Notice of Consideration of Issuance of Amendments to Facility Operating
Licenses and Combined 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) 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; (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.
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 or
combined license. Requests for a
[[Page 25754]]
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 NRC's
PDR, located at One White Flint North, Room O1-F21, 11555 Rockville
Pike (first floor), Rockville, Maryland 20852. NRC regulations are
accessible electronically from the NRC Library on the NRC's Web site at
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 requestor/petitioner
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
requestor/petitioner 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 requestor/
petitioner intends to rely in proving the contention at the hearing.
The requestor/petitioner must also provide references to those specific
sources and documents of which the petitioner is aware and on which the
requestor/petitioner 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 requestor/petitioner to relief. A requestor/
petitioner 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 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, then any hearing
held would take place before the issuance of any amendment.
All documents filed in the 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's E-Filing rule (72 FR 49139,
August 28, 2007). 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 10
days prior to the filing deadline, the participant should contact the
Office of the Secretary by email at [email protected], or by
telephone at 301-415-1677, to request (1) a digital identification (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 (2) advise
the Secretary that the participant will be submitting a request or
petition for hearing (even in instances in which the participant, or
its counsel or representative, already holds an NRC-issued digital ID
certificate). Based upon this information, the Secretary will establish
an electronic docket for the hearing in this proceeding if the
Secretary has not already established an electronic docket.
Information about applying for a digital ID certificate is
available on the NRC's public Web site at http://www.nrc.gov/site-help/e-submittals/apply-certificates.html. System requirements for accessing
the E-Submittal server are detailed in the NRC's ``Guidance for
Electronic Submission,'' which is available on the agency's public Web
site at http://www.nrc.gov/site-help/e-submittals.html. Participants
may attempt to use other software not listed on the Web site, but
should note that the NRC's E-Filing system does not support unlisted
software, and the NRC Meta System Help Desk will not be able to offer
assistance in using unlisted software.
If a participant is electronically submitting a document to the NRC
in accordance with the E-Filing rule, the participant must file the
document using the NRC's online, Web-based submission form. In order to
serve documents through the Electronic Information Exchange System,
users will be required to install a Web browser plug-in from the NRC's
Web site. Further information on the Web-based submission form,
including the installation of the Web browser plug-in, is available on
the NRC's public Web site at http://www.nrc.gov/site-help/e-submittals.html.
Once a participant has obtained a digital ID certificate and a
docket has been created, the participant can then submit a request for
hearing or petition for leave to intervene. Submissions should be in
Portable Document Format (PDF) in accordance with the NRC guidance
available on the NRC's public Web site at http://www.nrc.gov/site-help/e-submittals.html. A filing is considered complete at the time the
documents are submitted through the NRC's E-Filing system. To be
timely, an electronic filing must be submitted to the E-Filing 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 email notice confirming receipt of the document. The
[[Page 25755]]
E-Filing system also distributes an email notice that provides access
to the document to the NRC's 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 by contacting the NRC Meta System
Help Desk through the ``Contact Us'' link located on the NRC's Web site
at http://www.nrc.gov/site-help/e-submittals.html, by email at
[email protected], or by a toll-free call at 1-866 672-7640. The
NRC Meta System Help Desk is available between 8 a.m. and 8 p.m.,
Eastern Time, Monday through Friday, excluding government holidays.
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. A presiding officer,
having granted an exemption request from using E-Filing, may require a
participant or party to use E-Filing if the presiding officer
subsequently determines that the reason for granting the exemption from
use of E-Filing no longer exists.
Documents submitted in adjudicatory proceedings will appear in the
NRC's electronic hearing docket which is available to the public at
http://ehd1.nrc.gov/ehd/, unless excluded pursuant to an order of the
Commission, or the 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 submission.
Petitions for leave to intervene must be filed no later than 60
days from the date of publication of this notice. Non-timely filings
will not be entertained absent a determination by the presiding officer
that the petition or request should be granted or the contentions
should be admitted, based on a balancing of the factors specified in 10
CFR 2.309(c)(1)(i)-(viii).

Detroit Edison, Docket No. 50-341, Fermi 2, Monroe County, Michigan
Date of amendment request: January 10, 2012.
Description of amendment request: The proposed amendment would
modify Fermi 2 Plant Operating License, Appendix A, Technical
Specifications (TS) to revise the Residual Heat Removal (RHR)
Suppression Pool Cooling Surveillance Requirement (SR) 3.6.2.3.2, flow
requirement from greater than or equal to 10,000 gallons per minute
(gpm) to greater than or equal to 9,250 gpm. This change is consistent
with the RHR suppression cooling rate associated with RHR heat
exchanger minimum thermal performance requirements. Additionally, the
proposed license amendment clarifies that SR 3.6.2.3.2 applies only to
pumps required for meeting the Limiting Condition of Operation.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
The proposed TS SR 3.6.2.3.2 minimum flow of greater than or
equal to 9,250 gpm is consistent with that assumed for accident
extrapolation calculations of measured thermal performance obtained
during RHR heat exchanger testing. This testing is performed to
periodically demonstrate that the actual heat exchanger thermal
performance exceeds that assumed for establishing the maximum post-
accident bulk average suppression pool temperature. Therefore, the
change in required RHR suppression pool cooling flow will not result
in any increase in post-accident suppression pool temperature above
that already evaluated for demonstrating adequate Net Pump Suction
Head (NPSH) for any Emergency Core Cooling System (ECCS) pump. The
change in the applicability of the surveillance to each required RHR
pump provides consistency with the design of the system and
maintains full capability of each RHR suppression pool cooling
subsystem to provide post accident design basis cooling.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
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 revises TS SR 3.6.2.3.2 for RHR suppression
pool cooling flow to be consistent with that assumed for evaluating
measured heat exchanger thermal performance against the minimum
requirements of the plant safety analysis. Changing the
applicability of the surveillance to each required RHR pump is
consistent with the system design requirement and maintains full
capability of each RHR suppression pool cooling subsystem to provide
the post accident cooling function. No physical changes are being
made to the installed RHR system or the manner in which it is
operated. No new or different accident scenarios are created by this
change.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any accident previously
evaluated.
3. The proposed change does not involve a significant reduction
in the margin of safety.
The RHR system has historically been capable of meeting TS SR
3.6.2.3.2. This Surveillance requires demonstration of a system
flow, in conjunction with a prescribed RHR heat exchanger capacity
that ensures the overall suppression pool cooling capacity meets the
requirements of the safety
[[Page 25756]]
analysis. However, the lack of available operating margin inherent
in the design orifices of the RHR suppression pool cooling test
return line and identification of a non-conservative bias in the
test flow instrument calibration have eroded the flow test margin
such that it is possible that the TS SR may not be satisfied in the
future even though a large margin is maintained compared to the
minimum performance assumed in the containment safety analyses. The
proposed change makes the margin between TS SR 3.6.2.3.2 and the
performance assumed in the plant safety analyses available as a
design and operating margin. This is ensured by establishing a
higher level of required heat exchanger performance, where ample
margin is available. Heat exchanger testing is conducted in
accordance with existing testing standards as prescribed by EPRI TR-
107397, Service Water Heat Exchanger Testing Guidelines. The minimum
required flow rate necessary to satisfy RHR suppression pool cooling
TS SR 3.6.2.3.2 will be documented in the plant design basis with
the minimum required flow adjusted upward as necessary to account
for instrument uncertainty and bias as well as differences between
assumed accident and actual test operating conditions.
The change in the applicability of the surveillance to each
required RHR pump is consistent with the design basis of the plant
and maintains full capability of the system to provide its safety
related cooling function following a design basis accident.
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.

Detroit Edison, Docket No. 50-341, Fermi 2, Monroe County, Michigan
Date of amendment request: January 10, 2012.
Description of amendment request: The proposed amendment would
modify Fermi 2 Plant Operating License, Appendix A, Technical
Specifications (TS) to modify Surveillance Requirement (SR) 3.4.3.2, in
TS 3.4.3, ``Safety Relief Valves (SRVs)'', SR 3.5.1.13, in TS 3.5.1,
``ECCS-Operating,'' and SR 3.6.1.6.1, in TS 3.6.1.6, ``Low-Low Set
(LLS) Valves.'' This proposed amendment replaces the current
requirement in these TS SRs to verify the SRV opens when manually
actuated with an alternate requirement that verifies the SRV is capable
of being opened. The verification of that capability would be satisfied
by a series of overlapping tests, performed during a refueling outage,
that demonstrate the required functions of successive valve stages.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed change does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
The proposed change does not modify the method of demonstrating
the operability of the Safety Relief Valves (SRVs) in both the
safety and relief modes of operation. As currently stated in the
Technical Specification (TS) Bases ``* * * valve OPERABILITY and the
setpoints for overpressure protection are verified, per ASME Code
requirements, prior to valve installation.'' The proposed change
does modify the method for demonstrating the proper mechanical
functioning of the SRVs. The SRVs are required to function in the
safety mode to prevent overpressurization of the reactor vessel and
reactor coolant system pressure boundary during various analyzed
transients, including Main Steam Isolation Valve closure. SRVs
associated with the Automatic Depressurization System are also
required to function in the relief mode to reduce reactor pressure
to permit injection by low pressure Emergency Core Cooling System
(ECCS) pumps during certain reactor coolant pipe break accidents.
The current testing method demonstrates the proper mechanical
functioning of the SRVs in both modes through manual actuation of
the SRVs. The proposed new testing method demonstrates both
operability and proper mechanical functioning using a series of
overlapping tests that demonstrate proper functioning of the SRV and
supporting control components. This proposed testing method results
in acceptable demonstration of the SRV functions in both the safety
and relief modes, and therefore provides assurance that the
probability of SRV failure will not increase. None of the accident
safety analyses is affected by the requested TS changes. Therefore,
the consequences of accidents mitigated by the SRVs will not
increase.
Certain SRV malfunctions are included in the UFSAR safety
analyses. Specifically, the plant safety analyses include the
inadvertent opening of an SRV and a stuck open SRV. By reducing or
not actuating the SRVs during plant operation for testing and thus
reducing the potential incidence of pilot stage leakage of the SRVs,
the proposed testing reduces a contributor to these events.
Based on these considerations, the proposed test method does not
involve a significant increase in the probability or consequences of
an accident previously evaluated.
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 modifies the method of testing of the SRVs,
but does not alter the functions or functional capabilities of the
SRVs. Testing under the proposed method is performed in offsite test
facilities and in the plant during outage periods when the SRV
functions are not required. Existing analyses address events
involving an SRV inadvertently opening or failing to reclose.
Analyses also address the failure of one or more SRVs to open. The
proposed change does not introduce any new failure mode, and
therefore, does not create the possibility of a new or different
kind of accident from any accident previously evaluated.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any accident previously
evaluated.
3. The proposed change does not involve a significant reduction
in the margin of safety.
The proposed amendment provides for an alternative means of
testing the SRVs. The proposed changes will provide a complete
verification of the functional capability of the SRVs by performing
a series of tests, inspections, and maintenance activities without
opening the valves with reactor steam while installed in the plant.
The alternative testing and associated programmatic controls will
provide an equivalent level of assurance that the SRVs are capable
of performing their intended accident mitigation safety functions.
The proposed amendment does not affect the valve setpoints or
adversely affect any other operational criteria assumed for accident
mitigation. No changes are proposed that alter the setpoints at
which protective actions are initiated, and there is no change to
the operability requirements for equipment assumed to operate for
accident mitigation. Moreover, it is expected that the alternative
testing methodology will increase the margin of safety by reducing
the potential for SRV leakage resulting from testing the SRVs with
reactor steam pressure while installed in the plant.
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.

Duke Energy Carolinas, LLC, Docket Nos. 50-269, 50-270, and 50-287,
Oconee Nuclear Station, Units 1, 2, and 3, Oconee County, South
Carolina
Date of amendment request: September 20, 2011, as supplemented by
letter dated November 21, 2011.
Description of amendment request: The proposed amendments would
allow revisions to the current licensing basis to allow a measurement
uncertainty recapture (MUR) power uprate.
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 changes the rated thermal power from 2568
megawatts thermal (MWt) to 2610 MWt; an increase of approximately
1.64% Rated Thermal Power. Duke Energy's evaluations have shown that
all structures, systems and components (SSCs) are capable of
performing their design function at the uprated power of 2610 MWt. A
review of station accident analyses found that all but two analyses
remain bounding at the uprated power of 2610 MWt. These two analyses
(High Energy Line Break and Double Main Steam Line Break) were
reanalyzed at the higher power level and found to be acceptable.
The radiological consequences of operation at the uprated power
conditions have been assessed. The proposed power uprate does not
affect release paths, frequency of release, or the analyzed reactor
core fission product inventory for any accidents previously
evaluated in the Final Safety Analysis Report. Analyses performed to
assess the effects of mass and energy releases remain valid. All
acceptance criteria for radiological consequences continue to be met
at the uprated power level.
As summarized in Sections IV, V, and VI of Enclosure 2, the
proposed change does not involve any change to the design or
functional requirements of the associated systems. That is, the
increased power level neither degrades the performance of, nor
increases the challenges to any safety systems assumed to function
in the plant safety analysis.
While power level is an input to accident analyses, it is not an
initiator of accidents. The proposed change does not affect any
accident precursors and does not introduce any accident initiators.
The proposed change does not impact the usefulness of the
Surveillance Requirements (SRs) in evaluating the operability of
required systems and components.
In addition, evaluation of the proposed TS [Technical
Specification] change demonstrates that the availability of
equipment and systems required to prevent or mitigate the
radiological consequences of an accident is not significantly
affected. Since the impact on the systems is minimal, it is
concluded that the overall impact on the plant safety analysis is
negligible.
Therefore, the proposed TS changes do not significantly increase
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.
A Failure Modes and Effects Analysis of the new system was
performed, and the possible effects of failures of the new equipment
and the increased power level on the overall plant systems were
reviewed. This review found that no new or different accidents were
created by the new equipment or the uprated power levels.
No installed equipment is being operated in a different manner.
The proposed changes have no significant adverse affect on any
safety-related SSCs and do not significantly change the performance
or integrity of any safety-related system.
The proposed changes do 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 previously
evaluated. The uprated power does not create any new accident
initiators. Credible malfunctions are bounded by the current
accident analyses of record or recent evaluations demonstrating that
applicable criteria are still met with the proposed changes.
Therefore, this change 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.
Although the proposed amendment increases the operating power
level of the plants, it retains the margin of safety because it is
only increasing power by the amount equal to the reduction in
uncertainty in the heat balance calculation. The margins of safety
associated with the power uprate are those pertaining to core
thermal power. These include fuel cladding, reactor coolant system
pressure boundary, and containment barriers. Analyses demonstrate
that the current design basis continues to be met after the MUR
power uprate. Components associated with the reactor coolant system
pressure boundary structural integrity, including pressure-
temperature limits, vessel fluence, and pressurized thermal shock
are bounded by the current analyses. Systems will continue to
operate within their design parameters and remain capable of
performing their intended safety functions.
The current Oconee safety analyses, and the revised design basis
radiological accident dose calculations, bound the power uprate and
therefore do not significantly impact margins.
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 Gulf States Louisiana, LLC, and Entergy Operations, Inc.,
Docket No. 50-458, River Bend Station, Unit 1, West Feliciana Parish,
Louisiana
Date of amendment request: December 8, 2011.
Description of amendment request: The amendment would revise
Technical Specifications (TS) 3.8.1; ``AC [Alternating Current]
Sources--Operating.'' Specifically, the amendment would revise TS 3.8.1
and the associated Bases, to expand its scope to include provisions for
testing of the automatic transfer function from the station 22 kiloVolt
(kV) bus to offsite power for Division III. A new Surveillance
Requirement (SR) would be added to ensure availability of offsite power
after loss of the station (onsite) 22 kV bus when offsite power remains
available. The amendment would also add notes to the Limiting Condition
for Operation (LCO) and SR to require this feature when Division III is
powered by onsite power. In addition, new ACTIONS would be added to
ensure this transfer from onsite to offsite is maintained when a
required offsite power source is lost.
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 revises the Technical Specification
Surveillance Requirements to allow power for emergency systems to be
supplied from onsite power prior to event initiation. This power
supply will be transferred to the current accepted offsite power
source if the main generator is no longer available. The proposed
Surveillance Requirement is to confirm the automatic transfer
function.
The proposed changes do not involve a change in the design
requirements of the electrical power systems, including the
emergency power systems. The plant will continue to operate within
acceptable parameters (electrical loading, etc.) The
[[Page 25758]]
proposed changes do not change the function of plant equipment, or
affect the response of emergency power systems.
The proposed changes do not involve a change in the design basis
initiators for loss of offsite power to the emergency power systems.
The proposed change utilizes existing components and circuits. The
change will add a new surveillance requirement to confirm the design
function operation.
The proposed change does not impact other design basis accident
initiators or analyzed events or assumed mitigation of accident or
transient events.
The proposed change does not involve a change to the
consequences of a design basis event as described in the Safety
Analysis Report.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The proposed change revises the Technical Specification
surveillance requirements to confirm operation of existing
components and circuits. The proposed changes do not involve a
change in the design basis initiators for loss of offsite power to
the emergency power systems.
The proposed changes do not involve a change in the design
requirements of the electrical power systems, including the
emergency power systems. The proposed changes do not change the
function of plant equipment, nor do they affect the response of
emergency power systems.
The proposed changes do not involve a change in the operational
limits or physical design of the electrical power systems,
particularly the emergency power systems. The proposed changes do
not change the design function or operation of plant equipment, nor
do they introduce any new failure mechanisms. This change will
implement surveillance requirements to confirm the design function
operation.
The transfer function components supporting the safety-related
buses have been designed to applicable quality standards and design
criteria. As such, no new failure modes are being introduced. The
plant equipment will continue to respond in accordance with the
design and analyses, and no malfunction of a new or different type
is being introduced by the proposed changes.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The proposed change revises the Technical Specification
surveillance requirements. The proposed changes do not involve a
change in the operational limits or the response of that equipment
if it is called upon to operate.
The performance capability of the emergency diesel generators
will not be affected. The plant will continue to operate within
acceptable parameters (electrical loading, etc.)[.]
In addition, administrative controls will ensure there are
adequate administrative controls are in place to ensure the plant
configuration remains as evaluated.
The results of the PRA performed to quantitatively assess the
risk impact of this change indicate there is a minimal risk impact.
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. 50-247, Indian Point
Nuclear Generating Unit 2, Westchester County, New York
Date of amendment request: January 11, 2012.
Description of amendment request: The proposed amendment would
modify Technical Specification (TS) Table 3.3.6-1, ``Containment Purge
System and Pressure Relief Line Isolation Instrumentation.'' The
proposed amendment would change the term ``ALLOWABLE VALUE'' to ``TRIP
SETPOINT'' and revise the current setpoint used for the Containment
Purge Systems and Pressure Relief Line isolation. The proposed revision
to TS Table 3.3.6-1 will change ``<= 3 x background'' to allow the trip
setpoint to be as specified in the Offsite Dose Calculation Manual
(ODCM).
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 will revise the term ``ALLOWABLE VALUE'' to
``TRIP SETPOINT'' and change the setpoint requirements from ``<= 3
[x] background'' to allow the allowable value to be as specified in
the Offsite Dose Calculation Manual (ODCM). The change to trip
setpoint is a correction of an administrative error and will only
affect the instrument setting specified. Therefore it does not
involve the initiation of an accident or the consequences. The
values for the instrument setting are provided for isolating the
Containment Purge and Pressure Relief Systems due to increased
source terms and are redundant to containment isolation signals.
They have no effect on the probability of an accident previously
evaluated. The change in the setting will be negligible for purposes
of an accident termination. The ODCM limits are based on 10 CFR 20
[Title 10 of the Code of Federal Regulations, Part 20] limits which
are substantially below accident analysis release rates. Therefore
the change has a minimum effect on the consequences of such
accidents.
Therefore, the proposed changes do not involve a significant
increase in the probability or consequences of previously evaluated
accidents.
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 change will revise the term ``ALLOWABLE VALUE'' to
``TRIP SETPOINT'' and change the setpoint requirements. The changes
do not affect the system operations, plant operating procedures or
affect how the plant is operated. The change does not create the
possibility of any equipment failure or effect on other equipment.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The proposed change will revise the term ``ALLOWABLE VALUE'' to
``TRIP SETPOINT'' and change the setpoint requirements. The change
to trip setpoint is correcting an administrative error and has no
significant affect on the margin of safety. The proposed change
involves changes to existing setpoints for automatic isolation of
the Containment Purge and Pressure Relief Systems. However, the
ability of the systems to isolate remains within current evaluations
and therefore does not significantly reduce the safety margin.
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.

Northern States Power Company--Minnesota, Docket No. 50-263, Monticello
Nuclear Generating Plant (MNGP), Wright County, Minnesota
Date of amendment request: April 5, 2012.
Description of amendment request: The licensee proposed to revise
the MNGP Technical Specifications (TS) 3.3.5.1, ``Emergency Core
Cooling System (ECCS) Instrumentation.'' Specifically, it is proposed
to revise the lower allowable value limit for Table 3.3.5.1, Functions
1.e and 2.e, ``Reactor Steam Dome Pressure Permissive--Bypass Timer
(Pump Permissive).'' The licensee has determined that the upper
allowable value limit for the Automatic Depressurization System (ADS)
bypass timer function provides the operator sufficient time to assess
the situation and inhibit ADS actuation if the event does not require
rapid reactor depressurization. The lower allowable value limit ADS
bypass timer function pertains to providing adequate margin to unwanted
pump starts during reactor water level transients and is not credited
in the safety analyses.
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 (NSHC). The NRC staff reviewed the licensee's NSHC
analysis and prepared its own as follows:
(1) Does the proposed amendment involve a significant increase
in the probability or consequences of an accident previously
evaluated?
Response: No.
The proposed change does not physically impact the plant nor
does it impact any design or functional requirements of the
Automatic Depressurization System (ADS). The proposed change does
not degrade the performance or increase the challenges to any safety
systems assumed to function in the accident analysis. There is no
change to normal plant operating parameters or accident mitigation
performance.
Therefore, the proposed amendment 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.
There are no hardware changes nor are there any changes in the
method by which plant systems perform a safety function. This
request does not affect the normal method of plant operation. No new
equipment is introduced which could create a new or different kind
of accident. No new equipment failure modes are created. No new
accident scenarios, transient precursors, failure mechanisms, or
limiting single failures are introduced.
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 amendment does not affect the assumptions of the
safety analysis or the availability or operability of any plant
equipment. There is no reduction in the margin of safety because the
criteria for the performance of the ADS are not changed and there
are no changes to those plant systems necessary to assure the
accomplishment of protection functions.
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
its own analysis, it appears that the three standards of 10 CFR
50.92(c) are satisfied. Therefore, the NRC staff proposes to determine
that the proposed amendment involves no significant hazards
consideration.
