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.
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.
With regard to potential non-radiological 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 ``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.
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.
