SUBJECT:

ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT RE: MILLSTONE NUCLEAR POWER STATION, UNIT NO. 2 - DPR-65 Reference (a) - Order for Modification of License Concerning the Environmental Qualification of Safety-Related Electrical Equipment dated October 24, 1980.

Dear Mr. Counsil:

This letter transmits the Safety Evaluation for the Environmental Qualification of Safety-Related Electrical Equipment at your facility. This evaluation was based on your submittal dated October 31, 1980. Our letter of April 14, 1981, which forwarded our preliminary results, indicated that an item-by-item re-evaluation would be required at a later date. This safety evaluation identifies the specific information required by the staff and the actions, on your part, necessary to comply with Reference (a). We request that you provide the information identified in sections 3 and4 of this Safety Evaluation to us within 90 days. We are aware that some additional information has been provided in your letters of January 30 and April 30, 1981. We will evaluate this additional information along with your 90 day response.

f This safety evaluation addresses only the safety-related electrical equipment l

exposed to a harsh environment resulting from an accident (i.e., the IE Bulletin l

79-01B review). Reference (a) requires that all safety-related electrical l

equipment be qualified by June 30, 1982. The NRC review effort for the l

equipment in mild environments will be addressed by separate correspondence.

Your response may present alternatives to the staff positions in the evaluation.

l The staff will consider alternative approaches if these methods are within the D0R Guidelines or NUREG-0588, as appropriate. For example, an acceptable l

alternative to the NRC staff's temperature criterion used for the service conditions (i.e. Section 3.3) must base that service condition on the FSAR analysis or other NRC approved analysis, provided that the specific analysts, together with reference to the previous NRC acceptance of that analysis, i

accompanie? the 90 day response.

In addition, some of the information in the Safety Eval stion may require clarification. Contact your project manager for assistance in ti.ae matters.

)

2-It remains your responsibility to assure that the qualification deadline is met for all safety-related electrical equipment. The staff's review of your response to this letter should not delay any action which is required in order to meet the deadline.

Sincerely, C&i/

Robert A. Clark, Chief Operating Reactors Branch #3 Division of Licensing
