Notice of Consideration of Issuance of Amendments to Facility Operating
Licenses and Combined Licenses, Proposed No Significant Hazards
Consideration Determination, and Opportunity for a Hearing
The Commission has made a proposed determination that the following
amendment requests involve no significant hazards consideration. Under
the Commission's regulations in Title 10 of the Code of Federal
Regulations (10 CFR) 50.92, this means that operation of the facility
in accordance with the proposed amendment would not (1) involve a
significant increase in the probability or consequences of an accident
previously evaluated; or (2) create the possibility of a new or
different kind of accident from any accident previously evaluated; or
(3) involve a significant reduction in a margin of safety. The basis
for this proposed determination for each amendment request is shown
below.
The Commission is seeking public comments on this proposed
determination. Any comments received within 30 days after the date of
publication of this notice will be considered in making any final
determination.
Normally, the Commission will not issue the amendment until the
expiration of 60 days after the date of publication of this notice. The
Commission may issue the license amendment before expiration of the 60-
day period provided that its final determination is that the amendment
involves no significant hazards consideration. In addition, the
Commission may issue the amendment prior to the expiration of the 30-
day comment period should circumstances change during the 30-day
comment period such that failure to act in a timely way would result,
for example in derating or shutdown of the facility. Should the
Commission take action prior to the expiration of either the comment
period or the notice period, it will publish in the Federal Register a
notice of issuance. Should the Commission make a final No Significant
Hazards Consideration Determination; any hearing will take place after
issuance. The Commission expects that the need to take this action will
occur very infrequently.
Within 60 days after the date of publication of this notice, any
person(s) whose interest may be affected by this action may file a
request for a hearing and a petition to intervene with respect to
issuance of the amendment to the subject facility operating license or
combined license. Requests for a hearing and a petition for leave to
intervene shall be filed in accordance with the Commission's ``Rules of
Practice for Domestic Licensing Proceedings'' in 10 CFR part 2.
Interested person(s) should consult a current copy of 10 CFR 2.309,
which is available at the NRC's PDR, located at One White Flint North,
Room O1-F21, 11555 Rockville Pike (first floor), Rockville, Maryland
20852. NRC regulations are accessible electronically from the NRC
Library on the NRC's Web site at http://www.nrc.gov/reading-rm/doc-collections/cfr/. If a request for a hearing or petition for leave to
intervene is filed by the above date, the Commission or a presiding
officer designated by the Commission or by the Chief Administrative
Judge of the Atomic Safety and Licensing Board Panel, will rule on the
request and/or petition; and the Secretary or the Chief Administrative
Judge of the Atomic Safety and Licensing Board will issue a notice of a
hearing or an appropriate order.
As required by 10 CFR 2.309, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following general requirements: (1) The name, address, and telephone
number of the requestor or petitioner; (2) the nature of the
requestor's/petitioner's right under the Act to be made a party to the
proceeding; (3) the nature and extent of the requestor's/petitioner's
property, financial, or other interest in the proceeding; and (4) the
possible effect of any decision or order which may be entered in the
proceeding on the requestor's/petitioner's interest. The petition must
also identify the specific contentions which the requestor/petitioner
seeks to have litigated at the proceeding.
Each contention must consist of a specific statement of the issue
of law or fact to be raised or controverted. In addition, the
requestor/petitioner shall provide a brief explanation of the bases for
the contention and a concise statement of the alleged facts or expert
opinion which support the contention and on which the requestor/
petitioner intends to rely in proving the contention at the hearing.
The requestor/petitioner must also provide references to those specific
sources and documents of which the petitioner is aware and on which the
requestor/petitioner intends to rely to establish those facts or expert
opinion. The petition must include sufficient information to show that
a genuine dispute exists with the applicant on a material issue of law
or fact. Contentions shall be limited to matters within the scope of
the amendment under consideration. The contention must be one which, if
proven, would entitle the requestor/petitioner to relief. A requestor/
petitioner who fails to satisfy these requirements with respect to at
least one contention will not be permitted to participate as a party.
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing.
If a hearing is requested, the Commission will make a final
[[Page 28628]]
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 [email protected], or by
telephone at 301-415-1677, to request (1) a digital identification (ID)
certificate, which allows the participant (or its counsel or
representative) to digitally sign documents and access the E-Submittal
server for any proceeding in which it is participating; and (2) advise
the Secretary that the participant will be submitting a request or
petition for hearing (even in instances in which the participant, or
its counsel or representative, already holds an NRC-issued digital ID
certificate). Based upon this information, the Secretary will establish
an electronic docket for the hearing in this proceeding if the
Secretary has not already established an electronic docket.
Information about applying for a digital ID certificate is
available on the NRC's public Web site at http://www.nrc.gov/site-help/e-submittals/apply-certificates.html. System requirements for accessing
the E-Submittal server are detailed in the NRC's ``Guidance for
Electronic Submission,'' which is available on the agency's public Web
site at http://www.nrc.gov/site-help/e-submittals.html. Participants
may attempt to use other software not listed on the Web site, but
should note that the NRC's E-Filing system does not support unlisted
software, and the NRC Meta System Help Desk will not be able to offer
assistance in using unlisted software.
If a participant is electronically submitting a document to the NRC
in accordance with the E-Filing rule, the participant must file the
document using the NRC's online, Web-based submission form. In order to
serve documents through the Electronic Information Exchange System,
users will be required to install a Web browser plug-in from the NRC's
Web site. Further information on the Web-based submission form,
including the installation of the Web browser plug-in, is available on
the NRC's public Web site at http://www.nrc.gov/site-help/e-submittals.html.
Once a participant has obtained a digital ID certificate and a
docket has been created, the participant can then submit a request for
hearing or petition for leave to intervene. Submissions should be in
Portable Document Format (PDF) in accordance with the NRC guidance
available on the NRC's public Web site at http://www.nrc.gov/site-help/e-submittals.html. A filing is considered complete at the time the
documents are submitted through the NRC's E-Filing system. To be
timely, an electronic filing must be submitted to the E-Filing system
no later than 11:59 p.m. Eastern Time on the due date. Upon receipt of
a transmission, the E-Filing system time-stamps the document and sends
the submitter an email notice confirming receipt of the document. The
E-Filing system also distributes an email notice that provides access
to the document to the NRC's Office of the General Counsel and any
others who have advised the Office of the Secretary that they wish to
participate in the proceeding, so that the filer need not serve the
documents on those participants separately. Therefore, applicants and
other participants (or their counsel or representative) must apply for
and receive a digital ID certificate before a hearing request/petition
to intervene is filed so that they can obtain access to the document
via the E-Filing system.
A person filing electronically using the agency's adjudicatory E-
Filing system may seek assistance by contacting the NRC Meta System
Help Desk through the ``Contact Us'' link located on the NRC Web site
at http://www.nrc.gov/site-help/e-submittals.html, by email at
[email protected], or by a toll-free call at 1-866 672-7640. The
NRC Meta System Help Desk is available between 8 a.m. and 8 p.m.,
Eastern Time, Monday through Friday, excluding government holidays.
Participants who believe that they have a good cause for not
submitting documents electronically must file an exemption request, in
accordance with 10 CFR 2.302(g), with their initial paper filing
requesting authorization to continue to submit documents in paper
format. Such filings must be submitted by: (1) First class mail
addressed to the Office of the Secretary of the Commission, U.S.
Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention:
Rulemaking and Adjudications Staff; or (2) courier, express mail, or
expedited delivery service to the Office of the Secretary, Sixteenth
Floor, One White Flint North, 11555 Rockville Pike, Rockville,
Maryland, 20852, Attention: Rulemaking and Adjudications Staff.
Participants filing a document in this manner are responsible for
serving the document on all other participants. Filing is considered
complete by first-class mail as of the time of deposit in the mail, or
by courier, express mail, or expedited delivery service upon depositing
the document with the provider of the service. A presiding officer,
having granted an exemption request from using E-Filing, may require a
participant or party to use E-Filing if the presiding officer
subsequently determines that the reason for granting the exemption from
use of E-Filing no longer exists.
Documents submitted in adjudicatory proceedings will appear in the
NRC's electronic hearing docket which is available to the public at
http://ehd1.nrc.gov/ehd/, unless excluded pursuant to an order of the
Commission, or the presiding officer. Participants are requested not to
include personal privacy information, such as social security numbers,
home addresses, or home phone numbers in their filings, unless an NRC
regulation or other law requires submission of such information. With
respect to copyrighted works, except for limited excerpts that serve
the purpose of the adjudicatory filings and would constitute a Fair Use
application, participants are requested not to include copyrighted
materials in their submission.
Petitions for leave to intervene must be filed no later than 60
days from the date of publication of this notice. Non-
[[Page 28629]]
timely filings will not be entertained absent a determination by the
presiding officer that the petition or request should be granted or the
contentions should be admitted, based on a balancing of the factors
specified in 10 CFR 2.309(c)(1)(i)-(viii).

Dominion Nuclear Connecticut, Inc., Docket No. 50-423, Millstone Power
Station, Unit 3, New London County, Connecticut
Date of amendment request: November 17, 2011.
Description of amendment request: The proposed amendment would add
Optimized ZIRLOTM as an allowable fuel rod cladding material
and add the Westinghouse topical report on Optimized ZIRLOTM
to the Millstone Power Station, Unit 3 (MPS3) Technical Specifications.
In addition, a typographical error would be corrected.
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 Technical Specifications changes are: (1) Adding
Optimized ZIRLOTM to the allowable or approved cladding
materials to be used at MPS3, and (2) correcting a typographical
error in the title of Reference 8 in Technical Specification (TS)
6.9.1.6.b. The proposed change of adding a cladding material does
not result in an increase to the probability or consequences of an
accident previously evaluated. Technical Specification 5.3.1
addresses the fuel assembly design, and currently specifies that
``Each assembly shall consist of a matrix of Zircaloy or
ZIRLO[supreg] fuel rods * * *''. The proposed change will add
Optimized ZIRLOTM to the approved fuel rod cladding
materials listed in this technical specification. In addition, a
reference to the topical report for Optimized ZIRLOTM,
WCAP-12610-P-A and CENPD-404-P-A, Addendum 1-A, will be added to the
listing of approved methods used to determine the core operating
limits for MPS3 provided in Technical Specification 6.9.1.6.b.
Westinghouse topical report WCAP-12610-P-A & CENPD-404-P-A,
Addendum 1-A, ``Optimized ZIRLOTM,'' provides the details and
results of material testing of Optimized ZIRLOTM compared
to standard ZIRLO[supreg], as well as the material properties to be
used in various models and methodologies when analyzing Optimized
ZIRLOTM. As the nuclear industry pursues longer operating
cycles with increased fuel discharge burnup and fuel duty, the
corrosion performance requirements for the nuclear fuel cladding
become more demanding. Optimized ZIRLOTM was developed to
meet these industry needs by providing a reduced corrosion rate
while maintaining the composition and physical properties, such as
mechanical strength, similar to standard ZIRLO[supreg]. In addition,
margin to the fuel rod design criterion on fuel rod internal
pressure has been impacted by increased fuel duty, use of integral
fuel burnable absorbers, and corrosion/temperature feedback effects.
Reducing the associated corrosion buildup reduces temperature
feedback effects, providing additional margin to the fuel rod
internal pressure design criterion. The fuel will continue to
satisfy the pertinent design basis operating limits, so cladding
integrity is maintained. There are no changes that will adversely
affect the ability of existing components and systems to mitigate
the consequences of any accident. Addition of Optimized
ZIRLOTM to the allowable cladding materials for MPS3
therefore does not result in a significant increase in the
probability or consequences of an accident previously evaluated.
The NRC has previously approved use of Optimized
ZIRLOTM fuel cladding material in Westinghouse fueled
reactors provided that licensees ensure compliance with the
Conditions and Limitations set forth in the NRC Safety Evaluation
for the topical report. Confirmation that these Conditions are
satisfied is performed under 10 CFR 50.59 as part of the normal core
reload process.
The change to the title of Reference 8 in Technical
Specification 6.9.1.6.b is administrative in nature and does not
alter any of the requirements of the affected TS. The proposed
change does not modify any plant equipment and does not impact any
failure modes that could lead to an accident. Additionally, the
proposed change has no effect on the consequence of any analyzed
accident since the change does not affect any equipment related to
accident mitigation.
Based on this discussion, the proposed change 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 from any accident previously evaluated?
Response: No.
The proposed Technical Specifications change adds Optimized
ZIRLOTM to the approved fuel rod cladding materials that
may be used at MPS3. Optimized ZIRLOTM was developed to
provide a reduced cladding corrosion rate while maintaining the
benefits of mechanical strength and resistance to accelerated
corrosion from potential abnormal chemistry conditions. The fuel rod
design bases are established to satisfy the general and specific
safety criteria addressed in the MPS3 Final Safety Analysis Report
(FSAR), Chapter 15 (Accident Analyses). The fuel rods are designed
to prevent excessive fuel temperatures, excessive fuel rod internal
gas pressures due to fission gas releases, and excessive cladding
stresses and strains. Westinghouse topical report WCAP-12610-P-A &
CENPD-404-P-A, Addendum 1-A, ``Optimized ZIRLOTM,''
provides the details and results of material testing of Optimized
ZIRLOTM compared to standard ZIRLO[supreg], as well as
the material properties to be used in various models and
methodologies when analyzing Optimized ZIRLOTM. The
original fuel design basis requirements have been maintained. No new
single failure mechanisms will be created, and there are no
alterations to plant equipment or procedures that would introduce
any new or unique operational modes or accident precursors.
Therefore, the proposed changes to the MPS3 TSs related to the
use of Optimized ZIRLOTM do not create the possibility of
a new or different kind of accident or malfunction from those
previously evaluated within the FSAR.
The change to the title of Reference 8 in Technical
Specification 6.9.1.6.b is administrative in nature. It does not
modify any plant equipment and there is no impact on the capability
of the existing equipment to perform their intended functions. No
system setpoints are being modified and no changes are being made to
the method in which plant operations are conducted. No new failure
modes are introduced by the proposed changes. The proposed change
does not introduce accident initiators or malfunctions that would
cause a new or different kind of accident.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any accident previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The cladding materials used for fuel rods are designed and
tested to prevent excessive fuel temperatures, excessive fuel rod
internal gas pressures due to fission .as releases, and excessive
cladding stresses and strains. Optimized ZIRLOTM was
developed to meet these needs while providing a reduced cladding
corrosion rate and maintaining the benefits of mechanical strength
and resistance to accelerated corrosion from potential abnormal
chemistry conditions. Reducing the associated corrosion buildup
reduces temperature feedback effects, providing additional margin to
the fuel rod internal pressure design criterion. Westinghouse
topical report WCAP-12610-P-A & CENPD-404-P-A, Addendum 1-A,
``Optimized ZIRLOTM'' provides the details and results of
material testing of Optimized ZIRLOTM compared to
standard ZIRLO[supreg], as
[[Page 28630]]
well as the material properties to be used in various models and
methodologies when analyzing Optimized ZIRLOTM. The NRC
has previously approved use of the Optimized ZIRLOTM fuel
cladding material as detailed in their Safety Evaluation for this
topical report. The original fuel design basis requirements have
been maintained, and evaluations will be performed under 10 CFR
50.59 for each reload cycle that incorporates Optimized
ZIRLOTM cladding to confirm that design and safety limits
are satisfied. Therefore, inclusion of Optimized ZIRLOTM
as an additional fuel rod cladding material for MPS3 does not result
in a significant reduction in margin required to preclude or reduce
the effects of an accident or malfunction previously evaluated in
the FSAR.
The change to the title of Reference 8 in Technical
Specification 6.9.1.6.b is administrative in nature. This change
does not alter any of the requirements of the affected TS. The
proposed change does not affect any of the assumptions used in the
accident analysis, nor does it affect any operability requirements
for equipment important to plant safety.
Therefore, the proposed change will not result in a significant
reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Duke Energy Carolinas, LLC, Docket Nos. 50-369 and 50-370, McGuire
Nuclear Station, Units 1 and 2, Mecklenburg County, North Carolina
Date of amendment request: March 5, 2012.
Description of amendment request: The proposed amendments would
implement a measurement uncertainty recapture power uprate at the
McGuire Nuclear Station, Units 1 and 2.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed amendment involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed amendment changes the rated thermal power from 3411
megawatts thermal (MWt) to 3469 MWt; an increase of approximately
1.7% Rated Thermal Power. Duke Energy's evaluations have shown that
all structures, systems and components (SSCs) are capable of
performing their design function at the uprated power of 3469 MWt. A
review of station accident analyses found that all acceptance
criteria are still met at the uprated power of 3469 MWt.
The radiological consequences of operation at the uprated power
conditions have been assessed. The proposed power uprate does not
affect release paths, frequency of release, or the analyzed reactor
core fission product inventory for any accidents previously
evaluated in the Final Safety Analysis Report. Analyses performed to
assess the effects of mass and energy releases remain valid. All
acceptance criteria for radiological consequences continue to be met
at the uprated power level.
As summarized in Sections IV, V, and VI of Enclosure 2, the
proposed change does not involve any change to the design or
functional requirements of the safety and support systems. That is,
the increased power level neither degrades the performance of, nor
increases the challenges to any safety systems assumed to function
in the plant safety analysis.
While power level is an input to accident analyses, it is not an
initiator of accidents. The proposed change does not affect any
accident precursors and does not introduce any accident initiators.
The proposed change does not impact the usefulness of the
Surveillance Requirements (SRs) in evaluating the operability of
required systems and components.
In addition, evaluation of the proposed TS change demonstrates
that the availability of equipment and systems required to prevent
or mitigate the radiological consequences of an accident is not
significantly affected. Since the impact on the systems is minimal,
it is concluded that the overall impact on the plant safety analysis
is negligible.
Therefore, the proposed TS changes do not significantly increase
the probability or consequences of an accident previously evaluated.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
A Failure Modes and Effects Analysis of the new system was
performed and the possible effects of failures of the new equipment
and the increased power level on the overall plant systems were
reviewed. This review found that no new or different accidents were
created by the new equipment or the uprated power levels.
No installed equipment is being operated in a different manner.
The proposed changes have no significant adverse affect on any
safety-related structures, systems or components and do not
significantly change the performance or integrity of any safety-
related system.
The proposed changes do not adversely affect any current system
interfaces or create any new interfaces that could result in an
accident or malfunction of a different kind than previously
evaluated. The uprated power does not create any new accident
initiators. Credible malfunctions are bounded by the current
accident analyses of record or recent evaluations demonstrating that
applicable criteria are still met with the proposed changes.
Therefore, this change does not create the possibility of a new
or different kind of accident from any accident previously
evaluated.
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
Response: No.
Although the proposed amendment increases the operating power
level of the plants, it retains the margin of safety because it is
only increasing power by the amount equal to the reduction in
uncertainty in the heat balance calculation. The margins of safety
associated with the power uprate are those pertaining to core
thermal power. These include fuel cladding, reactor coolant system
pressure boundary, and containment barriers. Analyses demonstrate
that the design basis continues to be met after the measurement
uncertainty recapture (MUR) power uprate. Components associated with
the reactor coolant system pressure boundary structural integrity,
including pressure-temperature limits, vessel fluence, and
pressurized thermal shock are bounded by the current analyses.
Systems will continue to operate within their design parameters and
remain capable of performing their intended safety functions.
The current McGuire safety analyses including the revised design
basis radiological accident dose calculations, bound the power
uprate.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

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:
[[Page 28631]]
First Standard
Does operation of the facility in accordance with the proposed
amendment involve a significant increase in the probability or
consequences of an accident previously evaluated?
Response: No.
The proposed single discharge header operation configuration for
NSWS operation and the associated proposed TS and Bases changes have
been evaluated to assess their impact on plant operation and to
ensure that the design basis safety functions of safety related
systems are not adversely impacted. During single discharge header
operation, the operating NSWS header will be able to discharge all
required NSWS flow from safety related components. [Probabilistic
risk assessment] PRA has demonstrated that due to the limited
proposed time in the single discharge header configuration, the
resultant plant risk remains acceptable.
The purpose of this amendment request is to ultimately
facilitate inspection and maintenance of the Unit 2 NSWS discharge
headers within the Auxiliary Building. Therefore, NRC approval of
this request will ultimately help to enhance the long-term
structural integrity of the NSWS and will help to ensure the
system's reliability for many years.
In general, the NSWS serves as an accident mitigation system and
cannot by itself initiate an accident or transient situation. The
only exception is that the NSWS piping can serve as a source of
floodwater to safety related equipment in the Auxiliary Building or
in the diesel generator buildings in the event of a leak or a break
in the system piping. The probability of such an event is not
significantly increased as a result of this proposed request. Safety
related NSWS piping is tested and inspected in accordance with all
applicable inservice testing and inservice inspection requirements.
Given the negligible influence of flooding events on the NSWS for
the submittal configuration (i.e., no dominant contribution from
floods), it is judged that the analyses assessing the influence of
these events provide an acceptable evaluation of the contribution of
the flood risk for the requested Completion Time of 14 days.
The proposed 14 day TS Required Action Completion Time has been
evaluated for risk significance and the results of this evaluation
have been found acceptable. The probabilities of occurrence of
accidents presented in the [updated final safety analysis report]
UFSAR will not increase as a result of implementation of this
change. Because the PRA analysis supporting the proposed change
yielded acceptable results, the NSWS will maintain its required
availability in response to accident situations. Since NSWS
availability is maintained, the response of the plant to accident
situations will remain acceptable and the consequences of accidents
presented in the UFSAR will not increase.
Second Standard
Does operation of the facility in accordance with the proposed
amendment create the possibility of a new or different kind of
accident from any accident previously evaluated?
Response: No.
Implementation of this amendment will not create the possibility
of a new or different kind of accident from any accident previously
evaluated. The proposed request does not affect the basic operation
of the NSWS or any of the systems that it supports. These include
the Emergency Core Cooling System, the Containment Spray System, the
Containment Valve Injection Water System, the Auxiliary Feedwater
System, the Component Cooling Water System, the Control Room Area
Ventilation System, the Control Room Area Chilled Water System, the
Auxiliary Building Filtered Ventilation Exhaust System, or the
Diesel Generators. During proposed single discharge header
operation, the NSWS will remain capable of fulfilling all of its
design basis requirements. No new accident causal mechanisms are
created as a result of NRC approval of this amendment request. No
changes are being made to the plant which will introduce any new
type of accident outside those assumed in the UFSAR.
Third Standard
Does operation of the facility in accordance with the proposed
amendment involve a significant reduction in the margin of safety?
Response: No.
Implementation of this amendment will not involve a significant
reduction in any margin of safety. Margin of safety is related to
the confidence in the ability of the fission product barriers to
perform their design functions during and following an accident
situation. These barriers include the fuel cladding, the reactor
coolant system, and the containment system. The performance of these
fission product barriers will not be impacted by implementation of
this proposed TS amendment. During single discharge header
operation, the NSWS and its supported systems will remain capable of
performing their required functions. No safety margins will be
impacted.
The PRA conducted for this proposed amendment demonstrated that
the impact on overall plant risk remains acceptable during single
discharge header operation. Therefore, there is not a significant
reduction in the margin of safety.
Based upon the preceding discussion, Duke Energy has concluded
that the proposed amendment does not involve a significant hazards
consideration.
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.

Exelon Generation Company, LLC, Docket No. 50-289, Three Mile Island
Nuclear Station, Unit 1, Dauphin County, Pennsylvania
Date of amendment request: March 26, 2012, as supplemented by
letter dated April 2, 2012.
Description of amendment request: The proposed amendment would
revise the Technical Specification (TS) Limiting Condition for
Operation 3.1.1.2, TS Surveillance Requirement 4.19.2, TS 6.9.6 ``Steam
Generator Tube Inspection Report,'' and TS 6.19 ``Steam Generator (SG)
Program,'' changing certain inspection periods and making other
administrative changes and clarifications. These proposed changes are
consistent with Technical Specification Task Force (TSTF) Traveler,
TSTF-510, Revision 2, ``Revision to Steam Generator Program Inspection
Frequencies and Tube Sample Selection.''
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No
The proposed change revises the Steam Generator (SG) Program to
modify the frequency of verification of SG tube integrity and SG
tube sample selection. A steam generator tube rupture (SGTR) event
is one of the design basis accidents that are analyzed as part of a
plant's licensing basis. The proposed SG tube inspection frequency
and sample selection criteria will continue to ensure that the SG
tubes are inspected such that the probability of a SGTR is not
increased. The consequences of a SGTR are bounded by the
conservative assumptions in the design basis accident analysis. The
proposed change will not cause the consequences of a SGTR to exceed
those assumptions. The proposed change to reporting requirements and
clarifications of the existing requirements have no affect on the
probability or consequences of SGTR.
Therefore, it is concluded that the proposed change does not
involve a significant increase in the probability or consequences of
an accident previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The proposed changes to the Steam Generator Program will not
introduce any adverse changes to the plant design basis or
postulated accidents resulting from potential tube degradation. The
proposed change does not affect the design of the SGs or their
[[Page 28632]]
method of operation. In addition, the proposed change does not
impact any other plant system or component.
Therefore, the proposed change does not create the possibility
of a new or different type of accident from any accident previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The SG tubes in pressurized water reactors are an integral part
of the reactor coolant pressure boundary and, as such, are relied
upon to maintain the primary system's pressure and inventory. As
part of the reactor coolant pressure boundary, the SG tubes are
unique in that they are also relied upon as a heat transfer surface
between the primary and secondary systems such that residual heat
can be removed from the primary system. In addition, the SG tubes
also isolate the radioactive fission products in the primary coolant
from the secondary system. In summary, the safety function of a SG
is maintained by ensuring the integrity of its tubes. Steam
generator tube integrity is a function of the design, environment,
and the physical condition of the tube. The proposed change does not
affect tube design or operating environment. The proposed change
will continue to require monitoring of the physical condition of the
SG tubes such that there will not be a reduction in the margin of
safety compared to the current requirements.
Therefore, it is concluded that the proposed change does not
involve a significant reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Pacific Gas and Electric Company, Docket Nos. 50-275 and 50-323, Diablo
Canyon Nuclear Power Plant, Units 1 and 2, San Luis Obispo County,
California
Date of amendment request: October 24, 2011.
Description of amendment request: The proposed amendment would
revise Technical Specification (TS) 3.3.5, ``Loss of Power (LOP) Diesel
Generator (DG) Start Instrumentation,'' to correct the nonconservative
first level undervoltage relays (FLUR) limits contained in Surveillance
Requirement (SR) 3.3.5.3; revise the Final Safety Analysis Report
Update (FSARU) Appendix 6.2D and Sections 6.3, 15.3, and 15.4; revise
the loss-of-coolant accident (LOCA) control room operator and offsite
dose analysis of record described in the FSARU; and provide a new
process for revising input values to this analysis.
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 change involve a significant increase in the
probability or consequences of an accident previously evaluated?
Response: No.
The diesel generators (DGs) provide a source of emergency power
when offsite power is either unavailable, or is degraded below a
point that would allow safe unit operation. Undervoltage protection
will generate a loss of power (LOP) DG start if a loss of voltage or
degraded voltage condition occurs on the 4.16 kV [kilovolt] vital
bus. The proposed technical specification (TS) change affects the
voltage at which an emergency bus that is experiencing sustained
degraded voltage will disconnect from offsite power and transfer to
the DGs. While the TS limits are revised, the function remains the
same and will continue to be performed. The first level undervoltage
relays (FLUR) and second level undervoltage relays (SLUR) will
continue to meet their required function to transfer 4.16 kV buses
to the DGs in the event of insufficient offsite power voltage. This
transfer will ensure that the class 1E equipment is capable of
performing its function to meet the requirements of the accident
analysis. The revised TS surveillance requirement (SR) 3.3.5.3
setpoints will not cause unnecessary separation of engineered safety
[feature] (ESF) loads from the 230 kV System. The proposed change
does not affect any accident initiators or precursors.
The ESF function delay times are bounding input parameters that
represent actual plant performance for when these ESF functions can
be credited to begin operating after an accident has already
occurred. The increased ESF delay times are not physically related
to the cause of any accident. Therefore, the increase in ESF delay
times do not introduce the possibility of a change in the frequency
of an accident previously evaluated. The revised LOCA control room
operator and offsite dose analysis results remain within the
applicable [General Design Criterion (GDC)] 19-1971 and 10 CFR 100
limits. Therefore, the proposed activity does not result in an
increase in the consequence of an accident previously evaluated in
the FSARU.
Therefore, the probability or consequences of any accident
previously evaluated will not be significantly increased as a result
of the proposed change.
2. Does the change create the possibility of a new or different
kind of accident from any accident previously evaluated?
Response: No.
No new accident scenarios, transient precursors, failure
mechanisms, or limiting single failures are introduced as a result
of the proposed change. The revised surveillance requirements will
continue to assure equipment reliability such that plant safety is
maintained or will be enhanced. An increased ESF delay time is not
an initiator of any accident and does not create any new system
interactions or failure modes of any structures, systems or
components (SSC).
Equipment important to safety will continue to operate as
designed. The changes do not result in adverse conditions or result
in any increase in the challenges to safety systems. Therefore,
operation of the Diablo Canyon Power Plant in accordance with the
proposed amendment will not create the possibility of a new or
different type of accident from any accident previously evaluated.
Therefore, the proposed change does not create the possibility
of a new or different accident from any accident previously
evaluated.
3. Does the change involve a significant reduction in a margin
of safety?
Response: No.
The DGs provide emergency electrical power to the safeguard
buses in support of equipment required to mitigate the consequences
of design basis accidents and anticipated operational occurrences,
including an assumed loss of all offsite power. SR 3.3.5.3 verifies
that the LOP DG start instrumentation channels respond to measured
parameters within the necessary range and accuracy. The proposed
amendment corrects nonconservative values in the TS limits for the
degraded voltage protection function. The proposed change to this SR
assures that design requirements of the emergency electrical power
system continue to be met.
There are no new or significant changes to the initial
conditions contributing to accident severity or consequences. The
proposed increase in ESF delay times is considered an analysis input
change. However, the safety analyses continue to meet all applicable
acceptance criteria. The proposed amendment will not otherwise
affect the plant protective boundaries, will not cause a release of
fission products to the public, nor will it degrade the performance
of any other SSCs important to safety.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the

Pacific Gas and Electric Company, Docket Nos. 50-275 and 50-323, Diablo
Canyon Nuclear Power Plant, Units 1 and 2, San Luis Obispo County,
California
Date of amendment request: January 25, 2012.
Description of amendment request: The proposed amendment would
revise the Diablo Canyon Power Plant, Units 1 and 2, Updated Final
Safety Analysis Report Update (UFSAR) Section 4.3.2.2, ``Power
Distribution,'' to allow use of the BEACON Power Distribution
Monitoring System methodology described in Westinghouse Electric
Company LLC (Westinghouse) WCAP-12472-P-A, Addendum 1-A, ``BEACON Core
Monitoring and Operations Support System,'' dated January 2000.
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 is to revise the Updated Final Safety
Analysis Report to allow the use of the BEACON code methodology
contained in WCAP-12472-P-A, Addendum 1-A. The BEACON code will be
used to perform core flux mapping to support the performance of
Technical Specification surveillances for power distribution limits
and the use of the BEACON code will not cause an accident.
No physical changes are being made to the plant. With the
change, Diablo Canyon Power Plant will continue to operate within
the power distribution limits contained in the plant Technical
Specifications.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The proposed change does not involve any physical changes to the
plant. The BEACON code performs flux mapping of the core and is not
used to control the performance of any plant equipment. Therefore,
use of the BEACON code cannot cause an accident. If it is determined
that the plant is not operating within the power distribution limits
during the performance of a Technical Specification Surveillance
using BEACON, then the applicable Technical Specification Condition
and Required Action(s) will be entered.
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.
With the use of the BEACON code methodology contained in WCAP-
12472-P-A, Addendum 1-A, the plant will continue to operate within
the power distribution limits contained in the plant Technical
Specifications. The use of the BEACON code does not involve any
changes to the fuel, reactor vessel, or containment fission product
barriers. The use of the BEACON code methodology includes
requirements for control of uncertainties associated with use of the
methodology and therefore there will be no impact on the accident
analyses that are contained in the Updated Final Safety Analysis
Report.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the

Tennessee Valley Authority, Docket No. 50-390, Watts Bar Nuclear Plant
(WBN), Unit 1, Rhea County, Tennessee
Date of amendment request: March 8, 2012.
Description of amendment request: The proposed amendment would
revise (1) Technical Specification (TS) 3.3.7, ``Control Room Emergency
Ventilation System (CREVS) Actuation Instrumentation,'' by changing the
Allowable Value for the main control room air intake radiation
monitoring instrumentation in Table 3.3.7-1 from <= 9.45E-05 micro-
Curie/cubic centimeter ([micro]Ci/cc) (3,308 counts per minute (cpm))
to <= 1.647E-04 [micro]Ci/cc (3,308 cpm); and (2) TS 3.4.16, ``RCS
[reactor coolant system] Specific Activity,'' by lowering the DOSE
EQUIVALENT 1-131 spike limit from 21 micro-Curie/gram ([micro]Ci/gm) to
14 [micro]Ci/gm in Required Action A.1 and Condition C.
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 consequence of an accident previously evaluated?
Response: No.
The proposed TS changes do not adversely affect any fission
product barrier nor do they alter the safety function of safety
systems, structures, or components, or their roles in accident
prevention or mitigation. They do not change any credited operator
actions nor do they physically change any plant system, structure,
or component. The amount of iodine in the primary coolant and the
Allowable Value for the main control room radiation monitors do not
affect the initiation of any accident or transient. Therefore, the
proposed amendment does not result in a significant increase in the
probability of an accident previously evaluated. The changes do not
adversely affect the protective and mitigative capabilities of the
plant. The SSCs [structures, systems, and components] will continue
to perform their intended safety functions. The proposed reduction
in the amount of DOSE EQUIVALENT 1-131 (DEI-131) in the reactor
coolant following a load transient has no impact on any plant
configuration or system performance relied upon to mitigate the
consequences of an accident.
The calculated radiological doses remain within the limits
prescribed in 10 CFR Part 100 and GDC-19 [General Design Criterion
19 of Appendix A to 10 CFR Part 50] and are consistent with the
methodology and acceptance criteria of Section 15.6.3 of NUREG-0800
and Appendix A of Section 15.1.5 of NUREG-0800.
The change to the Allowable Value for the main control room
radiation monitors continues to ensure that the monitors are capable
of performing their intended design function of isolating the main
control room subsequent to an accident.
Therefore, the proposed amendment does not involve a significant
increase in the consequences of an accident previously evaluated.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
The proposed TS changes do not alter the configuration of the
plant nor do they directly affect plant operation. The proposed TS
changes do not result in the installation of any new equipment or
system or the modification of any existing equipment or systems. No
new operation procedures, conditions, or modes are created. As a
result, the proposed TS changes do not introduce any new failure
mechanisms, malfunctions, or accident initiators not already
considered in the design and licensing basis. There will be no
adverse effects or challenges imposed on any safety-related system
as a result of these changes.
Therefore, the proposed amendment does not create the
possibility of a new or different kind of accident from any
previously evaluated.
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
Response: No.
The calculated radiological doses remain within the limits
prescribed in 10 CFR Part 100 and GDC-19, and are consistent with
the methodology and acceptance criteria of
[[Page 28634]]
Section 15.6.3 of NUREG-0800 and Appendix A of Section 15.1.5 of
NUREG-0800. The Allowable Value for the main control room radiation
monitor continues to ensure that the monitors are capable of
performing their intended design function of isolating the main
control room subsequent to an accident.
Therefore, the proposed amendment does not involve a significant
reduction in the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
