7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION PORTLAND GENERAL ELECTRIC COMPANY IHE CITY OF EUGENE. OREGON PACIFIC POWER AND LIGHT COMPANY QQCEET NO. 50-384 IROJAN NUCLEAR PLMT ENVIRONMENTAL ASSE15fiENT AND FINDING OF NQ SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Comission) is considering issuance of a one time schedular exemption from the requirements of 10 CFR 50, Appendix E. (IV)(F)(2) to Portland General Electric Company, et al.,
(the licensee), for Facility Operating License No. NPF-1, for operation of the Trojan Nuclear Plant located in Columbia County, Oregon.
ENVIRONMENTAL ASSESSMENT Identification of PropAsid _fttion The proposed action would grant a one time schedular exemption from the requirement of 10 CFR 50, Appendix E, (IV)(F)(2) to annually exercise its emergency plan. By letter dated December 11, 1992, the licensee requested an exemption from 10 CFR 50, Appendix E (IV)(F)(2) which would defer conducting its annual emergency plan exercise scheduled for December 15, 1992, until the first quarter of 1993.
Ihe Need for the Proposed Action Title 10 of the Code of Federal Regulations, Part 50, Appendix E.
Paragraph IV, Section F Item 2 requires that each licensee annually exercise its emergency plan. The 1992 annual exercise for Trojan Nuclear Plant was initially scheduled for November 17, 1992. The licensee had f$kUS$o$
p o$o$0$44 PDR
. . completed necessary preparation for this exercise. However, the Trojan Nuclear Plant experienced a steam generator tube leak that resulted in a plant shutdown Novemeber 9, 1992. The licensee does not expect the plant to startup until after January 1, 1993. As a result of the steam generator tube leak and subsequent plant shutdown, the initial scheduled date of November 17, 1992, was deferred until December 15, 1992. The licensee undertook the necessary preparatory actions to conduct the annual exercise on this date. However, as a result of the continued forced outage, the annual exercise could not be practicably performed on December 15, 1992. The current forced outage for steam generator eddy current inspection requires the reactor coolant system to be operated in a reduced inventory condition. Due to the potential impact on plant personnel and the outage duration, the licensee considers it prudent to conduct emergency plan exercises at times other than while the plant is in reduced inventory.
The combination of added workload on the remaining plant staff and the economic impact from the potential outage extension, make the performance of the 1992 annual exercise on its scheduled date of December 15, 1992, an undue hardship. The one time exemption from the annual requirement will allow the licensee to defer the exercise until the first quarter of 1993.
Environmental Imoact of the Proposed Action The proposed exemption affects only the licensee's required date for conducting the annual emergency plan exercise. 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
, - 3-
. plant nonradiological effluents and has no other environmental impact.
Therefore, the Comission concludes that there are no measurable radiological or nonradiological environmental impacts associated with the !
proposed exemption.
Alternative to the Proposed Action Since the Comission concluded that there are no significant environmental effects that would result from the proposed action, any alternatives with equal or greater environmental impacts need not be evaluated.
The principal alternative would be to deny the requested exemption.
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 resources not previously considered in the Final Environmental Statement related to operation of.the +
Trojan Nuclear Plant, dated August 1973. '
Aaencies and Persons Consulted The NRC staff reviewed the licensee's request and did not consult other agencies or persons. -i FINDING OF NO SIGNIFICANT IMPACT The Comission has determined not-to prepare an environmental impact statement for the proposed exemption.
Based upon the foregoing environmental assessment, the-Comission ,
concludes that the proposed action will not have a significant effect on-the quality of the human environment. .
