Dear Mr. Denton:

AMENDMENT TO OPERATING LICENSES NPF-4 AND NPF-7 NORTil ANNA POWER STATION UNIT NOS.1 AND 2 PROPOSED TECHNICAL SPECIFICATION CHANGES Pursuant to 10 CFR 50.90, the Virginia Electric and Power Company hereby requests an amendment, in the form of changes to the Technical Specifications to Operating Licenses NPF-4 and NPF-7 for the North Anna Power Station, Unit Nos. 1 and 2. The proposed changes are enclosed and have been designated Change No. 35 for Unit 1 and Change No. 3 for Unit 2.

In a letter f rom Mr. D. G. Eisenhut dated April 10, 1980, we were requested to submit proposed changes to the Technical Specifications for North Anna Units No.1 and 2 which would clarify the meaning of the term OPERABLE as it applies to the single failure criterion for reactor safety systems. In accordance with the request, the enclosed proposed changes clarify the definition of operability in the North Anna Technical Specifications.

A new Limiting Condition for Operation and a corresponding Basis have been proposed for both Unit 1 and Unit 2. Proposed Specifica-tion 3.0.5 will clarify the interaction of the Limiting Conditions for Operation for a support system and the Limiting Condition for Operation for equipment, thereby enhancing the margin of safety by adding assurance that safety systems are available.

This request has been reviewed and approved by the Station Nuclear S-My and Operating Committee and the System Nuclear Safety and Operating Committee. It has been determined that this request does not involve an unreviewed safety question.

This request has been reviewed in accordance with the criteria in 10 CFR 170.22. Since this request is in response to NRC recommendations and simply provides additional clarification of the existing Technical Specifications, this request is administrative in nature; therefore, a Class II license amendment fee is required for Unit 1 and a Class I license THIS DOCUMENT CONTAINS 8005221624 P00R QUAUTY PAGES l
