NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-369 and 50-370]
Duke Power Company, et al., McGuire Nuclear Station, Unit Nos. 1
and 2; Environmental Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of amendments to Facility Operating License Nos.
NPF-9 and NPF-17, issued to Duke Power Company (the licensee), for
operation of the McGuire Nuclear Station, Units 1 and 2, located in
Mecklenburg County, North Carolina.
Environmental Assessment
Identification of the Proposed Action
The proposed action would change the Technical Specifications (TS)
to (a) allow the maximum enrichment for fuel stored in the fuel pools
to increase from a nominal value of 4.0 to 5.0 weight percent Uranium-
235, (b) establish new loading patterns for new and irradiated fuel in
the spent fuel pool to accommodate this increase, (c) add a TS to
establish a limit for boron concentration for all modes of operation,
(d) add BASES to correspond to the TS that were added, (e) add TS to
reflect limits for fuel storage criticality analysis, and (f) reformat
the TS to bring them more in line with the standard format in the NRC
report NUREG-1431, ``Standard Technical Specifications Westinghouse
Plants.''
The proposed action is in accordance with the licensee's
application for amendment dated June 13, 1994, as supplemented by
letters dated August 15, 1994, March 23 and April 18, 1995.
The Need for the Proposed Action
The proposed action is needed so that the licensee can use higher
fuel enrichment to provide additional flexibility in the licensee's
reload design efforts and to increase the efficiency of fuel storage
cell use in the spent fuel pools.
Environmental Impacts of the Proposed Action
The Commission has completed its evaluation of the proposed
revisions to the TS. The proposed revisions would permit storage of
fuel enriched to a nominal 5.0 weight percent Uranium-235. The safety
considerations associated with storing new and spent fuel of a higher
enrichment have been evaluated by the NRC staff. The staff has
concluded that such changes would not adversely affect plant safety.
The
[[Page 44088]]
proposed changes have no adverse effect on the probability of any
accident. No changes are being made in the types or amounts of any
radiological effluents that may be released offsite. There is no
significant increase in the allowable individual or cumulative
occupational radiation exposure.
The environmental impacts of transportation resulting from the use
of higher enrichment fuel and extended irradiation were published and
discussed in the staff assessment entitled, ``NRC Assessment of the
Environmental Effects of Transportation Resulting from Extended Fuel
Enrichment and Irradiation,'' dated July 7, 1988, and published in the
Federal Register (53 FR 30355) on August 11, 1988, as corrected on
August 24, 1988 (53 FR 32322), in connection with Shearon Harris
Nuclear Power Plant, Unit 1: Environmental Assessment and Finding of No
Significant Impact. As indicated therein, the environmental cost
contribution of the proposed increase in the fuel enrichment and
irradiation limits are either unchanged or may, in fact, be reduced
from those summarized in Table S-4 as set forth in 10 CFR 51.52(c). The
results of the Shearon Harris assessment are applicable to McGuire,
Units 1 and 2. Accordingly, the Commission concludes that there are no
significant radiological environmental impacts associated with the
proposed amendment.
With regard to potential nonradiological impacts, the proposed
action involves features located entirely within the restricted area as
defined in 10 CFR Part 20. It does not affect nonradiological plant
effluents and has no other environmental impact. Accordingly, the
Commission concludes that there are no significant nonradiological
environmental impacts associated with the proposed action.
Alternatives to the Proposed Action
Since the Commission has concluded there is no measurable
environmental impact associated with the proposed exemption, any
alternatives with equal or greater environmental impact need not be
evaluated. The principal alternative to this action would be to deny
the request for exemption. Such action would not reduce the
environmental impacts of plant operations.
Alternative Use of Resources
This action does not involve the use of resources not previously
considered in the ``Final Environmental Statement Related to the
Operation of McGuire Nuclear Station Units 1 and 2,'' dated April 1976
and its addendum dated January 1981.
Agencies and Persons Consulted
In accordance with its stated policy, on August 17, 1995, the NRC
staff consulted with the North Carolina State official, Mr. Dayne H.
Brown, Director, Department of Environmental Health and Natural
Resources, Division of Radiation Protection, regarding the
environmental impact of the proposed action. The State official had no
comments.
Finding of No Significant Impact
Based upon the environmental assessment, the Commission concludes
that the proposed action will not have a significant effect on the
quality of the human environment. Accordingly, the Commission has
determined not to prepare an environmental impact statement for the
proposed exemption.
For further details with respect to this action, see the licensee's
letter dated June 13, 1994, as supplemented by letters dated August 15,
1994, March 23 and April 18, 1995, which are available for public
inspection at the Commission's Public Document Room, The Gelman
Building, 2120 L Street, NW., Washington, DC, and at the local public
document room located at the Atkins Library, University of North
Carolina, Charlotte (UNCC), North Carolina.
Dated at Rockville, Maryland, this 17th day of August 1995.
For the Nuclear Regulatory Commission.
Louis L. Wheeler,
Acting Director, Project Directorate II-2, Division of Reactor
Projects--I/II, Office of Nuclear Reactor Regulation.
