NUCLEAR REGULATORY COMMISSION
[Docket No. 50-285]
Omaha Public Power District, Fort Calhoun Station, Unit No. 1;
Environmental Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of an amendment to Facility Operating License No.
DPR-40, issued to Omaha Public Power District (the licensee), for
operation of the Fort Calhoun Station, Unit 1, located in Washington
County, Nebraska.
Environmental Assessment
Identification of the Proposed Action
The proposed action would issue an amendment to allow an increase
in the initial nominal Uranium-235 (U-235) enrichment limit for fuel
assemblies which may be stored in the spent fuel pool. This action
would allow the licensee to extend the biennial interval until the
first quarter of 1996. The proposed action is in accordance with the
licensee's application for amendment dated February 1, 1996.
The Need for the Proposed Action
The licensee intends to store unirradiated fuel with a maximum
initial enrichment of 4.5 w/o U-235 in Region 1 of the spent fuel pool
during the next refueling outage (Refuel 17). Spent fuel will be stored
in Region 2 of the spent fuel pool. At present, fuel with a maximum
initial enrichment up to 4.2 weight percent of U-235 can be stored in
Region 1 and Region 2 of the spent fuel pool.
Environmental Impact of the Proposed Action:
The Commission has completed its evaluation of the proposed
revision to the technical specifications (TSs) and concludes that the
use of fuel with a maximum enrichment of 4.5 w/o U-235 would not
significantly increase the probability or consequences of any accident
previously analyzed. The proposed amendment would increase the
allowable fuel enrichment from 4.2 w/o to 4.5 w/o U-235 in Region 1 of
the spent fuel pool and modify the burnup/enrichment restrictions
imposed on fuel stored in Region 2 to include fuel with an enrichment
up to 4.5 w/o.
The environmental impacts of transportation resulting from the use
of higher enrichment and extended irradiation are discussed in the
staff assessment entitled ``NRC Assessment of the Environmental Effects
of Transportation Resulting from Extended Fuel Enrichment and
Irradiation.'' This assessment was published in the Federal Register on
August 11, 1988 (53 FR 30355) as corrected on August 24, 1988 (53 FR
32322) in connection with the Shearon Harris Nuclear Power Plant, Unit
1: Environmental Assessment and Finding of No Significant Impact. As
indicated therein, the environmental cost contribution of an increase
in fuel enrichment of up to 5 weight percent U-235 and irradiation
limits of up to 60 Gigawatt Days per Metric Ton (GWD/MT) 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). These findings are applicable to the
proposed amendment for the Ft. Calhoun Station, Unit 1. Accordingly,
the Commission concludes that this proposed action would result in no
significant radiological environmental impact.
With regard to potential nonradiological impacts, the proposed
changes involve systems located within the restricted area as defined
in 10 CFR Part 20. It does not affect nonradiological plant effluents
and has no other environmental impact. Therefore, the Commission
concludes that there are no significant nonradiological environmental
impacts associated with the proposed amendment.
The Notice of Consideration of Issuance of Amendment to Facility
Operating License, Proposed No Significant Hazards Consideration
Determination, and Opportunity for a Hearing in connection with this
action was published in the Federal Register on March 13, 1996 (61 FR
10396).
Alternative to the Proposed Action
Since the Commission concluded that there are no significant
environmental effects that would result from the proposed action, any
alternative with equal or greater environmental impacts need not be
evaluated.
[[Page 31562]]
The principal alternative would be to deny the requested amendment.
This would not reduce environmental impacts of plant operation and
would result in reduced operational flexibility.
Alternative Use of Resources
This action does not involve the use of any resources not
previously considered in the Final Environmental Statement (FES) for
the Fort Calhoun Station, Unit 1, dated August 1972.
Agencies and Persons Consulted
In accordance with its stated policy, on June 13, 1996, the staff
consulted with the Nebraska State official, Ms. Cheryl Rodgers of the
Department of Health, 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 action.
For further details with respect to the proposed action, see the
licensee's letter dated February 1, 1996, which is 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 W. Dale Clark Library, 215 South 15th
Street, Omaha, Nebraska 68102.
Dated at Rockville, Maryland, this 14th day of June 1996.
For the Nuclear Regulatory Commission.

Project Manager, Project Directorate IV-2, Division of Reactor Projects
III/IV, Office of Nuclear Reactor Regulation.
