NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-445 and 50-446]
Texas Utilities Electric Co.; Environmental Assessment and
Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of an exemption from the requirements of 10 CFR
50.71(e)(3)(i) to Texas Utilities Electric Company (the licensee) for
the Comanche Peak Steam Electric Station, Unit Nos. 1 and 2, located in
Somervell County, Texas.
Environmental Assessment
Identification of Proposed Action
Section 50.71(e)(3)(i) of title 10 of the Code of Federal
Regulations requires the licensees of nuclear power reactors to submit
an Updated Final Safety Analysis Report (UFSAR). The UFSAR is defined
as ``a revision of the original FSAR [Final Safety Analysis Report]
containing those original pages that are still applicable plus new
replacement pages.'' By letter dated October 14, 1993, the licensee
requested an exemption from 10 CFR 50.71(e) that would eliminate the
requirement to resubmit those original pages of the FSAR that are still
applicable when submitting the UFSAR.
The licensee has maintained the FSAR current since the original
FSAR submittal in 1978 to the present by issuing amendments to the
FSAR, which contain new replacement pages, approximately every three
months. The licensee has committed to maintain the FSAR using this
process until the issuance of the UFSAR. The final amendment to the
FSAR, containing only replacement pages, would convert the FSAR to the
UFSAR. The amendment to convert the FSAR to the UFSAR would be
submitted by February 2, 1995.
The Need for the Proposed Action
Section 50.71(e) requires that licensee submit, within two years of
receiving an operating license, a UFSAR that contains the original FSAR
pages that are still applicable and new replacement pages. The purpose
of this requirement is to assure that the Final Safety Analysis Report
is updated to contain the latest material developed.
The Comanche Peak Steam Electric Station FSAR is approximately
7,500 to 8,000 pages of text and tables, and 1,500 to 2,000 sheets of
figures. As the licensee has maintained the FSAR current by frequent
amendments, the vast majority of this material does not require
revision and the number of new replacement pages associated with the
UFSAR submittal would be relatively small. Thus, the CPSES FSAR meets
the intent of 10 CFR 50.71(e) for issuance of the UFSAR because it
contains the latest material developed.
Therefore, an exemption is warranted since the licensee has
maintained the FSAR in a manner that is consistent with the underlying
purpose of issuing the UFSAR in accordance with 10 CFR 50.71(e).
Environmental Impact of the Proposed Action
The proposed exemption affects only the size of the UFSAR submittal
and does not affect the risk of facility accidents. Thus, post-accident
radiological releases will not differ from those determined previously,
and the proposed exemption does not otherwise affect facility
radiological effluents, or any significant occupational exposures. With
regard to potential nonradiological impacts, the proposed exemption
does not affect plant nonradiological effluents and has no other
environmental impact. Therefore, the Commission concludes that there
are no measurable radiological or nonradiological environmental impacts
associated with the proposed exemption.
Alternatives to the Proposed Action
Since the Commission has concluded there is no measurable
environmental impact associated with the proposed exemption, any
alternatives either will have no environmental impact or will have a
greater environmental impact. The principal alternative to the
exemption would be to require that the licensee submit the original
FSAR pages that are still applicable with the UFSAR replacement pages.
Such an action would not enhance the protection of the environment.
Alternative Use of Resources
This action does not involve the use of resources not considered
previously in the Final Environmental Statement for Comanche Peak Steam
Electric Station, Units 1 and 2, dated September 1981, and Supplement
dated October 1989.
Agencies and Persons Contacted
The NRC staff reviewed the licensee's request. The staff consulted
with the State of Texas regarding the environmental impact of the
proposed action.
Finding of No Significant Impact
The Commission has determined not to prepare an environmental
impact statement for the proposed exemption. On the basis of the
environmental assessment, we conclude that the proposed action will not
have a significant effect on the quality of the human environment.
For further details with respect to the proposed action, see the
licensee's letter dated October 14, 1993, which is available for public
inspection at the Commission's Public Document Room, the Gelman
Building, 2120 L Street, NW., Washington, DC 20555 and at the
University of Texas at Arlington Library, Government Publications/Maps,
701 South Cooper, P.O. Box 19297, Arlington, Texas 76019.
Dated at Rockville, Maryland, this 30th day of March 1994.
