Luminant Generation Company, LLC.,
Combined License Application for
Comanche Peak Nuclear Power Plant,
Units 3 and 4, Environmental
Assessment and Finding of No
Significant Impact
wreier-aviles on DSK5TPTVN1PROD with NOTICES
The U.S. Nuclear Regulatory
Commission (NRC) is considering
issuance of an exemption from Section
50.71(e)(3)(iii) of Title 10 of the Code of
Federal Regulations (10 CFR), for the
Comanche Peak Nuclear Power Plant
(CPNPP), Units 3 and 4, Combined
License (COL) Application, Docket
Numbers 52–034 and 52–035, submitted
by Luminant Generation Company, LLC.
(Luminant) for the proposed facility to
be located in Somervell County, Texas.
In accordance with 10 CFR 51.21, the
NRC is issuing this environmental
assessment and finding of no significant
impact.
Environmental Assessment—
Identification of the Proposed Action
The proposed action is a one-time
schedule exemption from the
requirements of 10 CFR 50.71(e)(3)(iii).
During the period from the docketing of
a COL application until the NRC makes
a finding under 10 CFR 52.103(g)
pertaining to facility operation,
Luminant must, pursuant to 10 CFR
50.71(e)(3)(iii), submit an annual update
to the Final Safety Analysis Report
(FSAR). The proposed exemption would
allow Luminant to submit its COL
application FSAR update, scheduled for
June 2013, on or before November 30,
2013, and to submit the subsequent
FSAR annual update in November 2014.
The current FSAR update schedule
could not be changed, absent the
exemption. The NRC is authorized to
grant the exemption pursuant to 10 CFR
50.12.
VerDate Mar<15>2010
14:21 Apr 30, 2013
Jkt 229001
The proposed action is in accordance
with Luminant’s request dated January
28, 2013, and can be found in the
Agencywide Documents Access and
Management System (ADAMS) under
Accession No. ML13031A041.
Need for the Proposed Action
Since the CPNPP, Units 3 and 4, COL
application references the US–APWR
DCD, the proposed action is needed in
order to provide Luminant sufficient
time to fully incorporate into the COL
application (COLA) FSAR, Revision 4 of
the United States—Advanced
Pressurized Water Reactor (US–APWR)
Design Control Document (DCD), which
Mitsubishi Heavy Industries Ltd. plans
to submit to the NRC on or before
August 31, 2013. Luminant has
requested a one-time exemption from
the requirements specified in 10 CFR
50.71(e)(3)(iii) in order to reduce the
burden associated with identifying all
committed changes that were made to
the DCD, since Revision 3 to the US–
APWR DCD.
The only alternative would be not
issuing the exemption. Because this
alternative would require Luminant to
issue COLA FSAR, Revision 4 between
US–APWR DCD, Revisions 3 and 4,
Luminant would need to identify all
changes made since the issuance of US–
APWR DCD, Revision 3, and revise the
COLA FSAR to account for any changes
that have not yet been incorporated into
US–APWR DCD, Revision 4.
Additionally, the NRC reviewers would
need to review US–APWR DCD,
Revision 3, identify all committed
changes to the COLA FSAR, and review
all Updated Tracking Reports in order to
understand how COLA Revision 4 is
linked to the latest US–APWR DCD
revision.
Environmental Impacts of the Proposed
Action
The NRC has completed its evaluation
of the proposed action and concludes
that there are no environmental impacts
associated with the proposed
exemption. The proposed exemption is
solely administrative in nature in that it
pertains to the schedule for submittal to
the NRC of revisions to a COL
application under 10 CFR Part 52.
The proposed action will not increase
the probability or consequences of
accidents. No changes are being made in
the types of effluents that may be
released offsite. There is no increase in
the amount of any effluent released
offsite. There is no increase in
occupational or public radiation
exposure. Therefore, there are no
radiological environmental impacts
associated with the proposed action.

Frm 00073
Fmt 4703
Sfmt 4703
With regard to potential nonradiological impacts, the proposed
action does not have any foreseeable
impacts to land, air, or water resources,
including impacts to biota. In addition,
there are also no known socioeconomic
or environmental justice impacts
associated with the proposed action.
Therefore, there are no non-radiological
environmental impacts associated with
the proposed action. Accordingly, the
NRC concludes that there are no
environmental impacts associated with
the proposed action.
Environmental Impacts of the
Alternatives to the Proposed Action
As an alternative to the proposed
action, the NRC staff considered denial
of the proposed action (i.e., the ‘‘noaction’’ alternative). Denial of the
application would result in no change
in current environmental impacts.
Therefore, the environmental impacts of
the proposed action and the alternative
action are similar.
Alternative Use of Resources
The proposed action does not involve
the use of any different resources than
those previously considered in NUREG–
1943, ‘‘Final Environmental Impact
Statement for Combined Licenses
(COLs) for Comanche Peak Nuclear
Power Plant, Units 3 and 4,’’ dated May
13, 2011.
Agencies and Persons Consulted
On March 11, 2013, the NRC staff
consulted with an official from the
Texas Department of State Health
Services (DSHS), Radiation Inspection
Branch regarding the environmental
impact of the proposed action. The
representative from the Texas DSHS had
no comments.
Finding of No Significant Impact
On the basis of the environmental
assessment, the NRC concludes that the
proposed action will not have an effect
on the quality of the human
environment. Accordingly, the NRC has
determined not to prepare an
environmental impact statement for the
proposed action.

SUPPLEMENTARY INFORMATION:
Background Information
The NRC issues LR–ISGs to
communicate insights and lessons
learned and to address emergent issues
not covered in license renewal guidance
documents, such as the GALL Report
and SRP–LR. In this way, the NRC staff
and stakeholders may use the guidance
in an LR–ISG document before it is
incorporated into a formal license
renewal guidance document revision.
The NRC staff issues LR–ISGs in
accordance with the LR–ISG Process,
Revision 2 (ADAMS Accession No.
ML100920158), for which a notice of
availability was published in the
Federal Register on June 22, 2010 (75
FR 35510).
The NRC staff developed LR–ISG–
2012–01 to: (a) Revise the definition of
‘‘wall thinning’’ to include erosion
PO 00000
Frm 00074
Fmt 4703
Sfmt 4703
25487
mechanisms; (b) revise the definition of
‘‘flow-accelerated corrosion’’ and
‘‘erosion’’ to align them with the
definitions commonly used in industry;
(c) allow applicants to monitor wall
thinning caused by erosion mechanisms
in the AMP for flow-accelerated
corrosion by (i) ensuring that extent of
condition reviews identify any other
components susceptible to similar
degradation, and (ii) verifying that
corrective actions have either
eliminated the erosion mechanism,
precluding the need for ongoing aging
management activities, or included
periodic wall thickness measurements
in an AMP; and (d) make miscellaneous
and editorial changes.
On July 13, 2012 (77 FR 41457), the
NRC requested public comments on
draft LR–ISG–2012–01. In response, the
Nuclear Energy Institute (NEI) provided
comments by letter dated August 27,
2012 (ADAMS Accession No.
ML12244A004), which integrated
multiple industry comments on the
subject LR–ISG, including those
submitted separately by Wolf Creek
Nuclear Operating Corporation in a
letter dated August 23, 2012 (ADAMS
Accession No. ML12250A668). No other
comments were submitted.
NEI’s comments broadly
recommended that the NRC create a
separate AMP for mechanical erosion
mechanisms, rather than mixing these
phenomena into the existing FlowAccelerated Corrosion program. The
industry believed that the change
proposed by the NRC would cause
confusion in the current FlowAccelerated Corrosion programs because
of different susceptibility criteria and
inspection selection methods and
strategies for erosion mechanisms.
The NRC considered these comments
in developing the final LR–ISG, but
ultimately determined that the LR–ISG
should be published in its current
format. The staff notes that no applicant
for a renewed licensee has ever
proposed a separate AMP to address
erosion mechanisms, but they have
included activities for managing erosion
mechanisms in either the FlowAccelerated Corrosion or the OpenCycle Cooling Water System AMPs. The
NRC staff has approved both
approaches, and in that regard, LR–ISG–
2012–01 is consistent with existing
industry and NRC practice. The staff
further notes that it has not detected any
confusion, as postulated by the
industry, on the part of licensees that
have chosen to include erosion
mechanisms in the Flow-Accelerated
Corrosion program. Detailed responses
to the comments can be found in
Appendix E of the final LR–ISG.

NUCLEAR REGULATORY COMMISSION
[Docket Nos.: 52-034 and 52-035; NRC-2008-0594]
Luminant Generation Company, LLC., Combined License Application
for Comanche Peak Nuclear Power Plant, Units 3 and 4, Environmental
Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (NRC) is considering
issuance of an exemption from Section 50.71(e)(3)(iii) of Title 10 of
the Code of Federal Regulations (10 CFR), for the Comanche Peak Nuclear
Power Plant (CPNPP), Units 3 and 4, Combined License (COL) Application,
Docket Numbers 52-034 and 52-035, submitted by Luminant Generation
Company, LLC. (Luminant) for the proposed facility to be located in
Somervell County, Texas. In accordance with 10 CFR 51.21, the NRC is
issuing this environmental assessment and finding of no significant
impact.
Environmental Assessment--Identification of the Proposed Action
The proposed action is a one-time schedule exemption from the
requirements of 10 CFR 50.71(e)(3)(iii). During the period from the
docketing of a COL application until the NRC makes a finding under 10
CFR 52.103(g) pertaining to facility operation, Luminant must, pursuant
to 10 CFR 50.71(e)(3)(iii), submit an annual update to the Final Safety
Analysis Report (FSAR). The proposed exemption would allow Luminant to
submit its COL application FSAR update, scheduled for June 2013, on or
before November 30, 2013, and to submit the subsequent FSAR annual
update in November 2014. The current FSAR update schedule could not be
changed, absent the exemption. The NRC is authorized to grant the
exemption pursuant to 10 CFR 50.12.
The proposed action is in accordance with Luminant's request dated
January 28, 2013, and can be found in the Agencywide Documents Access
and Management System (ADAMS) under Accession No. ML13031A041.
Need for the Proposed Action
Since the CPNPP, Units 3 and 4, COL application references the US-
APWR DCD, the proposed action is needed in order to provide Luminant
sufficient time to fully incorporate into the COL application (COLA)
FSAR, Revision 4 of the United States--Advanced Pressurized Water
Reactor (US-APWR) Design Control Document (DCD), which Mitsubishi Heavy
Industries Ltd. plans to submit to the NRC on or before August 31,
2013. Luminant has requested a one-time exemption from the requirements
specified in 10 CFR 50.71(e)(3)(iii) in order to reduce the burden
associated with identifying all committed changes that were made to the
DCD, since Revision 3 to the US-APWR DCD.
The only alternative would be not issuing the exemption. Because
this alternative would require Luminant to issue COLA FSAR, Revision 4
between US-APWR DCD, Revisions 3 and 4, Luminant would need to identify
all changes made since the issuance of US-APWR DCD, Revision 3, and
revise the COLA FSAR to account for any changes that have not yet been
incorporated into US-APWR DCD, Revision 4. Additionally, the NRC
reviewers would need to review US-APWR DCD, Revision 3, identify all
committed changes to the COLA FSAR, and review all Updated Tracking
Reports in order to understand how COLA Revision 4 is linked to the
latest US-APWR DCD revision.

resources, including impacts to biota. In addition, there are also no
known socioeconomic or environmental justice impacts associated with
the proposed action. Therefore, there are no non-radiological
environmental impacts associated with the proposed action. Accordingly,
the NRC concludes that there are no environmental impacts associated
with the proposed action.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed action, the NRC staff considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Denial of the application would result in no change in current
environmental impacts. Therefore, the environmental impacts of the
proposed action and the alternative action are similar.
Alternative Use of Resources
The proposed action does not involve the use of any different
resources than those previously considered in NUREG-1943, ``Final
Environmental Impact Statement for Combined Licenses (COLs) for
Comanche Peak Nuclear Power Plant, Units 3 and 4,'' dated May 13, 2011.
