NORTHEAST NUCLEAR ENERGY COMPANY DOCKET NO. 50-245 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of an exemption from the requirements of Appendix R to 10 CFR Part 50 to Northeast Nuclear Energy Company, et al. (the licensee), for the

• Millstone Nuclear Power Station, Unit No. 1, located in New London County, Connecticut.

ENVIPONMENTAL ASSESSMENT +

Identification of Proposed Action: The exemption would grant relief in ,

five fire areas to the extent that redundant safe shutdown related cable and equipment are not separated and/or protected in accordance with Section III.'G.2 of Appendix R. The five fire areas are as follows: Main Control Room, Turbine Building Reactor Feed Pump, Turbine Building Switchgear Area T-19A and T-19CDE, and Reactor Building Northeast.

The exemptions are responsive to the licensee's applications for exemptions dated March 1,1982, July 16,1982; April 15,1983; December 4, 1984;' and August 7 and 23, 1985.

., The Need for the Proposed Action: The proposed exemption is needed because the features described in the licensee's requests regarding the existing and proposed fire protection at the plant for these items are the most practical nethnd for meeting the intent of Appendix R and literal compliance would not significantly enhance the fire protection capability.

Environmental Impacts of the Proposed Action: The proposed exemption will provide a degree o# fire protection such that there is no increase ir the risk of fires at this facility. Consequently, the probability of fires has not been increased and the post-fire radiological releases will not be

greater than previously detennined nor does the proposed exemption otherwise affect radiological plant effluents. Therefore, the Comission concludes that there are no significant radiological environmental impacts associeted with this proposed exemption.

With regard to potential nonradiological impacts, the proposed exemptions involve features located entirely within the restricted area as defined in 10 CFR Part 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 exemptions.

Alternative llse of Resources,: This action involves no use of resources not previously considered in the Final Environmental Statements for the Millstone Nuclear Power Station, l' nit No. 1.

Agencies and Persons Consulted: The NRC staff reviewed the licensee's request and did not consult other agencies or persons.

FINDING OF NO SIGNIFICANT IMPACT

, The Commission has determined not to prepare an environmental impact statement for the proposed exemptions.

Based upon the foregoing environmental assessnent, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
