SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NOS. 83 AND 70 TO FACILITY OPERATING LICENSE NOS. NPF-4 AND NPF-7 VIRGINIA ELECTRIC AND POWER COMPANY OLD DOMINION ELECTRIC COOPERATIVE NORTH ANNA POWER STATION, UNITS NO. 1 AND NO. 2 DOCKET NOS. 50-338 AND 50-339

Introduction:==
By letter dated December 19, 1985, the Virginia Electric and Power Company (the licensee) proposed changes to the Technical Specifications (TS) for the North Anna Power Station, Unit Nos. I and 2 (NA-182). Specifically, the proposed changes would revise the NA-1 TS which address Emergency Diesel Generators (EDG) by reducing the number of fast cold starts and reducing the number of tests that apply to both routine surveillance and special tests. The proposed changes to the recently issued NA-2 TS for EDG would correct typographical errors and remove an inconsistency in the use of a diffned term.
Discussion:
The proposed changes for the NA-1 TS for EDG are consistent with the recommendations provided in the Commission's Generic Letter 84-15. " Proposed Staff Actions to Improve and Maintain Diesel Generator Reliability," dated July 2, 1984. The proposed changes would make the NA-1 TS identical to the already approved TS for NA-2 which addressed EDG reliability and was consistent with Generic Letter 84-15. The SER for NA-2 which addressed EDG reliability was issued on April 25, 1985, and provides the safety basis for accepting the proposed changes for NA-1 since the NA-182 EDGs are identical.
Evaluation:
The staff has reviewed the proposed changes to NA-1 TS Sections 3.8.1.1, 4.8.1.1.1, 4.8.1.1.2, 4.8.1.2 and Table 4.8-2 and finds the proposed changes to be consistent with Generic Letter 84-15 as well as TS changes accepted by the staff for NA-2.
In addition, the staff has reviewed the proposed changes to NA-2 TS and finds these administrative change to be acceptable.
Environmental Consideration TLase amendments involve a change in the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase

. 4 in individual or cumulative occupational radiation exposure.. The Commission has previously published a proposed finding that these amendments involve no significant hazards consideration and there has been no public comment on such finding. Accordingly, these amendments meet the eligibility criteria for categorical exclusion set ferth in 10 CFR 551.22(c)(9). Pursuant to 10 CFR 951.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of these amendments.
Conclusion We have concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
