UNITED STATES NUCLEAR REGULATORY COMMISSION PORTLAND GENERAL ELECTRIC COMPANY. ET. AL.
TROJAN NUCLEAR PLANT DFJET NO. 50-344 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (NRC) is considering issuance' of an exemption to f acility Operating License No. NPF-1, issued to Portland General Electric Company (PGE or the licensee), for the Trojan Nuclear Plant, a permanently shutdown plant, located in Columbia County, Oregon, on the west bank of the Columbia River.
l ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action:
The proposed action would grant an exemption from certain safeguards requirements of Title 10 of Part 73.55 of the Code of Federal Regulations (10 CFR 73.55), " Requirements for physical protection of licensed activities in nuclear power reactors against radiological sabotage." The licensee requested the exemption in a letter dated June 17, 1993.
The Need for the Proposed Action:
The requirements of 10 CFR 73.55 were promulgated to provide protection of a facility against a design basis sabotage threat in consideration of the conditions associated with an operational power reactor.
However, the Trojan Nuclear Plant (TNP) has permanently ceased power operation and all nuclear fuel has been removed from the containment to the spent fuel pool. On i
March 24, 1993, the NRC staff issued a confirmatory order that prohibits the l
licensee from placing any nuclear fuel into the Trojan Nuclear Plant reactor building without prior approval in writing from the NRC.

I
-g.
May 5,1993, the NRC staff is.;ued an amendment to the license for the Trojan Nuclear Plant that allows PGE to possess, but not operate, the nuclear plant.
When compared to an operational power reactor facility, the status of TNP provides a significantly reduced risk from a radiological release as a consequence of sabotage. The range of credible accidents and accident consequences for TNP are reduced because of its shutdown and defueled condition. The facility has not operated for nearly a year and radioactive decay has significantly reduced the radionuclide inventory and decay heat level of the spent fuel. The Defueled Security Plan provides an adequate basis for an acceptable safeguards program.
Environmental Impacts of the ProDosed Action:
The proposed action does not involve any measurable environmental impacts, since the facility configuration or plant operations will not change.
PGE conducted a safety analysis in support of the exemption request which I
documents that there is no credible act of radiological sabotage that would result in radiation doses greater than the Environmental Protection Agency Protective Action Guides.
The NRC staff, based on independent evaluation, agrees with the licensee analyses and concludes that sufficient bases have been presented that the j
consequences of radiological sabotage which may potentially result in a radiological release are greatly decreased for the Trojan Nuclear Plant given the permanently shutdown and defueled status of the facility.
Therefore, the proposed action does not increase the probability or consequences of any accidents, no changes are being made in the types of any 4
t v j effluents that may be released offsite, and there is no significant increase in the allowable individual or cumulative occupational radiation exposure onsite.
Accordingly, the Commission concludes that this proposed action would result in no significant radiological environmental impact.
With regard to potential non-radiological impacts, the proposed action does not affect non-radiological plant effluents and has no other environmental impact. Therefore, the Commission concludes that there are no significant non-radiological environmental impacts associated with the proposed action.
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.
The principal alternative would be to deny the action.
This would not reduce environmental impacts of plant operation and would not enhance the t
protection of the environment nor public health and safety.
Alternative Use of Resources:
This action does not involve the use of any resources not previously i
considered in the Final Environmental Statement for the Trojan Nuclear Plant, dated August 1973.
Agencies and Persons Consulted:
The NRC staff consulted with representatives of the State of Oregon Department of Energy regarding the environmental impact of the proposed
]
action.
The State representatives had no comment.
i i
r
.- ; FINDING OF NO SIGNIFICANT IMPACT:
The Commission has determined not to prepare an environmental impact statement for the proposed exemption.
Based upon the foregoing environmental assessment, the Commission concludes that the proposed action will not have a significant effect on the quality of the human environment.
For further details with respect to this action, see the licensee application for exemption dated June 17, 1993, which is available for public inspection at the Commission Public Document Room, Gelman Building, 2120 L Street, N.W., Washington, D.C. 20555, and at the Local Public Document Room for the Trojan Nuclear Plant at the Branford Price Millar Library, Portland State University, Portland, Oregon 97207.
Dated at Rockville, Maryland, this 27th day of September 1993.
