' UNITED STATES NUCLEAR REGULATORY COMMISSION. ,
PORTLAND GENERAL ELECTRIC COMPANY, ET. AL.
DOCKET'.NO. 50-344.
NOTICE OF ISSUANCE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT: IMPACT The United States Nuclear Regulatory Commission (the' Comission) is considering the issuance of exemptions from specific requirements in Appendix'R to 10 CFR 50 to Portland General Electric Company, et. al. (PGE.:the licensee) q for the Trojan Nuclear Plant located in Columbia County ' Oregon. '
ENVIRONMENTAL ASSESSMENT I_ identification of the Proposed Action: The exemptions are related to Section III.G.2 of Appendix R to 10 CFR Part 50, " Fire Protection Program for.. Nuclear Power Facilities Operating Prior to January 1, ~1979." -Section III.G of-Appendix R requires fire protection for equipment important to safe. shutdown. - '
Such fire protection is achieved by various combinations of fire barriers, fire suppression systems, fire detectors, and separation of safety trains-(III.G.2)oralternatesafeshutdownequipmentindependentofthefirearea (III.G.3). The objective of this protection is to assure that one train of equipment needed for hot shutdown would be undamaged by fire, and that' systems needed for cold shutdown could be repaired within 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />s-(III.G.1).
1 The Need for the Proposed Action: Because it is not possible to. predict the-specific conditions under which fire may. occur and propagate, the design basis protective features are specific in the rule rather than the design basis fire. l 8711130324 871027 DR ADOCK 0 % y4

.j . . - c p
2-Plant-specific features may require protection different from the measures specified in Sections III.G. In such cases, the licensee must demonstrate, by means of a detailed fire hazards analysis, that existing protection in. i conjunction with proposed modifications will provide a level of safety- j equivalent to the technical requirements of Se'ction III,G of Appendix R. l i
Environmental Impacts of the Proposed Action: The proposed exemptions provide 3
a level of safety equivalent to the technical requirements of Section III.G of 1 1
Appendix R. These exemptions will. not change the types, or allow an increase )
in the amounts, of effluents that may be released offsite. Furthermore, these .
exemptions will not result in an increase in individual or cumulative occupational radiation exposure. Therefore, the Comission' concludes that there are no significant radiological environmental impacts associated with the proposed Appendix R exemptions. I With regard to potential nonradiological impacts, the proposed I exemptions involve features located entirely within the restricted areas as defined in 10 CFR 20. They do not affect nonradiological: plant effluents and have no.Other environmental impact. Therefore, the Comission concludes that there are no significant nonradiological environmental. impacts associated with the proposed Appendix R exemptions.
Alternative Use of Resources: 'This action involves no use of resources not.
previously considered in the Final Environmental Statement (construction permit and operating license) for the Trojan Nuclear Plant.
Agencies and Persons Consulted: The NRC staff reviewed the licensee's request and did not consult other agencies or persons.

FINDING OF K0 51GNIFICANT IMPACT 4
. }
The Commission has determined not to prepare an environmental impact statement for the proposed Appendix R exemptions.
Based on the foregoing environmental. assessment of the proposed l
exemptions relative to the requirements of Appendix R to 10 CFR 50, the -l Comission concludes that the proposed action will not have a significant effect on the quality of the human environment. j For further details with respect to this action see' the letters l requesting exemptions from Appendix R of 10 CFR Part 50,' dated July 31, 1984, l
l May 31, 1985, October 16, and November 17, 1986, and May 8,1987, which are available for public inspection at the Commission's Public Document-Room, 1717 H Street, N.
