accident analyses are conservative
with respect to the operating conditions defined by the Technical
Specifications. The engineering reviews performed for the constant
pressure extended power uprate confirm that the accident analyses
criteria are met at the revised maximum allowable thermal power
level of 3988 MWt, as well as at the rated thermal power (RTP)
levels specified in the Facility Operating License and Technical
Specifications. Therefore, the adequacy of the revised Facility
Operating Licenses and Technical Specifications to maintain the
plant in a safe operating range is also confirmed, and the increase
in maximum allowable power level does not involve a significant
decrease in a margin of safety.
Therefore, the proposed changes do 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.

Nine Mile Point Nuclear Station, LLC (NMPNS) Docket No. 50-410, Nine
Mile Point Nuclear Station Unit No. 2 (NMP2), Oswego County, New York
Date of amendment request: June 29, 2009, as supplemented on August
13, 2009.
Description of amendment request: The proposed amendment would
revise the NMP2 Technical Specification (TS) 5.5.12 by replacing the
reference to Regulatory Guide (RG) 1.163 with a reference to Nuclear
Energy Institute (NEI) Topical Report NEI 94-01, Revision 2-A, as the
implementation document used by NMPNS to develop the NMP2 performance-
based leakage testing program in accordance with Option B of Title 10
of the Code of Federal Regulations (10 CFR) Part 50. The proposed
amendment would allow the next primary containment integrated leak rate
test (ILRT) to be performed within 15 years from the last ILRT as
opposed to the current 10-year interval, and would allow successive
ILRTs to be performed at 15-year intervals.
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 amendment involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed amendment involves changes to the NMP2 10 CFR 50
Appendix J Testing Program Plan. The proposed amendment does not
involve a physical change to the plant or a change in the manner in
which the plant is operated or controlled. The primary containment
function is to provide an essentially leak tight barrier against the
uncontrolled release of radioactivity to the environment for
postulated accidents. As such, the containment itself and the
testing requirements to periodically demonstrate the integrity of
the containment exist to ensure the plant's ability to mitigate the
consequences of an accident, and do not involve any accident
precursors or initiators. Therefore, the probability of occurrence
of an accident previously evaluated is not significantly increased
by the proposed amendment.
The proposed amendment adopts the NRC-accepted guidelines of NEI
94-01, Revision 2, for development of the NMP2 performance-based
leakage testing program. Implementation of these guidelines
continues to provide adequate assurance that during design basis
accidents, the primary containment and its components will limit
[[Page 53780]]
leakage rates to less [then] the values assumed in the plant safety
analyses. The potential consequences of extending the ILRT interval
from 10 years to 15 years have been evaluated by analyzing the
resulting changes in risk. The increase in risk in terms of person-
rem per year within 50 miles resulting from design basis accidents
was estimated to be acceptably small, and the increase in the large
early release frequency resulting from the proposed change was
determined to be within the guidelines published in NRC RG 1.174.
Additionally, the proposed change maintains defense-in-depth by
preserving a reasonable balance among prevention of core damage,
prevention of containment failure, and consequence mitigation. NMPNS
has determined that the increase in conditional containment failure
probability due to the proposed change would be very small.
Therefore, it is concluded that the proposed amendment does not
significantly increase the consequences of an accident previously
evaluated.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
The proposed amendment adopts the NRC-accepted guidelines of
NEI-94-01, Revision 2, for development of the NMP2 performance-based
leakage testing program, and establishes a 15 year interval for the
performance of the primary containment ILRT. The containment and the
testing requirements to periodically demonstrate the integrity of
the containment exist to ensure the plant's ability to mitigate the
consequences of an accident, and do not involve any accident
precursors and initiators. The proposed change does not involve a
physical change to the plant (i.e., no new or different type of
equipment will be installed) or a change to the manner in which the
plant is operated or controlled.
Therefore, the proposed amendment does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
Response: No.
The proposed amendment adopts the NRC-accepted guidelines of
NEI-94-01, Revision 2, for development of the NMP2 performance-based
leakage testing program, and establishes a 15 year interval for the
performance of the primary containment ILRT. The amendment does not
alter the manner in which safety limits, limiting safety system
setpoints, or limiting conditions for operation are determined. The
specific requirements and conditions of the 10 CFR 50 Appendix J
Testing Program Plan, as defined in the TS, ensure that the degree
of primary containment structural integrity and leak-tightness that
is considered in the plant safety analyses is maintained. The
overall containment leakage rate limit specified by the TS is
maintained, and the Type A, B, and C containment leakage tests will
continue to be performed at the frequencies established in
accordance with the NRC-accepted guidelines of NEI 94-01, Revision
2.
Containment inspections performed in accordance with other plant
programs serve to provide a high degree of assurance that the
containment will not degrade in a manner that is detectable only by
an ILRT. In addition, the on-line containment monitoring capability
that is inherent to inerted boiling water reactor containments
allows for the detection of gross containment leakage that may
develop during power operation. This combination of factors ensures
that evidence of containment structural degradation is identified in
a timely manner. Furthermore, a risk assessment using the current
NMP2 Probabilistic Risk Assessment model concluded that extending
the ILRT test interval from 10 years to 15 years results in a very
small change to the NMP2 risk profile.
Therefore, the proposed amendment 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.

Southern Nuclear Operating Company, Inc., Docket Nos. 50-348 and 50-
364, Joseph M. Farley Nuclear Plant, Units 1 and 2, Houston County,
Alabama
Date of amendment request: September 15, 2009.
Description of amendment request: The proposed amendment revises
Technical Specification (TS) 3.3.2, in Appendix A to Facility Operating
License Nos. NPF-2 and NPF-8 for the Joseph M. Farley Nuclear Plant
Units 1 and 2, respectively. P-11 is an engineered safety feature
actuation system (ESFAS) permissive/interlock which permits normal unit
cooldown and depressurization without actuation of safety injection
(SI) from low pressurizer pressure. P-12 is an ESFAS permissive/
interlock which permits normal unit cooldown and depressurization
without actuation of SI and main steam line isolation on the condition
of low steam line pressure. Both P-11 and P-12 circuits use input from
three protection channels. The current wording of Condition K in TS
3.3.2 states, ``Two channels inoperable.'' As a result, Condition K
does not explicitly address the possible conditions of one channel or
three channels inoperable, possibly creating a literal compliance
issue. The proposed Condition K change from ``Two channels inoperable''
to ``One or more channels inoperable'' will resolve the current literal
compliance issue. The change does not alter the current Condition K
required action, it simply clarifies that the required action must be
performed for one, two, or three P-11 or P-12 channels inoperable. In
addition, an editorial change is proposed for TS 5.6.8 to correct the
citation of a condition requiring a report for the post-accident
monitoring instrumentation. The current TS 5.6.8 text states, ``When a
report is required by Condition B or G of LCO [limiting conditions for
operation] 3.3.3. * * *'' The citation of Condition B is correct while
Condition G does not currently exist for LCO 3.3.3; instead TS 5.6.8
should cite Condition F.
Basis for proposed no significant hazards consideration
determination: As required by Title 10 of the Code of Federal
Regulations (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 amendment involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed change to TS 3.3.2 does not significantly increase
the probability or consequences of an accident previously evaluated
in the FSAR. These interlocks do not directly initiate an accident.
The consequences of accidents previously evaluated in the FSAR are
not adversely affected by these changes because the changes are made
to reflect the Improved Standard Technical Specifications and the
interlocks are verified to be in the required state for the unit
condition.
The proposed change to TS 5.6.8 corrects an editorial error and
therefore does not significantly increase the probability or
consequences of a previously evaluated accident.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
The proposed change to TS 3.3.2 does not create the possibility
of a new or different kind of accident than any accident already
evaluated in the FSAR. No new accident scenario, failure mechanisms,
or limiting single failures are introduced as a result of the
proposed change. The proposed TS 3.3.2 change does not challenge the
performance or integrity of any safety-related systems. Therefore,
this change does not create the possibility of a new or different
kind of accident from any accident previously analyzed.
The proposed change to TS 5.6.8 corrects an editorial error and
therefore does not create the possibility of a new or different kind
of accident from any accident previously analyzed.
[[Page 53781]]
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
Response: No.
The proposed change to TS 3.3.2 does not involve a significant
reduction in a margin of safety. The proposed change is made to
accurately reflect the format of the Improved Standard Technical
Specifications. The actuation setpoints specified by the Technical
Specifications and safety analysis limits assumed in the accident
analysis are unchanged. The margin of safety associated with these
trip setpoints and the safety analysis acceptance criteria is
unchanged. Therefore, the proposed change to TS 3.3.2 will not
significantly reduce the margin of safety as defined in the
Technical Specifications.
The proposed change to TS 5.6.8 corrects an editorial error and
therefore involves no significant reduction in a margin of safety.
Based on the above, SNC concludes that the proposed amendment
does not involve a significant hazards consideration under the
standards set forth in 10 CFR 50.92(c), and, accordingly, a finding
of ``no significant hazards consideration'' is justified.
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.

Tennessee Valley Authority (TVA), Docket Nos. 50-259, 50-260 and 50-
296, Browns Ferry Nuclear Plant, Units 1, 2 and 3, Limestone County,
Alabama
Date of amendment request: July 27, 2009 (TS-465).
Description of amendment request: The proposed change is to
eliminate Technical Specification (TS) surveillance requirement (SR)
3.6.1.3.11 and the requirement to perform water leak rate testing on
the listed containment isolation valves. More specifically, the
proposed change eliminates water local leak rate testing of valves in
the Containment Leak Rate Program that are being tested to verify the
combined leakage rate is within the limit that ensures the suppression
pool level is sufficient to keep lines that terminate below the water
level for at least 30 days without additional make-up.
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.
1. Does the proposed amendment involve a significant increase in
the probability or consequences of an accident previously evaluated?
This proposal does not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The proposed change to the scope of water leak rate testing for
the subject valves does not affect the probability of the design
basis accidents. The valves will continue to be maintained in an
operable state, and in their current design configuration. There is
no correlation between the scope of the water leak rate testing and
accident probability.
TVA reviewed the postulated consequences of design basis events
on primary containment isolation under the proposed change. The
primary containment structure, including access openings,
penetrations and the containment heat removal system, is designed so
that the containment structure and its internal compartments can
withstand, without exceeding the design leakage rate (2.0% per day),
the peak accident pressure and temperature that could occur during
any postulated LOCA [loss-of-coolant accident].
For the purposes of considering the consequences of LOCAs under
the proposed change, a single active failure of a CIV [containment
isolation valve] or a passive failure of the closed system were
reviewed, within the limits of the existing licensing basis. Under
the existing licensing basis, a pipe rupture of seismically
qualified ECCS [emergency core cooling system] piping does not have
to be assumed concurrent with the LOCA, except if it is a
consequence of the LOCA. Consequential failures can be eliminated,
since a LOCA inside containment is separated from the ECCS piping by
the containment structure. Consequential failures of the ECCS piping
from LOCA's outside containment are outside the Appendix J design
considerations, although they are adequately addressed through the
redundancy and separation of the ECCS design. A single active
failure of the CIV, under the LOCA condition, can be accommodated
since the closed and filled system piping and the suppression pool
water inventory remain as the leakage barriers. The ECCS passive
failure criterion does require consideration of system leaks, but
not pipe breaks, beyond the initiating LOCA. Pipe leakage,
equivalent to the leakage from a valve or pump seal failure, should
be considered at 24 hours or greater post-LOCA. The capability to
make-up inventory to the suppression pool is adequate to ensure that
postulated seat leakage and pipe leakage does not result in a
condition that jeopardizes pool level. Make-up capability exists to
the suppression pool. Actions to make-up to the suppression pool are
delineated in Emergency Operating Instructions.
Therefore, the proposal to eliminate the subject water leak rate
tests does not involve a significant increase in the probability or
consequences of an accident previously evaluated.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
This proposal does not create the possibility of a new or
different kind of accident from any accident previously evaluated.
The acceptability of the proposed change to the scope of water
leak rate testing for the subject valves is based on maintaining the
existing barriers to primary containment leakage, and ensuring that
the suppression pool level is assured for 30 days during all design
basis, post-accident modes of operation. By meeting these dual
objectives, the plant response to the design basis events will be
unchanged, and no new accident scenarios will be encountered. These
two objectives are related, in that, the suppression pool inventory
creates a passive barrier to primary containment atmospheric leakage
for valves associated with penetrations which are located below the
minimum water level of the pool.
The proposed Technical Specification change does not alter the
configuration of the subject containment isolation valves or their
associated systems. The valves will continue to be tested and
maintained to ensure their operability. The subject valves are all
isolation valves associated with lines that penetrate the primary
containment. For closed system valves, the redundant isolation
boundary for each of the affected valves is the closed system
associated with the valve. The closed system piping is verified via
a 10 CFR 50 Appendix J Type A test. The integrity of the closed
systems is also monitored and controlled via Technical Specification
5.5.2, ``Primary Coolant Sources Outside Containment.''
The subject valves may be open, or change state, post-accident
to support the design function of their associated ECCS systems
(HPCI [high-pressure coolant injection], Core Spray, RHR [residual
heat removal]), RCIC [reactor core isolation coolant] or RHR
Sampling using the Post Accident Sampling System. The subject valves
function as system valves during the periods when they are open or
in an intermediate state, not as containment isolation valves.
Reliance is placed on the suppression pool seal and the closed
system piping to maintain the barrier between primary and secondary
containment atmospheres.
Therefore, with the valve configuration and closed systems
configuration unaffected by the proposed change, the existing
barriers to primary containment atmospheric leakage are maintained,
so long as the suppression pool level is ensured.
The suppression pool is designed and operated so that it is
filled with water in accordance with Technical Specifications
3.6.2.2, ``Suppression Pool Water Level,'' and the associated Bases.
As such, the supply of water in the suppression pool is assured for
30 days during all design basis, post-accident modes of operation.
Water leak rate testing has historically been performed on valves
associated with lines that connect to the suppression pool. The
acceptance criteria for combined leakage from these penetrations is
72.79 cfh [cubic feet per hour]. This leakage rate is at a level
which ensures the 30-day post-accident suppression pool level.
[[Page 53782]]
As mentioned above, the integrity of the closed system piping is
verified via a 10 CFR 50 Appendix J Type A test and is monitored and
controlled via Technical Specification 5.5.2. TS 5.5.2 establishes a
program to monitor and control leakage from systems located outside
containment that could contain highly radioactive fluids during a
serious transient or accident. This program applies to the ECCS and
RCIC systems affected by the proposed change and ensures that
leakage into secondary containment via packing, flanges, seals,
etc., is controlled. Leakage from these systems has been found to be
very low, and well below the 20 gpm [gallons per minute] limit
established for these systems. The proposed change is not expected
to contribute to higher levels of system leakage. Normal operational
monitoring of suppression pool level, operator rounds, housekeeping
inspections, and system pressure testing further ensure external
leakage is identified and minimized while suppression pool level is
being maintained.
A review of water leak rate test data for the subject CIVs
showed that the valves have had leakage rates within the acceptance
criteria. Testing of the valves in accordance with ASME [American
Society of Mechanical Engineers] Code requirements ensure valve
operability.
Therefore, leakage past the CIVs is expected to be low and in
keeping with the design basis for the suppression pool. However, the
capability does exist to make-up water to the suppression pool if
necessary. Existing Emergency Operating Instructions require actions
if suppression pool level is less than the required level. Thus, the
level of the suppression pool is ensured, independent of the current
CIV water leak rate testing requirement.
The proposed change to the scope of water leak rate testing for
the subject valves maintains the existing barriers to primary
containment leakage, and ensures that the suppression pool level is
assured for 30 days during all design basis, post-accident modes of
operation. Therefore, the plant response to the design basis events
is unchanged, and the proposal does not create the possibility of a
new or different kind of accident from any accident previously
evaluated.
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
This change does not involve a significant reduction in a margin
of safety.
As discussed in the responses to questions 1 and 2, the proposed
change does not alter the plant response to existing accident
scenarios, and does not introduce new or different scenarios. So the
margin of safety from a design basis accident standpoint is
maintained.
Historically, the leakage rate through the subject valves has
been determined in accordance with TS SR 3.6.1.3.11. This leakage
rate has always been within the acceptance criteria. Quantifying
leakage past the CIVs has been used to ensure that the suppression
pool level is assured for 30 days post-accident. Under the proposed
change, this leakage rate will not be quantified. In addition,
closed system leakage is monitored and controlled by an existing
Technical Specification program. Closed system leakage has been
found to be very low on each of the units, and is currently well
below the 20 gpm allowable. Therefore, leakage past the CIVs is
expected to be low and in keeping with the design basis for the
suppression pool. However, the capability does exist, and is
proceduralized, to make-up water to the suppression pool if
necessary. Thus the current capability to maintain adequate
suppression pool level for 30 days post-accident is assured under
the proposed change.
Therefore the proposed change to the scope of water leak rate
testing for the subject valves does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
