UNITED STATES NUCLEAR REGULATORY COMMISSION CONNECTICUT YANKEE ATOMIC POWER COMPANY DOCKET N0. 50-213 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Connission (the Connission) is considering issuance of exemptions from the requirements of Appendix R to 10 CFR Part 50 to Connecticut Yankee Atomic Power Company (the licensee), for the Haddam Neck Plant located in Middlesex County, Connecticut.

ENVIRONMENTAL ASSESSMENT Identification of Proposed Action: The exemptions would grant relief in eight 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 exemptions would include specific areas of the Primary Auxiliary Building, Service Building, Switchgear Room, Turbine Building and the Control Room.

The exemptions are responsive to the licensee's application for exemptions dated September 16, 1985.

, The Need for the Proposed Action: The proposed exemptions are 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 method 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 exemptions will provide a degree of fire protection such that there is no increase in 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 determined, nor does the proposed exemption otherwise affect radiological plant effluents. Therefore, the Commission concludes that there are no significant radiological environmental impacts associated with this proposed exemption.

With regard to poter.tial non-radiological impacts, the proposed exemptions involve features located entirely within the restricted area as defined in 10 CFR Part 20. They do not affect non-radiological plant effluents and have no other environmental impact. Therefore, the Commission concludes that there are no significant non-radiological environmental impects associated with the proposed exemptions.

Alternative Use of Resources: This action does not involve use of resources not previously considered in the Final Environmental Statement for the Haddam Neck Plant.

Agencies and Persons Consulted: The NRC staff reviewed the licensee's 1

request and did not consult other agencies or persons.

l 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 assessment, we conclude that the proposed action will not have a significant effect on the quality of the human environment.

Dated at Bethesda, Maryland this 28th day of April 1986.
