SUBJECT:
ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT RE:
PILGRIM I, OPR-35 Reference (a) - Order for Modification of License Concerning the Environmental Qualification of' Safety-Related Electrical Equipment dated October 24, 1980
Dear Mr. Morisi:
This letter transmits the Safety Evt.luation for the Environmental Qualification of Safety-Related Electrical Equipment at your facility. This evaluation was
-based on your submittals dated March 12, April 18 and 22, July 22, October 29, 1980 and April 13, 1981. Our letter of March 30, 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 I
comply with Reference (a). We request that you provide the information identi-fied in sections 3 and 4 of this Safety Evaluation to us within 90 days.
This Safety Evaluation addresses only the safety-related electrical equipment exposed to a harsh environment resulting from an accident (i.e., the IEB 79-018 review). Reference (a) requires that all safety-related electrical equipment be qualified by June 30, 1982. The NRC review effort for the equipment in mild environments will be addressed by separate correspondence, i
.Your response may present alternatives to the staff positions in the evaluation.
The staff will consider alternative approaches if these methods are within the D0R Guidelines or NUREG-0588,'as appropriate. For example, an acceptable 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 analysis, together with reference to the previous NRC acceptance of that analysis, accompanies the 90 day response.
In addition, some of the information in the Safety Evaluation may require clarification. Contact your project manager for assistance in these 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, i
