NUCLEAR REGULATORY COMMISSION
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 staff) 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 February 28, 2008 to March 12, 2008. The
last biweekly notice was published on March 11, 2008 (73 FR 13021).
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 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,
Directives and Editing 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 Commission's
Public Document Room (PDR), located at One White Flint North, Public
File Area O1F21, 11555 Rockville Pike (first floor), Rockville,
Maryland. The filing of requests for a hearing and petitions for leave
to intervene is discussed below.
Within 60 days after the date of publication of this notice,
person(s) 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
via electronic submission through the NRC E-Filing system 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 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 01F21, 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 within 60
days, 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 set forth 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
[[Page 15781]]
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.
If a hearing is requested, and the Commission has not made a final
determination on the issue of no significant hazards consideration, 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 hearing or a petition for leave to intervene 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 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 a waiver in accordance with the procedures described below.
To comply with the procedural requirements of E-Filing, at least
five (5) days prior to the filing deadline, the petitioner/requestor
must 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 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 technical help line,
which is available between 8:30 a.m. and 4:15 p.m., Eastern Time,
Monday through Friday. The help line number is (800) 397-4209 or
locally, (301) 415-4737.
Participants who believe that they have a good cause for not
submitting documents electronically must file a motion, 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 petition
and/or request 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). To be timely, filings must be submitted no later
than 11:59 p.m. Eastern Time on the due date.
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. 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 submission.

Duke Power Company LLC, 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 11, 2007.
Description of amendment request: The amendments would revise the
[[Page 15782]]
Technical Specifications (TSs) permitting relaxation of the allowed
bypass test times and completion times for various systems in
accordance with Technical Specification Task Force Traveler (TSTF) 418,
Revision 2, ``RPS and ESFAS Test Times and Completion Times (WCAP-
14333).
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:
First Standard
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?
Response: No.
The proposed changes to the Completion Times, bypass test time,
and Surveillance Frequencies reduces the potential for inadvertent
reactor trips and spurious actuations, and therefore do not increase
the probability of any accident previously evaluated. The proposed
changes to the Completion Times and bypass test time do not change
the response of the plant to any accidents and have an insignificant
impact on the reliability of the reactor trip system and engineered
safety feature actuation system (RTS and ESFAS) signals. The RTS and
ESFAS will remain highly reliable and the proposed changes will not
result in a significant increase in the risk of plant operation.
This is demonstrated by showing that the impact on plant safety as
measured by core damage frequency (CDF) is less than 1.0E-06 per
year and the impact on large early release frequency (LERF) is less
than 1.0E-07 per year. In addition, for the Completion Time change,
the incremental conditional core damage probabilities (ICCDP) and
incremental conditional large early release probabilities (ICLERP)
are less than 5.0E-07 and 5.0E-08, respectively. These changes meet
the acceptance criteria in Regulatory Guides 1.174 and 1.177.
Therefore, since the RTS and ESFAS will continue to perform their
functions with high reliability as originally assumed, and the
increase in risk as measured by CDF, LERF, ICCDP, and ICLERP is
within the acceptance criteria of existing regulatory guidance,
there will not be a significant increase in the consequences of any
accidents.
The proposed changes do not adversely affect accident initiators
or precursors nor alter the design assumptions, conditions, or
configuration of the facility or the manner in which the plant is
operated and maintained. The proposed changes do not alter or
prevent the ability of structures, systems, and components (SSCs)
from performing their intended function to mitigate the consequences
of an initiating event within the assumed acceptance limits. The
proposed changes do not affect the source term, containment
isolation, or radiological release assumptions used in evaluating
the radiological consequences of an accident previously evaluated.
Further, the proposed changes do not increase the types or amounts
of radioactive effluent that may be released offsite, nor
significantly increase individual or cumulative occupational/public
radiation exposures. The proposed changes are consistent with safety
analysis assumptions and resultant consequences.
The determination on risk impacts that the results of the
proposed changes are acceptable was established in the NRC Safety
Evaluations prepared for WCAP-14333-P-A (issued by letter dated July
15, 1998) and for WCAP-15376-P-A (issued by letter dated December
20, 2002). Implementation of the proposed changes will result in an
insignificant risk impact. Applicability of these conclusions has
been verified through plant-specific reviews and implementation of
the generic analysis results in accordance with the respective NRC
Safety Evaluation conditions.
The proposed changes based on TSTF-246 do not involve any
physical alteration of plant SSCs. The remaining intermediate range
and power range nuclear instruments remain operable and have
required actions that ensure compliance with applicable safety
analyses.
Therefore, it is concluded that this change does not increase
the probability of occurrence of a malfunction of equipment
important to safety.
Second Standard
Does operation of the facility in accordance with the proposed
amendment create the possibility of a new or different kind of
accident from any accident previously evaluated?
Response: No.
The proposed changes do not result in a change in the manner in
which the RTS or ESFAS provide plant protection. The RTS and ESFAS
will continue to have the same setpoints after the proposed changes
are implemented. There are no design changes associated with the
license amendment. The changes to Completion Times, bypass test
times, and Surveillance Frequencies do not change any existing
accident scenarios, nor create any new or different accident
scenarios. The changes do not involve a physical alteration of the
plant (i.e., no new or different type of equipment will be
installed) or a change in the methods governing normal plant
operation. In addition, the changes do not alter assumptions made in
the safety analysis. The proposed changes are consistent with the
safety analysis assumptions and current plant operating practice.
The proposed changes do not introduce new failure mechanisms for
systems, structures, or components not already considered in the
UFSAR. Therefore, the possibility of a new or different kind of
accident from any accident previously evaluated is not created
because no new failure mechanisms or initiating events have been
introduced.
Third Standard
Does operation of the facility in accordance with the proposed
amendment involve a significant reduction in the margin of safety?
Response: No.
The proposed changes do not alter the manner in which safety
limits, limiting safety system settings, or limiting conditions for
operation are determined. The safety analysis acceptance criteria
are not impacted by these changes.
Redundant RTS and ESFAS trains are maintained, and diversity
with regard to the signals that provide reactor trip and ESFAS is
also maintained. Signals credited as primary or secondary and
operator actions credited in the accident analyses will remain the
same. The proposed changes will not result in plant operation in a
configuration outside design basis. The calculated impact on risk is
insignificant and meets the acceptance criteria contained in
Regulatory Guides 1.174 and 1.177. Although there was no attempt to
quantify any positive human factors benefit due to increased
Completion Times and bypass test time, it is expected that there
would be a net benefit due to a reduced potential for spurious
reactor trips and actuations associated with testing.
Implementation of the proposed changes is expected to result in
an overall improvement in safety, as follows:
a. Reduced testing will result in fewer inadvertent reactor
trips, less frequent actuation of ESFAS components, less frequent
distraction of operations personnel without significantly affecting
RTS and ESFAS reliability.
b. Improvements in the effectiveness of the operating staff in
monitoring and controlling plant operation will be realized. This is
due to less frequent distraction of the operators and shift
supervisor to attend to instrumentation Required Actions with short
Completion Times.
c. Longer repair times associated with increased Completion
Times will lead to higher quality repairs and improved reliability.
d. The Completion Time extensions for the reactor trip breakers
will provide the utilities additional time to complete test and
maintenance activities while at power, potentially reducing the
number of forced outages related to compliance with reactor trip
breaker Completion Times, and provide consistency with the
Completion Times for the logic trains.
Therefore, it is concluded that this 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.

Duke Power Company LLC, Docket Nos. 50-369 and 50-370, McGuire Nuclear
Station, Units 1 and 2, Mecklenburg County, North Carolina
Date of amendment request: January 22, 2008.
Description of amendment request: The proposed amendments would
modify Technical Specification (TS) requirements related to control
room envelope habitability in accordance with Technical Specification
Task Force (TSTF)-448, Revision 3, ``Control Room Habitability.'' For
McGuire Nuclear Station, Units 1 and 2, this TSTF revises TS 3.7.9,
Control Room Area Ventilation System (CRAVS), and adds a new
administrative controls program, TS 5.5.16, Control Room Envelope
Habitability Program.
The NRC staff issued a notice of opportunity for comment in the
Federal Register on October 17, 2006 (71 FR 61075) on possible license
amendments adopting TSTF-448 using the NRC's consolidated line item
improvement process (CLIIP) for amending the licensee's TSs, which
included a model safety evaluation (SE) and model no significant
hazards consideration (NSHC) determination. The NRC staff subsequently
issued a notice of availability of the models for referencing in
license amendment applications in the Federal Register on January 17,
2007 (72 FR 2022), which included the resolution of public comments on
the model SE. The licensee has affirmed the applicability of the
following NSHC determination in its application.
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 does not adversely affect accident
initiators or precursors nor alter the design assumptions,
conditions, or configuration of the facility. The proposed change
does not alter or prevent the ability of structures, systems, and
components (SSCs) to perform their intended function to mitigate the
consequences of an initiating event within the assumed acceptance
limits. The proposed change revises the TS for the control room
envelope (CRE) emergency ventilation system, which is a mitigation
system designed to minimize unfiltered air leakage into the CRE and
to filter the CRE atmosphere to protect the CRE occupants in the
event of accidents previously analyzed. An important part of the CRE
emergency ventilation system is the CRE boundary. The CRE emergency
ventilation system is not an initiator or precursor to any accident
previously evaluated. Therefore, the probability of any accident
previously evaluated is not increased. Performing tests to verify
the operability of the CRE boundary and implementing a program to
assess and maintain CRE habitability ensure that the CRE emergency
ventilation system is capable of adequately mitigating radiological
consequences to CRE occupants during accident conditions, and that
the CRE emergency ventilation system will perform as assumed in the
consequence analyses of design basis accidents. Thus, the
consequences of any accident previously evaluated are not increased.
Therefore, the proposed 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 Accident Previously
Evaluated
The proposed change does not impact the accident analysis. The
proposed change does not alter the required mitigation capability of
the CRE emergency ventilation system, or its functioning during
accident conditions as assumed in the licensing basis analyses of
design basis accident radiological consequences to CRE occupants. No
new or different accidents result from performing the new
surveillance or following the new program. The proposed change does
not involve a physical alteration of the plant (i.e., no new or
different type of equipment will be installed) or a significant
change in the methods governing normal plant operation. The proposed
change does not alter any safety analysis assumptions and is
consistent with current plant operating practice. Therefore, 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 proposed change does not alter the manner in which safety
limits, limiting safety system settings or limiting conditions for
operation are determined. The proposed change does not affect safety
analysis acceptance criteria. The proposed change will not result in
plant operation in a configuration outside the design basis for an
unacceptable period of time without compensatory measures. The
proposed change does not adversely affect systems that respond to
safely shut down the plant and to maintain the plant in a safe
shutdown condition.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff proposes to determine that the amendment request
involves no significant hazards consideration.

Entergy Nuclear Operations, Inc., Docket No. 50-247, Indian Point
Nuclear Generating Unit No. 2 (IP2), Westchester County, New York
Date of amendment request: December 13, 2007.
Description of amendment request: The proposed amendment would add
some Emergency Core Cooling System (ECCS) valves and remove other ECCS
valves from Surveillance Requirement (SR) 3.5.2.1. The purpose of the
SR is to verify that ECCS valves whose single failure could cause loss
of the ECCS function are in the required position with power removed so
that the single failure could not occur. The valves being added are
currently controlled administratively. The valves being removed have
been evaluated to demonstrate that a single failure would not cause
loss of the ECCS function.
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 adds three ECCS valves and removes four ECCS
valves from IP2 SR 3.5.2.1. The purpose of the surveillance is to
assure that the valves are in their required position with power
removed so that misalignment or single failure cannot prevent
completion of the ECCS function. The performance of the SR does not
involve any actions related to the initiation of an accident and
therefore the proposed changes cannot increase the probability of an
accident. Misalignment or single failure of one of the three valves
being added to TS could cause a loss of the ECCS function so the
change will not increase the consequences of an accident but rather
provide assurance that no such increase can occur. Removal of the
four valves has been evaluated and the evaluation demonstrates that
the misalignment or single failure of one of the valves will not
affect the ECCS function and therefore will not increase the
consequences of an accident. 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?
[[Page 15785]]
Response: No.
The proposed change adds three ECCS valves and removes four ECCS
valves from IP2 SR 3.5.2.1. The purpose of the surveillance is to
assure that the valves are in their required position with power
removed so that misalignment or single failure cannot prevent
completion of the ECCS function. The removal of valves from the
surveillance allows power to be maintained to the valves during
normal operation but does not otherwise affect the function of the
valves or the design and operation of plant systems. The addition of
power does mean that the valves could fail open but this does not
create the possibility of a new or different type of accident since
such a failure mode is currently evaluated. The performance of the
SR for added valves does not affect the function of the valves or
the manner in which the valves or their systems are operated or any
procedures used for valve or system operation. The change assures
that the valves will be in their correct position and does not
introduce any new failure modes or the possibility of a different
accident. Therefore, the proposed 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
the margin of safety?
Response: No.
The proposed change adds three ECCS valves and removes four ECCS
valves from IP2 SR 3.5.2.1. The purpose of the surveillance is to
assure that the valves are in their required position with power
removed so that misalignment or single failure cannot prevent
completion of the ECCS function. The addition of the three valves to
the TS provides additional assurance that operation will be with
power removed and the valves in the correct position. This increases
safety margin. Removal of valves from the surveillance is based on
analysis of the effects of misalignment or single failure on the
ECCS function. Analysis demonstrates that the misalignment or single
failure would not adversely affect the ECCS function and therefore
there is no significant reduction in the margin of safety. The
margin of safety remains adequate to assure the ECCS function is
performed.
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.

Point Nuclear Generating Unit Nos. 2 and 3, Westchester County, New

Date of amendment request: December 18, 2007.
Description of amendment request: The proposed amendment would
modify Technical Specification (TS) requirements related to control
room envelope habitability by adding a Control Room Envelope
Habitability Program and then referencing this program in place of
existing surveillances. It also standardizes terminology and modifies
other TS related to the control room envelope.
This change was proposed by the industry's Technical Specification
Task Force (TSTF) and is designated TSTF-448, Revision 3. The NRC staff
issued a notice of opportunity for comment in the Federal Register on
October 17, 2006 (71 FR 61075), on possible amendments concerning TSTF-
448, including a model safety evaluation and model no significant
hazards (NSHC) determination, using the consolidated line item
improvement process (CLIIP). The NRC staff subsequently issued a notice
of availability of the models for referencing in license amendment
applications in the Federal Register on January 17, 2007 (72 FR 2022).
The licensee affirmed the applicability of the following NSHC
determination in its application dated December 18, 2007.
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 does not adversely affect accident
initiators or precursors nor alter the design assumptions,
conditions, or configuration of the facility. The proposed change
does not alter or prevent the ability of structures, systems, and
components (SSCs) to perform their intended function to mitigate the
consequences of an initiating event within the assumed acceptance
limits.
The proposed change revises the TS for the CRE emergency
ventilation system, which is a mitigation system designed to
minimize unfiltered air leakage into the CRE and to filter the CRE
atmosphere to protect the CRE occupants in the event of accidents
previously analyzed. An important part of the CRE emergency
ventilation system is the CRE boundary. The CRE emergency
ventilation system is not an initiator or precursor to any accident
previously evaluated. Therefore, the probability of any accident
previously evaluated is not increased.
Performing tests to verify the operability of the CRE boundary
and implementing a program to assess and maintain CRE habitability
ensure that the CRE emergency ventilation system is capable of
adequately mitigating radiological consequences to CRE occupants
during accident conditions, and that the CRE emergency ventilation
system will perform as assumed in the consequence analyses of design
basis accidents. Thus, the consequences of any accident previously
evaluated are not increased.
Therefore, the proposed 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 Accident Previously
Evaluated
The proposed change does not impact the accident analysis. The
proposed change does not alter the required mitigation capability of
the CRE emergency ventilation system, or its functioning during
accident conditions as assumed in the licensing basis analyses of
design basis accident radiological consequences to CRE occupants. No
new or different accidents result from performing the new
surveillance or following the new program. The proposed change does
not involve a physical alteration of the plant (i.e., no new or
different type of equipment will be installed) or a significant
change in the methods governing normal plant operation. The proposed
change does not alter any safety analysis assumptions and is
consistent with current plant operating practice.
Therefore, 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

The proposed change does not alter the manner in which safety
limits, limiting safety system settings or limiting conditions for
operation are determined. The proposed change does not affect safety
analysis acceptance criteria. The proposed change will not result in
plant operation in a configuration outside the design basis for an

Point Nuclear Generating Unit Nos. 2 and 3, Westchester County, New
York
Date of amendment request: December 20, 2007.
Description of amendment request: The proposed amendment would
modify Technical Specifications (TS), to replace the current limits on
primary coolant gross specific activity with limits on primary coolant
noble gas activity. The noble gas activity would be based on DOSE
EQUIVALENT XE-133 and would take into account only the noble gas
activity in the primary coolant.
This change was proposed by the industry's Technical Specification
Task Force (TSTF) and is designated TSTF-490. The NRC staff issued a
notice of opportunity for comment in the Federal Register on November
20, 2006 (71 FR 67170), on possible amendments concerning TSTF-490,
including a model safety evaluation and model no significant hazards
(NSHC) determination, using the consolidated line item improvement
process (CLIIP). The NRC staff subsequently issued a notice of
availability of the models for referencing in license amendment
applications in the Federal Register on March 15, 2007 (72 FR 12217).
The licensee affirmed the applicability of the following NSHC
determination in its application dated December 20, 2007.
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
Reactor coolant specific activity is not an initiator for any
accident previously evaluated. The Completion Time when primary
coolant gross activity is not within limit is not an initiator for
any accident previously evaluated. The current variable limit on
primary coolant iodine concentration is not an initiator to any
accident previously evaluated. As a result, the proposed change does
not significantly increase the probability of an accident. The
proposed change will limit primary coolant noble gases to
concentrations consistent with the accident analyses. The proposed
change to the Completion Time has no impact on the consequences of
any design basis accident since the consequences of an accident
during the extended Completion Time are the same as the consequences
of an accident during the Completion Time. As a result, the
consequences of any accident previously evaluated are not
significantly increased.
Criterion 2--The Proposed Change Does Not Create the Possibility of a
New or Different Kind of Accident From Any Accident Previously
Evaluated
The proposed change in specific activity limits does not alter
any physical part of the plant nor does it affect any plant
operating parameter. The change does not create the potential for a
new or different kind of accident from any previously evaluated.
Criterion 3--The Proposed Change Does Not Involve a Significant
Reduction in the Margin of Safety
The proposed change revises the limits on noble gas
radioactivity in the primary coolant. The proposed change is
consistent with the assumptions in the safety analyses and will
ensure the monitored values protect the initial assumptions in the
safety analyses.
The NRC staff has reviewed this 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 Plant,
Van Buren County, Michigan
Date of amendment request: January 31, 2008.
Description of amendment request: The proposed amendment would
revise the Technical Specifications (TS) to change the description of
fuel assemblies specified in TS 4.2.1, and add the Framatome Advanced
Nuclear Power, Inc. (ANP) report, BAW-10240(P)-A, ``Incorporation of M5
Properties in Framatome ANP Approved Methods,'' to the analytical
methods referenced in TS 5.6.5.b to permit the use of M5 alloy for fuel
rod cladding and fuel assembly structural components in future
operating cycles.
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 license amendment adds a Nuclear Regulatory
Commission approved analytical method, BAW-10240(P)-A,
``Incorporation of M5 Properties in Framatome ANP Approved
Methods,'' used to determine the core operating limits, to Technical
Specification (TS) 5.6.5.b and changes the description of fuel
assemblies specified in TS 4.2.1 to allow use of the M5 alloy. The
proposed amendment does not affect the acceptance criteria for any
Final Safety Analysis Report (FSAR) safety analysis analyzed
accidents and anticipated operational occurrences. 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. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
Use of M5 clad fuel will not result in changes in the operation
or configuration of the facility. Topical report BAW-10240(P)-A
describes, by reference, that the material properties of the M5
alloy are similar or better than those of zircaloy-4. Therefore, M5
fuel rod cladding and fuel assembly structural components will
perform similarly to those fabricated from zircaloy-4, thus
precluding the possibility of the fuel becoming an accident
initiator and causing a new or different type of accident.
Since the material properties of M5 alloy are similar or better
than those of zircaloy-4, there will be no significant changes in
the types of any effluents that may be released off-site. There will
not be a significant increase in occupational or public radiation
exposure.
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 the changes being requested.
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 change will not involve a significant reduction in
the margin of safety because it has been demonstrated that the
material properties of the M5 alloy are not significantly different
from those of zircaloy-4. M5 alloy is expected to perform similarly
or better than zircaloy-4 for all normal operating and accident
scenarios, including both loss-of-coolant accident (LOCA) and non-
LOCA scenarios. The proposed changes do not affect the acceptance
criteria for any FSAR safety analysis analyzed accidents or
anticipated operational occurrences. All required safety limits
would 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.

Description of amendment request: The proposed amendments would
revise Technical Specification (TS) 5.5.16.a, ``Containment Leakage
Rate Testing Program,'' to add an exception to Regulatory Guide 1.163
to allow the use of Standard ANSI/ANS 56.8-2002, and to revise TS
5.5.16.b to specify both a lower peak calculated containment internal
pressure following a large-break loss-of-coolant accident (LOCA) and
containment design pressure.
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. [Do] the proposed change[s] involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed change to TS 5.5.16.a adds an exception to
Regulatory Guide 1.163 to specify use of Standard ANSI/ANS-56.8-
2002, rather than ANSI/ANS-56.8-1994.
The proposed change to TS 5.5.16.b specifies both the peak
calculated containment internal pressure with margin following a
large-break LOCA and the containment design pressure.
These changes only affect the applicable version of the standard
(2002 in place of 1994) and the test pressures for containment leak-
rate tests, and do not involve the modification of any plant
equipment or have any effect on plant operation. The changes are
made based on the safety analysis and containment design, and do not
have any adverse effect on accidents previously evaluated.
Therefore, the proposed changes do not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. [Do] the proposed change[s] create the possibility of a new
or different accident from any accident previously evaluated?
Response: No.
The proposed changes do not involve a physical alteration to the

The changes are made based on the safety analysis and containment
design, and do not affect any previously evaluated accidents.
Therefore, the proposed change[s] [do] not create the
possibility of a new or different accident from any accident
previously evaluated.
3. [Do] the proposed change[s] involve a significant reduction
in a margin of safety?
Response: No.
The proposed changes do not alter the manner in which safety
limits, limiting safety system settings, or limiting conditions for
operation are determined. The safety analysis acceptance criteria
are not affected by these changes, and the changes will not result
in plant operation in a configuration outside the design basis.
Therefore, the proposed changes do not involve a significant
reduction in a margin of safety.

Date of amendment request: January 28, 2008.
Description of amendment request: The amendments would revise the
Technical Specifications (TS) to establish an Action in TS 3.3.1,
``Reactor Trip Instrumentation,'' for two inoperable channels of
extended range neutron flux instrumentation. The licensee also proposes
a minor correction to revise ACTION c of TS 3.4.1.4.2, ``Reactor
Coolant System, Cold Shutdown--Loops Not Filled,'' to change the
requirement for verification of boron concentration to verification of
shutdown margin.
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. [Do] the proposed change[s] involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The extended range neutron flux monitoring instrumentation that
is the subject of the proposed change performs a monitoring function
and of itself has no potential as an accident initiator. The
proposed requirement for the condition where both channels of the
function are inoperable establishes actions that preserve the design
basis where no actions previously existed. This is a more
restrictive change and thus does not increase the probability or
consequences of an accident previously evaluated.
The proposed change[s] to TS 3.4.1.4.2 ACTION c. clarification
regarding the verification of shutdown margin [do] not result in any
technical change in the way the TS ACTION is applied. Therefore this
proposed change does not increase the probability or consequences of
an accident previously evaluated.
The proposed change[s] [include] formatting changes that are
administrative and consequently have no effect on accident analyses.
Therefore, the proposed change[s] [do] not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. [Do] the proposed change[s] create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
The proposed changes do not involve any physical alteration of
plant equipment and [do] not change the method by which any safety
related structure, system, or component performs its function or is
tested. As such, no new or different types of equipment will be
installed, and the basic operation of installed equipment is
unchanged. The methods governing plant operation and testing remain
consistent with current safety analysis assumptions.
The proposed change[s] [include] formatting changes that are
administrative and consequently have no effect on accident analyses.
Therefore, the proposed change[s] will not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. [Do] the proposed change[s] involve a significant reduction
in a margin of safety?
Response: No.
The proposed changes do not negate any existing requirement, and
d[o] not adversely affect existing plant safety margins or the
reliability of the equipment assumed to operate in the safety
analysis. The purpose of the proposed changes is to provide greater
assurance that the design basis is maintained. There are no changes
being made to safety analysis assumptions, safety limits or safety
system settings that would adversely affect plant safety as a result
of the proposed change[s].
The proposed change[s] [include] formatting changes that are

1. [Do] the proposed change[s] involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed Technical Specification changes to revise the
action requirements associated with the containment air lock will
not cause an accident to occur and will not result in any change in
the operation of the associated accident mitigation equipment. The
containment air lock is not an accident initiator. The proposed
changes will not revise the operability requirements (e.g., leakage
limits) for the containment air lock. Proper operation of the
containment air lock will still be verified. As a result, the design
basis accidents will remain the same postulated events described in
the South Texas Project Unit 1 and Unit 2 Updated Final Safety
Analysis Report, and the consequences of the design basis accidents
will remain the same.
Therefore, the proposed changes will not increase the
probability or consequences of an accident previously evaluated.
2. [Do] the proposed change[s] create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
The proposed changes to the Technical Specifications do not
impact any system or component that could cause an accident. The
proposed changes will not alter the plant configuration (no new or
different type of
[[Page 15789]]
equipment will be installed) or require any unusual operator
actions. The proposed changes will not alter the way any structure,
system, or component functions, and will not significantly alter the
manner in which the plant is operated. The response of the plant and
the operators following an accident will not be different. In
addition, the proposed changes do not introduce any new failure
modes.
Therefore, the proposed changes will not create the possibility
of a new or different kind of accident from any accident previously
analyzed.
3. [Do] the proposed change[s] involve a significant reduction
in a margin of safety?
Response: No.
The proposed Technical Specification changes to revise the
action requirements associated with the containment air lock will
not cause an accident to occur and will not result in any change in
the operation of the associated accident mitigation equipment. The
operability requirements for the containment air lock have not been
changed. The containment air lock will continue to function as
assumed in the safety analysis. In addition, the proposed changes
will not adversely affect equipment design or operation, and there
are no changes being made to the Technical Specification required
safety limits or safety system settings that would adversely affect
plant safety.
Therefore, the proposed changes will not result in 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 standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
request for amendments involves no significant hazards consideration.

Union Electric Company, Docket No. 50-483, Callaway Plant, Unit 1,
Callaway County, Missouri
Date of amendment request: December 28, 2007.
Description of amendment request: The proposed amendment would
revise Technical Specification Administrative Controls Section 5.5.8,
``Inservice Testing Program,'' to indicate that the Inservice Testing
Program shall include testing frequencies applicable to the American
Society of Mechanical Engineers (ASME) Code for Operation and
Maintenance, and to indicate that there may be some non-standard
frequencies specified as 2 years or less in the Inservice Testing
Program to which the provisions of Surveillance Requirement 3.0.2 is
applicable.
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 change revises TS 5.5.8, ``Inservice Testing
Program,'' for consistency with the requirements of 10 CFR
50.55a(f)(4) regarding the inservice testing of pumps and valves.
The proposed change incorporates revisions to the ASME Code that
result in a net improvement in the measures for testing pumps and
valves. The proposed change does not impact any accident initiators
or analyzed events or assumed mitigation of accident or transient
events, nor does it involve the addition or removal of any
equipment, or any design changes to the facility. Therefore, the
proposed change does not represent 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 change revises TS 5.5.8, ``lnservice Testing
Program,'' for consistency with the requirements of 10 CFR
50.55a(f)(4) regarding the inservice testing of pumps and valves.
The proposed change incorporates revisions to the ASME Code that
result in a net improvement in the measures for testing pumps and
valves.
The proposed change does not involve a modification to the
physical configuration of the plant (i.e., no new equipment will be
installed) or change in the methods governing normal plant
operation. The proposed change will not impose any new or different
requirements or introduce a new accident initiator, accident
precursor, or malfunction mechanism. Additionally, there is no
change in the types or increases in the amounts of any effluent that
may be released off-site, and there is no increase in individual or
cumulative occupational exposure. Therefore, this proposed change
does not create the possibility of an accident of a different kind
than previously evaluated.
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
Response: No
The proposed change revises TS 5.5.8, ``Inservice Testing
Program, '' for consistency with the requirements of 10 CFR
50.55a(f)(4) regarding the inservice testing of pumps and valves.
The proposed change incorporates revisions to the ASME Code that
result in a net improvement in the measures for testing pumps and
valves. The safety functions of the affected pumps and valves will
be maintained. Therefore, this 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.

Union Electric Company, Docket No. 50-483, Callaway Plant, Unit 1,
Callaway County, Missouri
Date of amendment request: December 28, 2007.
Description of amendment request: The amendment would revise
Technical Specifications (TS) 3.7.2, to add the Main steam isolation
valve (MSIV) bypass valves to the scope of the TS. The proposed changes
include a revision to the APPLICABILITY for the TS and a revision to
footnote (i) in Table 3.3.2-1 of TS 3.3.2, ``ESFAS Instrumentation,''
to make it consistent with the revised Applicability of LCO 3.7.2. The
amendment would also add new TS 3.7.19, ``Secondary System Isolation
Valves (SSIVs),'' to include Limiting Conditions for Operation and
Surveillance Requirements for the secondary system isolation valves:
Main steam low point drain isolation valves, steam generator chemical
injection isolation valves, steam generator blowdown isolation valves,
and steam generator sample line isolation valves.
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 change adds requirements to the TS to ensure that
systems and components are maintained consistent with the safety
analysis and licensing basis.
Requirements are incorporated into the TS for secondary system
isolation valves. These changes do not involve any design or
physical changes to the facility, including the SSIVs themselves.
The design and functional performance requirements, operational
characteristics, and reliability of the SSIVs are unchanged. There
is no impact on the design safety function of MSIVs, MFIVs, MFRVs or
MFRVBVs [main steam isolation valves, main feedwater isolation
valves, main feedwater regulating valves, main isolation feedwater
regulating valve bypass valves] to close (either as an accident
mitigator or as a potential transient initiator). Since no failure
mode or initiating condition that could cause an accident (including
any plant transient) evaluated per the FSAR [final safety analysis
report]-described safety analyses is created or
[[Page 15790]]
affected, the change cannot involve a significant increase in the
probability of an accident previously evaluated.
With regard to the consequences of an accident and the equipment
required for mitigation of the accident, the proposed changes
involve no design or physical changes to components in the main
steam supply system or feedwater system. There is no impact on the
design safety function of MSIVs, MFIVs, MFRVs, or MFRVBVs or any
other equipment required for accident mitigation. Adequate equipment
availability would continue to be required by the TS. The
consequences of applicable, analyzed accidents (such as a main steam
line break of feedline break) are not impacted by the proposed
changes.
The change in APPLICABILITY for the MSIVs is consistent with the
Westinghouse Standard Technical Specification 3.7.2. The change to
footnote (i) in TS Table 3.3.2-1 makes the provisions of that note
for the affected instrumentation consistent with the revised
APPLICABILITY of TS 3.7.2. These changes involve no physical changes
to the facility and do not adversely affect the availability of the
safety functions assumed for the MSIVs and SSIVs. Therefore, they do
not involve a significant increase in the probability or
consequences of an accident previously evaluated. Based on the above
considerations, the proposed changes do 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 changes add requirements to the TS that support or
ensure the availability of the safety functions assumed or required
for the MSIVs and SSIVs. The changes do not involve a physical
alteration of the plant (no new or different type of equipment will
be installed) or changes in controlling parameters. Additional
requirements are being imposed, but they are consistent with the
assumptions made in the safety analysis and licensing basis. The
addition of Conditions, Required Actions and Completion Times to TS
for the SSIVs does not involve a change in the design,
configuration, or operational characteristics of the plant. Further,
the proposed changes do not involve any changes in plant procedures
for ensuring that the plant is operated within analyzed limits. As
such, no new failure modes or mechanisms that could cause a new or
different kind of accident from any previously evaluated are
introduced.
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?
Response: No.
The proposed addition of Conditions, Required Actions and
Completion Times for SSIVs, as well as the proposed change to the
APPLICABILITY for the MSIV TS (and the corresponding change to the
footnote for the ESFAS Instrumentation in TS 3.3.2) does not alter
the manner in which safety limits or limiting safety system settings
are determined. No changes to instrument/system actuation setpoints
are involved. The safety analysis acceptance criteria are not
impacted and the proposed change will not permit plant operation in
a configuration outside the design basis. The changes are consistent
with the safety analysis and licensing basis for the facility.
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.

Union Electric Company, Docket No. 50-483, Callaway Plant, Unit 1,
Callaway County, Missouri
Date of amendment request: December 28, 2007.
Description of amendment request: The amendment would incorporate
changes in the Technical Specifications (TS). Specifically, a footnote
associated with Table 3.3.2-1 of Technical Specification 3.3.2,
``Engineered Safety Feature Actuation System (ESFAS) Instrumentation,''
would be revised to make the exception allowed by the footnote
consistent with the scope and Applicability of TS 3.7.3, ``Main
Feedwater Isolation Valves (MFIVs) and Main Feedwater Regulating Valves
(MFRVs) and Main Feedwater Regulating Valve Bypass Valves (MFRVBVs)''
and a Note connected with each of two Surveillance Requirements (SRs),
i.e., SR 3.7.2.1 and SR 3.7.2.2 under TS 3.7.2, ``Main Steam Isolation
Valves (MSIVs),'' would be deleted as it is no longer needed or
appropriate for the affected SRs.
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
Overall protection system performance will remain within the
bounds of the previously performed accident analyses since there are
no design changes. All design, material, and construction standards
that were applicable prior to this amendment request will be
maintained. There will be no changes to any design or operating
limits.
The proposed changes will not change accident initiators or
precursors assumed or postulated in the final safety analysis report
(FSAR)-described accident analyses, nor will they alter the design
assumptions, conditions, and configuration of the facility or the
manner in which the plant is operated and maintained. The proposed
changes will not alter or prevent the ability of structures,
systems, and components (SSCs) from performing their intended
functions to mitigate the consequences of an initiating event within
the assumed acceptance limits.
The proposed changes do not physically alter safety-related
systems, nor do they affect the way in which safety-related systems
perform their functions.
All accident analysis acceptance criteria will continue to be
met with the proposed changes. The proposed changes will not affect
the source term, containment isolation, or radiological release
assumptions used in evaluating the radiological consequences of an
accident previously evaluated. The proposed changes will not alter
any assumptions or change any mitigation actions in the radiological
consequence evaluations in the FSAR. The applicable radiological
dose acceptance criteria will continue to be met.
Therefore, the proposed changes do 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
There are no proposed design changes, nor are there any changes
in the method by which any safety-related plant structure, system,
or component (SSC) performs its specified safety function. The
proposed changes will not affect the normal method of plant
operation or change any operating parameters. No equipment
performance requirements will be affected. The proposed changes will
not alter any assumptions made in the safety analyses.
No new accident scenarios, transient precursors, failure
mechanisms, or limiting single failures will be introduced as a
result of this amendment. There will be no adverse effect or
challenges imposed on any safety-related system as a result of this
amendment.
The proposed amendment will not alter the design or performance
of the 7300 Process Protection System, Nuclear Instrumentation
System, or Solid State Protection System used in the plant
protection systems.
Therefore, the proposed changes do not create the possibility of
a new or different accident from any accident previously evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No
There will be no effect on those plant systems necessary to
assure the accomplishment of protection functions.
[[Page 15791]]
There will be no impact on the overpower limit, departure from
nucleate boiling ratio (DNBR) limits, heat flux hot channel factor
(FQ), nuclear enthalpy rise hot channel factor (FAH), loss of
coolant accident peak cladding temperature (LOCA PCT), peak local
power density, or any other margin of safety. The applicable
radiological dose consequence acceptance criteria for design-basis
transients and accidents will continue to be met.
The proposed changes do not eliminate any surveillance or alter
the frequency of surveillances required by the Technical
Specifications. None of the acceptance criteria for any accident
analysis will be changed.
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.

Description of amendment request: The proposed amendment would
revise Technical Specification (TS) 3.4.10, ``Pressurizer Safety
Valves,'' and TS 3.4.11, ``Pressurizer Power Operated Relief Valves
(PORVs),'' to modify the completion times for default conditions in
both TSs and to allow separate condition entry for PORV block valves in
TS 3.4.11. The amendment request is adopting the following two Nuclear
Regulatory Commission (NRC)-approved TS Task Force (TSTF) travelers to
the standard TSs: TSTF-247-A and TSTF-352-A.
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. [Do] the proposed change[s] involve a significant increase in

Response: No.
Overall protection system performance will remain within the
bounds of the previously performed accident analyses since there are
no design changes. All design, material, and construction standards
that were applicable prior to this amendment request will be
maintained. There will be no changes to the design and operating
temperature and pressure limits placed on the reactor coolant
system.
The proposed changes will not adversely affect accident
initiators or precursors nor alter the design assumptions,
conditions, and configuration of the facility or the manner in which
the plant is operated and maintained. The proposed changes will not
alter or prevent the ability of structures, systems, and components
(SSCs) from performing their intended functions to mitigate the
consequences of an initiating event within the assumed acceptance
limits.
The proposed changes do not physically alter safety-related
systems nor affect the way in which safety-related systems perform
their functions.
All accident analysis acceptance criteria will continue to be

for the plant]. The applicable radiological dose acceptance criteria
will continue to be met.
Therefore, the proposed changes do not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. [Do] the proposed change[s] create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
There are no proposed design changes nor are there any changes
in the method by which any safety-related plant SSC performs its
safety function. The proposed changes will not affect the normal
method of plant operation or change any operating parameters. No
equipment performance requirements will be affected. The proposed
changes will not alter any assumptions made in the safety analyses.

(DNBR) limits, heat flux hot channel factor (FQ), nuclear enthalpy
rise hot channel factor (F[Delta]H), loss of coolant accident peak
cladding temperature (LOCA PCT), peak local power density, or any
other margin of safety. The applicable radiological dose consequence
acceptance criteria will continue to be met. The proposed changes do
not eliminate any surveillances or alter the frequency of
surveillances required by the Technical Specifications. None of the
acceptance criteria for any accident analysis will be changed.
The proposed changes will have no impact on the radiological
consequences of a design basis accident.
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

Brief description of amendment: The amendment changes the NMP2
Technical Specifications to reflect an expanded operating domain
resulting from implementation of Average Power Range Monitor/Rod Block
Monitor/Technical Specifications/Maximum Extended Load Line Analysis
(ARTS/MELLLA). The Average Power Range Monitor (APRM) flow-biased
simulated thermal power allowable value (AV) would be revised to permit
operation in the MELLLA region. The current flow-biased Rod Block
Monitor (RBM) would be replaced by a power dependent RBM, which also
would require new AVs. The flow-biased APRM simulated thermal power
setdown requirement would be replaced by more direct power and flow
dependent thermal limits administration. The Surveillance Requirement
for the standby liquid control (SLC) system would be revised to require
each SLC pump to deliver required flow at a discharge pressure >=1325
psig in lieu of >=1320 psig; the SLC relief valve setpoint would be
increased from 1394 psig to 1400 psig. Finally, the proposed amendment
employs a new model for performing the anticipated transients without
scram analysis for ARTS/MELLLA conditions.
