calculational methodology of CE NPSD–
683–A, Revision 6, as described, would
provide an adequate margin of safety
against brittle failure of the RPV.
Therefore, the staff concludes that the
exemption is appropriate under the
special circumstances of 10 CFR
50.12(a)(2)(ii), and that the application
of the KIm calculational methodology of
CE NPSD–683–A, Revision 6, is
acceptable for use as the basis for
generating the St. Lucie, Unit 1, P–T
limits.
4.0 Conclusion
Accordingly, the Commission has
determined that, pursuant to 10 CFR
50.12(a), the exemption is authorized by
law, will not present an undue risk to
the public health and safety, and is
consistent with the common defense
and security. Also, special
circumstances are present. Therefore,
the Commission hereby grants FPL an
exemption from the requirements of 10
CFR Part 50, Appendix G, to allow
application of the KIm calculational
methodology of CE NPSD–683–A,
Revision 6, as the basis for the St. Lucie,
Unit 1, P–T limits.
Pursuant to 10 CFR 51.32, the
Commission has determined that the
granting of this exemption will not have
a significant effect on the quality of the
human environment (76 FR 53497;
dated August 26, 2011). This exemption
is effective upon issuance.
Dated at Rockville, Maryland, this 5th day
of December 2011.

Notice of Consideration of Issuance of
Amendments to Facility Operating
Licenses, Proposed No Significant
Hazards Consideration Determination
and Opportunity for a Hearing
The Commission has made a
proposed determination that the
following amendment requests involve
no significant hazards consideration.
Under the Commission’s regulations in
Title 10 of the Code of Federal
Regulations (10 CFR) 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 60day 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

13DEN1
srobinson on DSK4SPTVN1PROD with NOTICES
77566
Federal Register / Vol. 76, No. 239 / Tuesday, December 13, 2011 / Notices
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.
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 NRC’s PDR, located at
One White Flint North, Room O1–F21,
11555 Rockville Pike (first floor),
Rockville, Maryland 20874. NRC
regulations are accessible electronically
from the NRC Library on the NRC Web
site at https://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
VerDate Mar<15>2010
16:25 Dec 12, 2011
Jkt 226001
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 NRC
adjudicatory proceedings, including a
request for hearing, a petition for leave
to intervene, any motion or other
document filed in the proceeding prior
to the submission of a request for
hearing or petition to intervene, and
documents filed by interested
governmental entities participating
under 10 CFR 2.315(c), must be filed in
accordance with the NRC E-Filing rule
(72 FR 49139, August 28, 2007). The EFiling process requires participants to
submit and serve all adjudicatory
documents over the internet, or in some
cases to mail copies on electronic
PO 00000
Frm 00097

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
hearing.docket@nrc.gov, 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 ESubmittal 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 NRCissued 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 https://
www.nrc.gov/site-help/e-submittals/
apply-certificates.html. System
requirements for accessing the ESubmittal server are detailed in the
NRC’s ‘‘Guidance for Electronic
Submission,’’ which is available on the
agency’s public Web site at https://
www.nrc.gov/site-help/esubmittals.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 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 https://www.nrc.gov/site-help/esubmittals.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

(PDF) in accordance with NRC guidance
available on the NRC public Web site at
https://www.nrc.gov/site-help/esubmittals.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
E-Filing system also distributes an email
notice that provides access to the
document to the NRC Office of the
General Counsel and any others who
have advised the Office of the Secretary
that they wish to participate in the
proceeding, so that the filer need not
serve the documents on those
participants separately. Therefore,
applicants and other participants (or
their counsel or representative) must
apply for and receive a digital ID
certificate before a hearing request/
petition to intervene is filed so that they
can obtain access to the document via
the E-Filing system.
A person filing electronically using
the agency’s adjudicatory E-Filing
system may seek assistance by
contacting the NRC Meta System Help
Desk through the ‘‘Contact Us’’ link
located on the NRC Web site at https://

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

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 https://
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. Nontimely 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).

Description of amendment request:
The proposed amendment involves
administrative changes. The proposed
changes include correcting
typographical errors, removing
unwarranted formatting, clarifying
symbols and pages, reformatting of
previously deleted pages, incorporating
a consistent abbreviation of average
reactor coolant temperature, deleting
notes that are no longer applicable, and
replacing certain drawing figures with
versions that are more clear.
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, with NRC edits in brackets:
1. Does the proposed change involve a
significant increase in the probability or
consequences of an accident previously
evaluated?
Response: No.
No physical changes to the facility will
occur as a result of this proposed
amendment. The proposed changes will not
alter the physical design or operational
procedures associated with any plant
structure, system, or component. The
proposed changes are administrative in
nature and have no affect on plant operation.
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.
The proposed changes are administrative
in nature. The proposed changes do not alter
the physical design, safety limits, or safety
analysis assumptions associated with the
operation of the plant. Accordingly, the
changes do not introduce any new accident
initiators, nor do they reduce or adversely
affect the capabilities of any plant structure,
system, or component to perform their safety
function.
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 change involve a
significant reduction in a margin of safety?
Response: No.
The proposed changes [maintain
compliance with the requirements contained
in 10 CFR 50.36, ‘‘Technical specifications.’’]
The proposed changes are administrative in
nature. The proposed changes do not alter
the physical design, safety limits, or safety
analysis assumptions associated with the
operation of the plant.
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, with the NRC edits above, it
E:\FR\FM\13DEN1.SGM

Description of amendment request:
The proposed amendments would make
changes to the diesel fuel oil license
bases and amend technical
specifications (TS) 3.7.8, ‘‘Cooling
Water (CL) System’’ and 3.8.3, ‘‘Diesel
Fuel Oil.’’ The proposed TS changes
would revise current requirements to
reflect the addition of the license bases,
resolve non-conservative emergency
diesel generator fuel oil supply
volumes, incorporate portions of
Technical Specification Task Force
Traveler 501, ‘‘Relocate Stored Fuel Oil
and Lube Oil Volume Values to
Licensee Control,’’ and provide
administrative changes to the TS.
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.
This license amendment request proposes
addition of a diesel fuel oil supply license
basis and revision of the associated Technical
Specifications to require an adequate
emergency diesel generator and diesel driven
cooling water pump fuel oil supply for
mitigation of a design basis accident with a
loss of offsite power. This license
amendment request also proposes to: adopt
provisions of Technical Specifications Task
Force (TSTF) industry traveler 501 (TSTF–
501) to specify diesel fuel oil supply
requirements as required days for the supply
and relocate the corresponding volume to the
Technical Specification Bases; and, make
minor wording changes to improve
conformance to the content guidance of
NUREG–1431, ‘‘Standard Technical
Specifications, Westinghouse Plants.’’
The emergency diesel generators, diesel
driven cooling water pumps and their
supporting diesel fuel oil storage systems are
VerDate Mar<15>2010

Jkt 226001
not accident initiators and therefore the
proposed diesel fuel oil supply license basis
addition and proposed Technical
Specification changes do not involve an
increase in the probability of an accident.
The proposed change to the emergency
diesel generator fuel oil supply license basis
and the associated Technical Specification
changes will assure that the emergency diesel
generator’s diesel driven cooling water
pumps perform their required design basis
accident mitigation safety function with a
loss of offsite power. Since the emergency
diesel generators will provide required
electrical power as assumed in the accident
analyses and the cooling water diesel will
provide cooling water as assumed in the
accident analyses, the results of the previous
accident analyses are not changed and the
license basis changes proposed in this license
amendment request do not involve a
significant increase in the consequences of an
accident.
Specification of the diesel fuel oil supply
requirements as required days supply in
accordance with TSTF–501 continues to
assure an adequate quantity of diesel fuel oil
is required to be stored; the emergency diesel
generators and diesel driven cooling water
pumps will have sufficient diesel fuel oil to
mitigate a design basis accident with a loss
of offsite power, as assumed in the accident
analyses, until the fuel supply can be
replenished; and therefore, this change does
not involve a significant increase in the
consequences of an accident.
The proposed minor Technical
Specification wording changes to improve
alignment with the content guidance of
NUREG–1431 are administrative and thus do
not involve an increase in the consequences
of an accident.
Therefore, 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.
This license amendment request proposes
addition of a diesel fuel oil supply license
basis and revision of the associated Technical
Specifications to require an adequate
emergency diesel generator and diesel driven
cooling water pump fuel oil supply for
mitigation of a design basis accident with a
loss of offsite power. This license
amendment request also proposes to: adopt
provisions of Technical Specifications Task
Force (TSTF) industry traveler 501 (TSTF–
501) to specify diesel fuel oil supply
requirements as required days for the supply
and relocate the corresponding volume to the
Technical Specification Bases; and, make
minor wording changes to improve
conformance to the content guidance of
NUREG–1431, ‘‘Standard Technical
Specifications, Westinghouse Plants.’’
The proposed diesel fuel oil supply license
basis change and the associated Technical
Specification changes assure that each
emergency diesel generator and diesel driven
cooling water pump has an adequate supply
of diesel fuel oil, assuming an active single

failure, to mitigate a design basis accident
with a loss of offsite power until the fuel oil
supply can be replenished. The proposed
license basis change and associated
Technical Specification changes do not
create new failure modes or mechanisms and
no new accident precursors are generated.
The proposed specification of the diesel fuel
oil supply requirements as required days
supply in accordance with TSTF–501 does
not create new failure modes or mechanisms
and does not generate new accident[s]. These
proposed changes do not challenge the
performance or integrity of any safety-related
system. Surveillance requirements for the
emergency diesel generator and diesel driven
cooling water pump fuel oil supplies will
continue to demonstrate that the Limiting
Conditions for Operation are met and the
emergency diesel generators and diesel
driven cooling water pumps have adequate
supplies of diesel fuel oil to perform their
safety functions.
The proposed minor Technical
Specification wording changes to improve
alignment with the content guidance of
NUREG–1431 are administrative and thus do
not create the possibility of a new or different
kind of accident.
Therefore, the proposed changes do 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.
This license amendment request proposes
addition of a diesel fuel oil supply license
basis and revision of the associated Technical
Specifications to require an adequate
emergency diesel generator and diesel driven
cooling water pump fuel oil supply for
mitigation of a design basis accident with a

Force (TSTF) industry traveler 501 (TSTF–
501) to specify diesel fuel oil supply
requirements as required days for the supply
and relocate the corresponding volume to the
Technical Specification Bases; and, make
minor wording changes to improve
conformance to the content guidance of
NUREG–1431, ‘‘Standard Technical
Specifications, Westinghouse Plants.’’
The proposed diesel fuel oil supply
licensing basis addition and the associated
Technical Specification changes involve the
addition of a new requirement to assure that
each emergency diesel generator and diesel
driven cooling water pump has an adequate
supply of diesel fuel oil, assuming an active
single failure, to mitigate a design basis
accident with a loss of offsite power until the
fuel oil supply can be replenished. The
current license basis for mitigation of an
external flood without a single failure will be
maintained. Therefore, margins of safety are
increased and thus no margin of safety is
reduced due to these changes.
Specification of the diesel fuel oil supply
requirements as required days supply in
accordance with TSTF–501 continues to
assure an adequate quantity of diesel fuel oil
is required to be stored and thus does not
reduce a margin of safety.

The proposed minor Technical
Specification wording changes to improve
alignment with the content guidance of
NUREG–1431 are administrative and thus do
not involve a significant reduction in a
margin of safety.
The proposed Technical Specification
changes do not adversely affect the
availability, operability, or performance of
safety-related systems and components: the
emergency diesel generators [and] diesel
driven cooling water pumps will continue to
perform their safety functions. The ability of
operable structures, systems, and
components to perform their designated
safety functions are unaffected by these
proposed changes. The operability
requirements of the proposed Technical
Specifications are consistent with the initial
condition assumptions of the safety analyses,
and the Surveillance requirements for the
emergency diesel generator and diesel driven
cooling water pump fuel oil supplies will
assure that the Limiting Conditions for
Operation are met and the emergency diesel
generator’s diesel driven cooling water
pumps have adequate supplies of diesel fuel
oil to perform their safety functions.
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 requests involve no
significant hazards consideration.

Date of amendment request: June 1,
2011.
Description of amendment request:
The proposed amendment would revise
Technical Specification (TS) 3.7.5,
‘‘Auxiliary Feedwater (AFW) System,’’
TS 3.6.6, ‘‘Containment Spray and
Cooling Systems,’’ TS 3.8.1, ‘‘AC
[Alternating Current] Sources—
Operating,’’ TS 3.8.9, ‘‘Distribution

‘‘Completion Times,’’ Example 1.3–3.
These changes are consistent with
Technical Specification Task Force
(TSTF) Change Travelers TSTF–245,
Revision 1, ‘‘AFW Train Operable when
in Service,’’ TSTF–340, Revision 3,
‘‘Allow 7 day Completion Time for a

AFW/EFW [Emergency Feedwater]
Pump Inoperable,’’ and TSTF–439,
Revision 2, ‘‘Eliminate Second
Completion Times Limiting Time From
Discovery of Failure to Meet an LCO
[Limiting Condition for Operation].’’
Specifically, the changes consistent
with TSTF–245, Revision 1, and TSTF–
340, Revision 3, would revise TS 3.7.5
to clarify the operability of an AFW
train during alternate alignments and
provide added flexibility in Mode 3 to
repair and test the turbine-driven AFW
(TDAFW) pump following a refueling
outage. The changes consistent with
TSTF–412, Revision 3, would revise TS
3.7.5 to establish conditions, required
actions, and completion times for the
condition where one steam supply to
the TDAFW is inoperable concurrent
with an inoperable motor-driven AFW
(MDAFW) train. The TSTF–412,
Revision 3, Notice of Availability was
published in the Federal Register on
July 17, 2007 (72 FR 39089), using the
consolidated line item improvement
process (CLIIP). The changes consistent
with TSTF–439, Revision 2, would
remove second completion times from
TS Example 1.3–3; TS 3.6.6 Required
Actions A.1, A.2, and C.1; TS 3.7.5
Required Actions A.1 and B.1; TS 3.8.1
Required Actions A.2 and B.4; and TS
3.8.9 Required Actions A.1, B.1, and
C.1. In addition, the amendment would
add a new Condition B, required
actions, and completion times to TS
3.7.5 to provide specific actions to be
taken when automatic control of the
MDAFW level control valves is not
functional.
Basis for proposed no significant
hazards consideration determination:
For the proposed changes related to
TSTF–245, Revision 1, TSTF–340,
Revision 3, and new TS 3.7.5 Condition
B, 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
requirements in Technical Specification (TS)
3.7.5, ‘‘Auxiliary Feedwater (AFW) System,’’
to clarify the OPERABILITY of an AFW train
during alternate alignments, to provide
added flexibility in MODE 3 to repair and
test the turbine driven AFW pump following
a refueling outage, and to clarify the
OPERABILITY of the turbine driven AFW
train with one steam supply inoperable. The
AFW System is not an initiator of any design
basis accident or event, and therefore the
proposed change does not increase the
PO 00000
Frm 00100
Fmt 4703
Sfmt 4703
77569
probability of any accident previously
evaluated. The AFW System is used to
respond to accidents previously evaluated.
The proposed change affects only the actions
taken when portions of the AFW System are
unavailable and does not affect the design of
the AFW System. The change to TS 3.7.5
adding actions for inoperable automatic
control of level control valves does not
change any of the assumptions in accidents
previously evaluated and would not have an
impact on accident consequences. No
physical changes are made to the plant. The
proposed change does not significantly
change how the plant would mitigate an
accident previously evaluated.
Therefore, the proposed change does not
represent 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 does not result in a
change in the manner in which the AFW
System provides plant protection. The AFW
System will continue to supply water to the
steam generators to remove decay heat and
other residual heat by delivering at least the
minimum required flow rate to the steam
generators. There are no design changes
associated with the proposed changes. The
changes to the Conditions and Required
Actions do not change any existing accident
scenarios, nor create any new or different
accident scenarios.
The change does not involve a physical
alteration of the plant (i.e., no new or
different type of equipment will be installed).
The change does not alter assumptions made
in the safety analysis. The proposed change
is consistent with the safety analysis
assumptions and current plant operating
practice. Manual control of AFW level
control valves is not an accident initiator.
Therefore, it is concluded that 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 a margin of safety?
Response: No.
The proposed change does 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 this
change. The proposed change will not result
in plant operation in a configuration outside
the design basis.
Therefore, it is concluded that the
proposed change does not involve a
significant reduction in a margin of safety.
For the proposed changes related to
TSTF–412, Revision 3, in its application
dated June 1, 2011, the licensee has
affirmed the applicability of the model
no significant hazards consideration
published in the Federal Register as
part of the CLIIP (72 FR 39093; July 17,

hazards consideration, from the model
application, is presented below:
1. Does the proposed change involve a
significant increase in the probability or
consequences of any accident previously
evaluated?
Response: No.
The Auxiliary/Emergency Feedwater
(AFW/EFW) System is not an initiator of any
design basis accident or event, and therefore
the proposed changes do not increase the
probability of any accident previously
evaluated. The proposed changes to address
the condition of one or two motor driven
AFW/EFW trains inoperable and the turbine
driven AFW/EFW train inoperable due to one
steam supply inoperable do not change the
response of the plant to any accidents.
The proposed changes do 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 do not adversely affect
the ability of structures, systems, and
components (SSCs) to perform their intended
safety 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 any accident previously
evaluated. Further, the proposed changes do
not increase the types and amounts of
radioactive effluent that may be released
offsite, nor significantly increase individual
or cumulative occupational/public radiation
exposures.
Therefore, the changes do not involve a
significant increase in the probability or
consequences of any 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 changes do not result in a
change in the manner in which the AFW/
EFW System provides plant protection. The
AFW/EFW System will continue to supply
water to the steam generators to remove
decay heat and other residual heat by
delivering at least the minimum required
flow rate to the steam generators. There are
no design changes associated with the
proposed changes. The changes to the
Conditions and Required Actions 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 impose any new or different
requirements or eliminate any existing
requirements.
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.

Therefore, the changes do not create the

3. Does the proposed change 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 impacted by these
changes. The proposed changes will not
result in plant operation in a configuration
outside the design basis.
Therefore, it is concluded that the

For the proposed changes related to
TSTF–439, Revision 2, 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 changes eliminate certain
Completion Times from the Technical
Specifications. Completion Times are not an
initiator to any accident previously
evaluated. As a result, the probability of an
accident previously evaluated is not affected.
The consequences of an accident during the
revised Completion Time are no different
than the consequences of the same accident
during the existing Completion Times. As a
result, the consequences of an accident
previously evaluated are not affected by this
change. The proposed changes do not alter or
prevent the ability of structures, systems, and
components 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 the safety analysis
assumptions and resultant consequences.
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 accident
from any accident previously evaluated?
Response: No.
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. The changes do not alter any
assumptions made in the safety analysis.
Therefore, the proposed change does not

accident from any accident previously
evaluated.
3. Does the proposed change involve a
significant reduction in a margin of safety?
Response: No.
The proposed change to delete the second
Completion Time does 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 this
change. The proposed changes will not result
in plant operation in a configuration outside
of the design basis.
Therefore, the proposed change does not
involve a significant reduction in a margin of
safety.

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
with changes in brackets:
1. Does the proposed change involve a
significant increase in the probability or
consequences of an accident that has

Response: No.
The amendment request is to remove five

may be excluded from LLRT Type C testing
if they are not a potential containment
atmosphere leakage path. Based on the
design and operation of the Safety Injection
System, the valves do not constitute a
containment atmospheric leakage path as
covered in the Safety Evaluation. Since the
valves are not a leakage path, there is no
impact on the consequence of an accident.
Moreover, the valves are not a part of the
Reactor Coolant Pressure Boundary and are
normally closed during plant operation, thus
they do not affect the probability of an
accident in any way. [The change does not
affect plant equipment or operating practices
and therefore does not significantly increase
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 of malfunction that has not
previously been evaluated?
Response: No.
The system design and operation are not
changing. This test [* * *] [change] does not
change the way the valves are used as a part
of the Safety Injection System. A detailed
Failure Modes and Effects Analysis were
completed to confirm the system operation
would meet the containment isolation design
function. [The change does not add new or
change existing plant equipment or affect the
operating practices of the facility. Therefore,
the change does not create the possibility of
a new or different kind of accident from any
accident previously evaluated.]
3. Does the proposed change involve a
significant reduction in a margin of safety?
Response: No.
The test [* * *] [change] is within existing
regulatory requirements. The application of a
closed loop outside of containment is
appropriate and consistent with regulatory
positions. The closed loop is applied to cold
leg recirculation alignment of less than 8
hours when a run failure of a charging pump
or RHR [residual heat removal] pump occurs.
The probability of an HHSI\Charging Pump
failure to run is 7.025E–06 per hour and for
a LHSI [low-head safety injection]\RHR
Pump is 7.689E–06 per hour. With
containment integrity maintained within the
allowable regulatory framework, there is no
reduction in the margin of safety. [The
change does not affect plant equipment or
operating practices and therefore does not
involve a significant reduction in 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

Carolina
Date of amendment request: October
12, 2011.
Description of amendment request:
The amendment request proposes
changes to allow for a one time
extension to the 10-year frequency of
the VCSNS containment leakage rate
test (e.g., integrated leak rate test (ILRT)
or ‘‘Type A test’’) required by Technical
Specification (TS) 6.8.4(g). The
proposed change would permit the
existing ILRT frequency to be extended
from 10 years to approximately 10.9
years.
Basis for proposed no significant
hazards consideration determination:
As required by 10 CFR 50.91(a), the
licensee has provided its analysis of the
issue of no significant hazards
consideration, which is presented below
with changes in brackets.
1. Does the proposed change involve a
significant increase in the probability or
consequences of an accident that has
previously been evaluated?
Response: No.
The proposed [* * *] [change] involves a
one-time extension to the current interval for
Type A containment testing. The current test
interval of 120 months (10 years) would be
extended on a one-time basis to no longer
than approximately 130 months from the last
Type A test. The proposed extension does
not involve a physical change to the plant or
a change in the manner in which the plant
is operated or controlled. The containment is
designed to provide an essentially leak tight
barrier against the uncontrolled release of
radioactivity to the environment for
postulated accidents. As such, the reactor
containment itself and the testing
requirements invoked to periodically
demonstrate the integrity of the reactor
containment exist to ensure the plant’s
ability to mitigate the consequences of an
accident, and do not involve the prevention
or identification of any precursors of an
accident.
Therefore, this proposed extension does
not involve a significant increase in the
probability of an accident previously
evaluated nor does it create the possibility of
a new or different kind of accident.
The integrity of the reactor containment is
subject to two types of failure mechanisms
which can be categorized as (1) Activity
based and (2) time based. Activity based
failure mechanisms are defined as
degradation due to system and/or component
modifications or maintenance. Local leak rate
test requirements and administrative controls
such as configuration management and
procedural requirements for system
restoration ensure that containment integrity
is not degraded by plant modifications or
maintenance activities. The design and
PO 00000
Frm 00102

construction requirements of the
containment itself combined with the
containment inspections performed in
accordance with the [American Society of
Mechanical Engineers (ASME), Section Xl,
Boiler and Pressure Vessel Code,] the
Maintenance Rule, and Licensing
commitments serve to provide a high degree
of assurance that the containment will not
degrade in a manner that is detectable only
by a Type A test. Based on the above, the
proposed extension does not involve a
significant increase in the consequences of an
accident previously evaluated.
2. Does the proposed change create the
possibility of a new or different kind of
accident from any accident previously
evaluated?
Response: No.
The proposed revision to the TS involves
a one-time extension to the current interval
for Type A containment testing. The reactor
containment and the testing requirements
invoked to periodically demonstrate the
integrity of the reactor containment exist to
ensure the plant’s ability to mitigate the
consequences of an accident and do not
involve the prevention or identification of
any precursors of an accident. The proposed
TS change does not involve a physical
change to the plant or the manner in which
the plant is operated or controlled.
Therefore, the proposed TS change does
not create the possibility of a new or different
kind of accident from any accident
previously evaluated.
3. Does the proposed change involve a
significant reduction in a margin of safety?
Response: No.
The proposed change to the TS involves a
one-time extension to the current interval for
Type A containment testing. The proposed
TS change does not involve a physical
change to the plant or a change in the manner
in which the plant is operated or controlled.
The specific requirements and conditions of
the Primary Containment Leak Rate Testing
Program, as defined in the TS, exist to ensure
that the degree of reactor containment
structural integrity and leak-tightness that is
considered in the plant safety analysis is
maintained. The overall containment leak
rate limit specified by TS is maintained. The
proposed change involves only the extension
of the interval between Type A containment
leak rate tests. The proposed surveillance
interval extension is bounded by the 15
month extension currently authorized within
[Nuclear Energy Institute] NEI 94–01,
Revision 0. Type B and C containment leak
rate tests will continue to be performed at the
frequency currently required by TS. Industry
experience supports the conclusion that Type
B and C testing detects a large percentage of
containment leakage paths and that the
percentage of containment leakage paths that
are detected only by Type A testing is small.
The containment inspections performed in
accordance with ASME, Section Xl and the
Maintenance Rule serve to provide a high
degree of assurance that the containment will
not degrade in a manner that is detectable
only by Type A testing. The combination of
these factors ensures that the margin of safety
that is in plant safety analysis is maintained.
The design, operation, testing methods and
E:\FR\FM\13DEN1.SGM

acceptance criteria for Type A, B, and C
containment leakage tests specified in
applicable codes and standards will continue
to be met, with the acceptance of this
proposed change, since these are not affected
by changes to the Type A test interval.
Therefore, the proposed TS change does
not involve a significant reduction in a
margin of safety.
The NRC staff has reviewed the
licensee’s analysis and, based on this
review, it appears that the three
standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff

will not reduce the margin of safety. By
extending the Technical Specification
applicability to the movement of nonirradiated fuel assemblies, the current margin
of safety is maintained.
Consequently, there is no significant

possibility of a new or different kind of
accident from any accident previously
evaluated?
Response: No.
The updated fuel assembly drop analysis
demonstrates that impacted fuel assemblies
may be damaged as the result of a dropped
fuel assembly. The existing SONGS
Technical Specifications regarding
movement of fuel assemblies are not
applicable for movement of non-irradiated
fuel assemblies. A drop of a non-irradiated
fuel assembly that has radiological
consequences could occur during periods
when equipment that would be required to
mitigate those consequences is not required
to be OPERABLE in accordance with the
existing Technical Specifications.
The proposed change to the Technical
Specifications applicability language
regarding the movement of fuel assemblies in
(SONGS) Units 2 and 3 to include the
movement of both irradiated and nonirradiated fuel assemblies. The proposed
applicability is more comprehensive than the
current applicability.
Expanding the applicability of the relevant
Technical Specifications is necessary to
account for updated fuel drop analyses
which demonstrate that impacted spent fuel
assemblies may be damaged. Consequently,
movement of nonirradiated fuel assemblies
could result in a Fuel Handling Accident that
has radiological consequences. Changing the
applicability of the relevant Technical
Specifications does not affect the probability
of a Fuel Handling Accident. The expanded
applicability provides assurance that
equipment designed to mitigate a Fuel
Handling Accident is capable of performing
its specified safety function.
The dose consequences due to failure of
two assemblies remain within the Regulatory
Guide 1.183 and 10 CFR 50.67 acceptance
criteria limits. The Exclusion Area Boundary
(EAB), Low Population Zone (LPZ) and
Control Room dose results and associated

The NRC staff has reviewed the

proposes to determine that the
amendment requests involve no

Description of amendment request:
The proposed change would add
Surveillance Requirement (SR) 3.3.1.14
to FNP TS Table 3.3.1–1, ‘‘Reactor Trip
System [RTS] Instrumentation,’’
Function 3, ‘‘Power Range Neutron Flux
High Positive Rate’’ to the Technical
Specifications. SR 3.3.1.14 requires
verification that the RTS Response Time
is within limits every 18 months on a
Staggered Test Basis. Function 3 is the
Power Range Neutron Flux High
Positive Rate Trip (PFRT) 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 to Farley Nuclear
Plant (FNP) Technical Specification (TS)
3.3.1, ‘‘Reactor Trip System (RTS)
Instrumentation,’’ Table 3.3.1–1, ‘‘Reactor
Trip System Instrumentation,’’ does not
significantly increase the probability or
consequences of an accident previously
evaluated in the Update[d] Final Safety
Analysis Report (UFSAR). The overall
protection system performance will remain
within the bounds of the accident analysis
since there are no hardware changes. The
design of the Reactor Trip System (RTS)
instrumentation, specifically the power range
neutron flux high positive rate trip (PFRT)
function, will be unaffected. The reactor
protection system will continue to function
in a manner consistent with the plant design
basis. All design, material, and construction
standards, that were applicable prior to the
request, are maintained.
The proposed change imposes additional
surveillance requirements to assure safety
related structures, systems, and components
(SSCs) are verified to be consistent with the
safety analysis and licensing basis. In this
specific case, a response time verification
requirement will be added to the PFRT
function.
The proposed changes will not modify any
system interface. The proposed changes will
not affect the probability of any event
initiators. There will be no degradation in the
performance of, or an increase in the number
of challenges imposed on, safety-related
equipment assumed to function during an
accident situation. There will be no change
to normal plant operating parameters or
accident mitigation performance. The
proposed change will not alter any
assumptions nor change any mitigation
actions in the radiological consequences
evaluations in the UFSAR.
The proposed change does 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 nor
VerDate Mar<15>2010
16:25 Dec 12, 2011
Jkt 226001
prevent the ability of SSCs from performing
their intended function to mitigate the
consequences of an initiating event within
the assumed acceptance limits. The proposed
change is consistent with the safety analyses
assumptions and resultant consequences.
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
any safety related plant system performs its
safety function. This change will not affect
the normal method of plant operation nor
change any operating parameters. No
performance requirements will be affected;
however, the proposed change does impose
additional surveillance requirements. The
additional surveillance requirements are
consistent with assumptions made in the
safety analyses and licensing basis.
No new accident scenarios, transient
precursors, failure mechanisms, or limiting
single failures are introduced as a result of
this change. There will be no adverse effect
or challenges imposed on any safety-related
system as a result of this change.
Therefore, the proposed change does not
create the possibility of a new or different
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 does not affect the
acceptance criteria for any analyzed event
nor is there a change to any Safety Limits.
There will be no effect on the manner in
which Safety Limits or Limiting Conditions
of Operations are determined nor will there
be any effect on those plant systems
necessary to assure the accomplishment of
protection functions.
The safety analyses limits assumed in the
accident analysis are unchanged. The
imposition of additional surveillance
requirements increases the margin of safety
by assuring that the affected safety analyses
assumptions on equipment response time are
verified on a periodic frequency.
Therefore, the proposed change does not
involve a significant reduction in the margin
of safety.
The NRC staff has reviewed the
licensee’s analysis and, based on this
review, it appears that the three
standards of 10 CFR 50.92(c) are
satisfied. Therefore the NRC staff
proposes to determine that the
amendment request involves no
significant hazards consideration.

Notice of Consideration of Issuance of Amendments to Facility Operating
Licenses, Proposed No Significant Hazards Consideration Determination
and Opportunity for a Hearing
The Commission has made a proposed determination that the following
amendment requests involve no significant hazards consideration. Under
the Commission's regulations in Title 10 of the Code of Federal
Regulations (10 CFR) 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
[[Page 77566]]
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.
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 NRC's PDR, located at One White Flint North, Room O1-F21, 11555
Rockville Pike (first floor), Rockville, Maryland 20874. NRC
regulations are accessible electronically from the NRC Library on the
NRC Web site at https://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 NRC adjudicatory proceedings, including a
request for hearing, a petition for leave to intervene, any motion or
other document filed in the proceeding prior to the submission of a
request for hearing or petition to intervene, and documents filed by
interested governmental entities participating under 10 CFR 2.315(c),
must be filed in accordance with the NRC E-Filing rule (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 hearing.docket@nrc.gov, 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 https://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

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, with NRC edits in brackets:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
No physical changes to the facility will occur as a result of
this proposed amendment. The proposed changes will not alter the
physical design or operational procedures associated with any plant
structure, system, or component. The proposed changes are
administrative in nature and have no affect on plant operation.
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.
The proposed changes are administrative in nature. The proposed
changes do not alter the physical design, safety limits, or safety
analysis assumptions associated with the operation of the plant.
Accordingly, the changes do not introduce any new accident
initiators, nor do they reduce or adversely affect the capabilities
of any plant structure, system, or component to perform their safety
function.
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 change involve a significant reduction in a
margin of safety?
Response: No.
The proposed changes [maintain compliance with the requirements
contained in 10 CFR 50.36, ``Technical specifications.''] The
proposed changes are administrative in nature. The proposed changes
do not alter the physical design, safety limits, or safety analysis
assumptions associated with the operation of the plant.
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, with the NRC edits above, it
[[Page 77568]]
appears that the three standards of 10 CFR 50.92(c) are satisfied.
Therefore, the NRC staff proposes to determine that the amendment
request involves no significant hazards consideration.

Date of amendment request: August 11, 2011.
Description of amendment request: The proposed amendments would
make changes to the diesel fuel oil license bases and amend technical
specifications (TS) 3.7.8, ``Cooling Water (CL) System'' and 3.8.3,
``Diesel Fuel Oil.'' The proposed TS changes would revise current
requirements to reflect the addition of the license bases, resolve non-
conservative emergency diesel generator fuel oil supply volumes,
incorporate portions of Technical Specification Task Force Traveler
501, ``Relocate Stored Fuel Oil and Lube Oil Volume Values to Licensee
Control,'' and provide administrative changes to the TS.
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.
This license amendment request proposes addition of a diesel
fuel oil supply license basis and revision of the associated
Technical Specifications to require an adequate emergency diesel
generator and diesel driven cooling water pump fuel oil supply for
mitigation of a design basis accident with a loss of offsite power.
This license amendment request also proposes to: adopt provisions of
Technical Specifications Task Force (TSTF) industry traveler 501
(TSTF-501) to specify diesel fuel oil supply requirements as
required days for the supply and relocate the corresponding volume
to the Technical Specification Bases; and, make minor wording
changes to improve conformance to the content guidance of NUREG-
1431, ``Standard Technical Specifications, Westinghouse Plants.''
The emergency diesel generators, diesel driven cooling water
pumps and their supporting diesel fuel oil storage systems are not
accident initiators and therefore the proposed diesel fuel oil
supply license basis addition and proposed Technical Specification
changes do not involve an increase in the probability of an
accident.
The proposed change to the emergency diesel generator fuel oil
supply license basis and the associated Technical Specification
changes will assure that the emergency diesel generator's diesel
driven cooling water pumps perform their required design basis
accident mitigation safety function with a loss of offsite power.
Since the emergency diesel generators will provide required
electrical power as assumed in the accident analyses and the cooling
water diesel will provide cooling water as assumed in the accident
analyses, the results of the previous accident analyses are not
changed and the license basis changes proposed in this license
amendment request do not involve a significant increase in the
consequences of an accident.
Specification of the diesel fuel oil supply requirements as
required days supply in accordance with TSTF-501 continues to assure
an adequate quantity of diesel fuel oil is required to be stored;
the emergency diesel generators and diesel driven cooling water
pumps will have sufficient diesel fuel oil to mitigate a design
basis accident with a loss of offsite power, as assumed in the
accident analyses, until the fuel supply can be replenished; and
therefore, this change does not involve a significant increase in
the consequences of an accident.
The proposed minor Technical Specification wording changes to
improve alignment with the content guidance of NUREG-1431 are
administrative and thus do not involve an increase in the
consequences of an accident.
Therefore, 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.
This license amendment request proposes addition of a diesel
fuel oil supply license basis and revision of the associated
Technical Specifications to require an adequate emergency diesel
generator and diesel driven cooling water pump fuel oil supply for
mitigation of a design basis accident with a loss of offsite power.
This license amendment request also proposes to: adopt provisions of
Technical Specifications Task Force (TSTF) industry traveler 501
(TSTF-501) to specify diesel fuel oil supply requirements as
required days for the supply and relocate the corresponding volume
to the Technical Specification Bases; and, make minor wording
changes to improve conformance to the content guidance of NUREG-
1431, ``Standard Technical Specifications, Westinghouse Plants.''
The proposed diesel fuel oil supply license basis change and the
associated Technical Specification changes assure that each
emergency diesel generator and diesel driven cooling water pump has
an adequate supply of diesel fuel oil, assuming an active single
failure, to mitigate a design basis accident with a loss of offsite
power until the fuel oil supply can be replenished. The proposed
license basis change and associated Technical Specification changes
do not create new failure modes or mechanisms and no new accident
precursors are generated. The proposed specification of the diesel
fuel oil supply requirements as required days supply in accordance
with TSTF-501 does not create new failure modes or mechanisms and
does not generate new accident[s]. These proposed changes do not
challenge the performance or integrity of any safety-related system.
Surveillance requirements for the emergency diesel generator and
diesel driven cooling water pump fuel oil supplies will continue to
demonstrate that the Limiting Conditions for Operation are met and
the emergency diesel generators and diesel driven cooling water
pumps have adequate supplies of diesel fuel oil to perform their
safety functions.
The proposed minor Technical Specification wording changes to
improve alignment with the content guidance of NUREG-1431 are
administrative and thus do not create the possibility of a new or
different kind of accident.
Therefore, the proposed changes do 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.
This license amendment request proposes addition of a diesel
fuel oil supply license basis and revision of the associated
Technical Specifications to require an adequate emergency diesel
generator and diesel driven cooling water pump fuel oil supply for
mitigation of a design basis accident with a loss of offsite power.
This license amendment request also proposes to: adopt provisions of
Technical Specifications Task Force (TSTF) industry traveler 501
(TSTF-501) to specify diesel fuel oil supply requirements as
required days for the supply and relocate the corresponding volume
to the Technical Specification Bases; and, make minor wording
changes to improve conformance to the content guidance of NUREG-
1431, ``Standard Technical Specifications, Westinghouse Plants.''
The proposed diesel fuel oil supply licensing basis addition and
the associated Technical Specification changes involve the addition
of a new requirement to assure that each emergency diesel generator
and diesel driven cooling water pump has an adequate supply of
diesel fuel oil, assuming an active single failure, to mitigate a
design basis accident with a loss of offsite power until the fuel
oil supply can be replenished. The current license basis for
mitigation of an external flood without a single failure will be
maintained. Therefore, margins of safety are increased and thus no
margin of safety is reduced due to these changes.
Specification of the diesel fuel oil supply requirements as
required days supply in accordance with TSTF-501 continues to assure
an adequate quantity of diesel fuel oil is required to be stored and
thus does not reduce a margin of safety.
[[Page 77569]]
The proposed minor Technical Specification wording changes to
improve alignment with the content guidance of NUREG-1431 are
administrative and thus do not involve a significant reduction in a
margin of safety.
The proposed Technical Specification changes do not adversely
affect the availability, operability, or performance of safety-
related systems and components: the emergency diesel generators
[and] diesel driven cooling water pumps will continue to perform
their safety functions. The ability of operable structures, systems,
and components to perform their designated safety functions are
unaffected by these proposed changes. The operability requirements
of the proposed Technical Specifications are consistent with the
initial condition assumptions of the safety analyses, and the
Surveillance requirements for the emergency diesel generator and
diesel driven cooling water pump fuel oil supplies will assure that
the Limiting Conditions for Operation are met and the emergency
diesel generator's diesel driven cooling water pumps have adequate
supplies of diesel fuel oil to perform their safety functions.
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 requests involve no significant hazards consideration.

Pacific Gas and Electric Company, Docket Nos. 50-275 and 50-323, Diablo
Canyon Nuclear Power Plant, Unit 1 and 2, San Luis Obispo County,
California
Date of amendment request: June 1, 2011.
Description of amendment request: The proposed amendment would
revise Technical Specification (TS) 3.7.5, ``Auxiliary Feedwater (AFW)
System,'' TS 3.6.6, ``Containment Spray and Cooling Systems,'' TS
3.8.1, ``AC [Alternating Current] Sources--Operating,'' TS 3.8.9,
``Distribution Systems--Operating,'' and TS 1.3, ``Completion Times,''
Example 1.3-3. These changes are consistent with Technical
Specification Task Force (TSTF) Change Travelers TSTF-245, Revision 1,
``AFW Train Operable when in Service,'' TSTF-340, Revision 3, ``Allow 7
day Completion Time for a Turbine-driven AFW Pump Inoperable,'' TSTF-
412, Revision 3, ``Provide Actions for One Steam Supply to Turbine
Driven AFW/EFW [Emergency Feedwater] Pump Inoperable,'' and TSTF-439,
Revision 2, ``Eliminate Second Completion Times Limiting Time From
Discovery of Failure to Meet an LCO [Limiting Condition for
Operation].''
Specifically, the changes consistent with TSTF-245, Revision 1, and
TSTF-340, Revision 3, would revise TS 3.7.5 to clarify the operability
of an AFW train during alternate alignments and provide added
flexibility in Mode 3 to repair and test the turbine-driven AFW (TDAFW)
pump following a refueling outage. The changes consistent with TSTF-
412, Revision 3, would revise TS 3.7.5 to establish conditions,
required actions, and completion times for the condition where one
steam supply to the TDAFW is inoperable concurrent with an inoperable
motor-driven AFW (MDAFW) train. The TSTF-412, Revision 3, Notice of
Availability was published in the Federal Register on July 17, 2007 (72
FR 39089), using the consolidated line item improvement process
(CLIIP). The changes consistent with TSTF-439, Revision 2, would remove
second completion times from TS Example 1.3-3; TS 3.6.6 Required
Actions A.1, A.2, and C.1; TS 3.7.5 Required Actions A.1 and B.1; TS
3.8.1 Required Actions A.2 and B.4; and TS 3.8.9 Required Actions A.1,
B.1, and C.1. In addition, the amendment would add a new Condition B,
required actions, and completion times to TS 3.7.5 to provide specific
actions to be taken when automatic control of the MDAFW level control
valves is not functional.
Basis for proposed no significant hazards consideration
determination: For the proposed changes related to TSTF-245, Revision
1, TSTF-340, Revision 3, and new TS 3.7.5 Condition B, 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 requirements in Technical
Specification (TS) 3.7.5, ``Auxiliary Feedwater (AFW) System,'' to
clarify the OPERABILITY of an AFW train during alternate alignments,
to provide added flexibility in MODE 3 to repair and test the
turbine driven AFW pump following a refueling outage, and to clarify
the OPERABILITY of the turbine driven AFW train with one steam
supply inoperable. The AFW System is not an initiator of any design
basis accident or event, and therefore the proposed change does not
increase the probability of any accident previously evaluated. The
AFW System is used to respond to accidents previously evaluated. The
proposed change affects only the actions taken when portions of the
AFW System are unavailable and does not affect the design of the AFW
System. The change to TS 3.7.5 adding actions for inoperable
automatic control of level control valves does not change any of the
assumptions in accidents previously evaluated and would not have an
impact on accident consequences. No physical changes are made to the
plant. The proposed change does not significantly change how the
plant would mitigate an accident previously evaluated.
Therefore, the proposed change does not represent 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 does not result in a change in the manner in
which the AFW System provides plant protection. The AFW System will
continue to supply water to the steam generators to remove decay
heat and other residual heat by delivering at least the minimum
required flow rate to the steam generators. There are no design
changes associated with the proposed changes. The changes to the
Conditions and Required Actions do not change any existing accident
scenarios, nor create any new or different accident scenarios.
The change does not involve a physical alteration of the plant
(i.e., no new or different type of equipment will be installed). The
change does not alter assumptions made in the safety analysis. The
proposed change is consistent with the safety analysis assumptions
and current plant operating practice. Manual control of AFW level
control valves is not an accident initiator.
Therefore, it is concluded that 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 a
margin of safety?
Response: No.
The proposed change does 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 this change. The proposed change will not result
in plant operation in a configuration outside the design basis.
Therefore, it is concluded that the proposed change does not
involve a significant reduction in a margin of safety.
For the proposed changes related to TSTF-412, Revision 3, in its
application dated June 1, 2011, the licensee has affirmed the
applicability of the model no significant hazards consideration
published in the Federal Register as part of the CLIIP (72 FR 39093;
July 17, 2007). As required by 10 CFR 50.91(a), an analysis of the
issue of no significant
[[Page 77570]]
hazards consideration, from the model application, is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of any accident previously
evaluated?
Response: No.
The Auxiliary/Emergency Feedwater (AFW/EFW) System is not an
initiator of any design basis accident or event, and therefore the
proposed changes do not increase the probability of any accident
previously evaluated. The proposed changes to address the condition
of one or two motor driven AFW/EFW trains inoperable and the turbine
driven AFW/EFW train inoperable due to one steam supply inoperable
do not change the response of the plant to any accidents.
The proposed changes do 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 do not adversely
affect the ability of structures, systems, and components (SSCs) to
perform their intended safety 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 any accident previously evaluated.
Further, the proposed changes do not increase the types and amounts
of radioactive effluent that may be released offsite, nor
significantly increase individual or cumulative occupational/public
radiation exposures.
Therefore, the changes do not involve a significant increase in
the probability or consequences of any 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 changes do not result in a change in the manner in
which the AFW/EFW System provides plant protection. The AFW/EFW
System will continue to supply water to the steam generators to
remove decay heat and other residual heat by delivering at least the
minimum required flow rate to the steam generators. There are no
design changes associated with the proposed changes. The changes to
the Conditions and Required Actions 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 impose any new or different requirements or
eliminate any existing requirements.
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.
Therefore, the changes do not create the possibility of a new or
different kind of accident from any accident previously evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The proposed 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. The proposed changes will not
result in plant operation in a configuration outside the design
basis.
Therefore, it is concluded that the proposed change does not
involve a significant reduction in a margin of safety.
For the proposed changes related to TSTF-439, Revision 2, 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 changes eliminate certain Completion Times from the
Technical Specifications. Completion Times are not an initiator to
any accident previously evaluated. As a result, the probability of
an accident previously evaluated is not affected. The consequences
of an accident during the revised Completion Time are no different
than the consequences of the same accident during the existing
Completion Times. As a result, the consequences of an accident
previously evaluated are not affected by this change. The proposed
changes do not alter or prevent the ability of structures, systems,
and components 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 the safety analysis assumptions and resultant
consequences.
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 accident from any accident previously evaluated?
Response: No.
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. The changes
do not alter any assumptions made in the safety analysis.
Therefore, the proposed change does 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.
The proposed change to delete the second Completion Time does
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 this change.
The proposed changes will not result in plant operation in a
configuration outside of the design basis.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
Based on the above, the NRC staff has reviewed the licensee's
analyses 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.

South Carolina Electric and Gas Company, South Carolina Public Service
Authority, Docket No. 50-395, Virgil C. Summer Nuclear Station (VCSNS),
Unit 1, Fairfield County, South Carolina
Date of amendment request: October 12, 2011.
Description of amendment request: The amendment requests
authorization to update the facility's Final Safety Analysis Report to
exempt five Unit 1 high-head safety injection system (HHSI) containment
isolation valves (CIVs) from the VCSNS, Unit No. 1 Local Leak Rate
Testing (LLRT) Program requirements.
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 with changes in brackets:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident that has previously
been evaluated?
Response: No.
The amendment request is to remove five Containment Isolation
Valves (XVG08801A, XVG08801B, XVG08884, XVG08885, and XVG08886) from
the Local Leak Rate Test (LLRT) program. These valves were
originally included in the LLRT under 10 CFR [part] 50, Appendix J,
in what is now Option A. VCSNS has been approved for 10 CFR [Part]
50, Appendix J, Option B under License Amendment No. 135. Under
Option B, valves
[[Page 77571]]
may be excluded from LLRT Type C testing if they are not a potential
containment atmosphere leakage path. Based on the design and
operation of the Safety Injection System, the valves do not
constitute a containment atmospheric leakage path as covered in the
Safety Evaluation. Since the valves are not a leakage path, there is
no impact on the consequence of an accident. Moreover, the valves
are not a part of the Reactor Coolant Pressure Boundary and are
normally closed during plant operation, thus they do not affect the
probability of an accident in any way. [The change does not affect
plant equipment or operating practices and therefore does not
significantly increase 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 of malfunction that has not previously
been evaluated?
Response: No.
The system design and operation are not changing. This test [* *
*] [change] does not change the way the valves are used as a part of
the Safety Injection System. A detailed Failure Modes and Effects
Analysis were completed to confirm the system operation would meet
the containment isolation design function. [The change does not add
new or change existing plant equipment or affect the operating
practices of the facility. Therefore, the change does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.]
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The test [* * *] [change] is within existing regulatory
requirements. The application of a closed loop outside of
containment is appropriate and consistent with regulatory positions.
The closed loop is applied to cold leg recirculation alignment of
less than 8 hours when a run failure of a charging pump or RHR
[residual heat removal] pump occurs. The probability of an
HHSI\Charging Pump failure to run is 7.025E-06 per hour and for a
LHSI [low-head safety injection]\RHR Pump is 7.689E-06 per hour.
With containment integrity maintained within the allowable
regulatory framework, there is no reduction in the margin of safety.
[The change does not affect plant equipment or operating practices

Authority, Docket No. 50-395, Virgil C. Summer Nuclear Station, Unit 1
(VCSNS), Fairfield County, South Carolina
Date of amendment request: October 12, 2011.
Description of amendment request: The amendment request proposes
changes to allow for a one time extension to the 10-year frequency of
the VCSNS containment leakage rate test (e.g., integrated leak rate
test (ILRT) or ``Type A test'') required by Technical Specification
(TS) 6.8.4(g). The proposed change would permit the existing ILRT
frequency to be extended from 10 years to approximately 10.9 years.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below with changes in brackets.
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident that has previously
been evaluated?
Response: No.
The proposed [* * *] [change] involves a one-time extension to
the current interval for Type A containment testing. The current
test interval of 120 months (10 years) would be extended on a one-
time basis to no longer than approximately 130 months from the last
Type A test. The proposed extension does not involve a physical
change to the plant or a change in the manner in which the plant is
operated or controlled. The containment is designed to provide an
essentially leak tight barrier against the uncontrolled release of
radioactivity to the environment for postulated accidents. As such,
the reactor containment itself and the testing requirements invoked
to periodically demonstrate the integrity of the reactor containment
exist to ensure the plant's ability to mitigate the consequences of
an accident, and do not involve the prevention or identification of
any precursors of an accident.
Therefore, this proposed extension does not involve a
significant increase in the probability of an accident previously
evaluated nor does it create the possibility of a new or different
kind of accident.
The integrity of the reactor containment is subject to two types
of failure mechanisms which can be categorized as (1) Activity based
and (2) time based. Activity based failure mechanisms are defined as
degradation due to system and/or component modifications or
maintenance. Local leak rate test requirements and administrative
controls such as configuration management and procedural
requirements for system restoration ensure that containment
integrity is not degraded by plant modifications or maintenance
activities. The design and construction requirements of the
containment itself combined with the containment inspections
performed in accordance with the [American Society of Mechanical
Engineers (ASME), Section Xl, Boiler and Pressure Vessel Code,] the
Maintenance Rule, and Licensing commitments serve to provide a high
degree of assurance that the containment will not degrade in a
manner that is detectable only by a Type A test. Based on the above,
the proposed extension does not involve a significant increase in
the consequences of an accident previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The proposed revision to the TS involves a one-time extension to
the current interval for Type A containment testing. The reactor
containment and the testing requirements invoked to periodically
demonstrate the integrity of the reactor containment exist to ensure
the plant's ability to mitigate the consequences of an accident and
do not involve the prevention or identification of any precursors of
an accident. The proposed TS change does not involve a physical
change to the plant or the manner in which the plant is operated or
controlled.
Therefore, the proposed TS change does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The proposed change to the TS involves a one-time extension to
the current interval for Type A containment testing. The proposed TS
change does not involve a physical change to the plant or a change
in the manner in which the plant is operated or controlled. The
specific requirements and conditions of the Primary Containment Leak
Rate Testing Program, as defined in the TS, exist to ensure that the
degree of reactor containment structural integrity and leak-
tightness that is considered in the plant safety analysis is
maintained. The overall containment leak rate limit specified by TS
is maintained. The proposed change involves only the extension of
the interval between Type A containment leak rate tests. The
proposed surveillance interval extension is bounded by the 15 month
extension currently authorized within [Nuclear Energy Institute] NEI
94-01, Revision 0. Type B and C containment leak rate tests will
continue to be performed at the frequency currently required by TS.
Industry experience supports the conclusion that Type B and C
testing detects a large percentage of containment leakage paths and
that the percentage of containment leakage paths that are detected
only by Type A testing is small. The containment inspections
performed in accordance with ASME, Section Xl and the Maintenance
Rule serve to provide a high degree of assurance that the
containment will not degrade in a manner that is detectable only by
Type A testing. The combination of these factors ensures that the
margin of safety that is in plant safety analysis is maintained. The
design, operation, testing methods and
[[Page 77572]]
acceptance criteria for Type A, B, and C containment leakage tests
specified in applicable codes and standards will continue to be met,
with the acceptance of this proposed change, since these are not
affected by changes to the Type A test interval.
Therefore, the proposed TS change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Southern California Edison Company, et al., Docket Nos. 50-361 and 50-
362, San Onofre Nuclear Generating Station, Units 2 and 3, San Diego
County, California
Date of amendment request: September 2, 2011.
Description of amendment request: The amendments would revise a
number of Technical Specification (TS) requirements, to impose similar
restrictions on the movement of non-irradiated fuel assemblies to those
currently in place for movement of irradiated fuel assemblies. The
additional restrictions will limit the movement of all fuel assemblies
over irradiated fuel assemblies in containment or in the fuel storage
pool.
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 Technical Specifications
applicability wording regarding the movement of fuel assemblies in
containment and the fuel storage pool at the San Onofre Nuclear
Generating Station (SONGS) Units 2 and 3 to include the movement of
both irradiated and non-irradiated fuel assemblies. The proposed
applicability is more comprehensive than the current applicability.
Expanding the applicability of the relevant Technical
Specifications is necessary to account for updated fuel drop
analyses which demonstrate that impacted spent fuel assemblies may
be damaged. Consequently, movement of nonirradiated fuel assemblies
could result in a Fuel Handling Accident that has radiological
consequences. Changing the applicability of the relevant Technical
Specifications does not affect the probability of a Fuel Handling
Accident. The expanded applicability provides assurance that
equipment designed to mitigate a Fuel Handling Accident is capable
of performing its specified safety function.
The dose consequences due to failure of two assemblies remain
within the Regulatory Guide 1.183 and 10 CFR 50.67 acceptance
criteria limits. The Exclusion Area Boundary (EAB), Low Population
Zone (LPZ) and Control Room dose results and associated limits are

Consequently, 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 updated fuel assembly drop analysis demonstrates that
impacted fuel assemblies may be damaged as the result of a dropped
fuel assembly. The existing SONGS Technical Specifications regarding
movement of fuel assemblies are not applicable for movement of non-
irradiated fuel assemblies. A drop of a non-irradiated fuel assembly
that has radiological consequences could occur during periods when
equipment that would be required to mitigate those consequences is
not required to be OPERABLE in accordance with the existing
Technical Specifications.
The proposed change to the Technical Specifications
applicability language regarding the movement of fuel assemblies in
containment and the fuel storage pool at SONGS Units 2 and 3 ensure
that Limiting Conditions for Operation and appropriate Required
Actions for required equipment are in effect during fuel movement.
This provides assurance that any Fuel Handling Accident that may
occur will remain within the initial assumptions of accident
analyses.
Consequently, there is no possibility of a new or different kind
of accident due to the proposed change.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The proposed change will not affect protection criterion for
plant equipment and will not reduce the margin of safety. By
extending the Technical Specification applicability to the movement
of non-irradiated fuel assemblies, the current margin of safety is
maintained.
Consequently, there is no significant reduction in a margin of
safety due to the proposed change.
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 requests involve no significant hazards consideration.

County, Alabama
Date of amendment request: September 9, 2011.
[[Page 77573]]
Description of amendment request: The proposed change would add
Surveillance Requirement (SR) 3.3.1.14 to FNP TS Table 3.3.1-1,
``Reactor Trip System [RTS] Instrumentation,'' Function 3, ``Power
Range Neutron Flux High Positive Rate'' to the Technical
Specifications. SR 3.3.1.14 requires verification that the RTS Response
Time is within limits every 18 months on a Staggered Test Basis.
Function 3 is the Power Range Neutron Flux High Positive Rate Trip
(PFRT) 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 to Farley Nuclear Plant (FNP) Technical
Specification (TS) 3.3.1, ``Reactor Trip System (RTS)
Instrumentation,'' Table 3.3.1-1, ``Reactor Trip System
Instrumentation,'' does not significantly increase the probability
or consequences of an accident previously evaluated in the Update[d]
Final Safety Analysis Report (UFSAR). The overall protection system
performance will remain within the bounds of the accident analysis
since there are no hardware changes. The design of the Reactor Trip
System (RTS) instrumentation, specifically the power range neutron
flux high positive rate trip (PFRT) function, will be unaffected.
The reactor protection system will continue to function in a manner
consistent with the plant design basis. All design, material, and
construction standards, that were applicable prior to the request,
are maintained.
The proposed change imposes additional surveillance req
