APPENDIX A NOTICE OF VIOLATION Boston Edison Company Docket No. 50-293 Pilgrim Nuclear Power Station License No. DPR-35 As a result of the inspection conducted on August 3-7, 10-14 and 20, 1987, and in accordance with the the NRC Enforcement Policy (10 CFR 2, Appendix C) the following violation was identified:

10 CFR 50.49(e)(1) requires for safety related electrical equipment located in an harsh environment that the most severe design basis time dependent temperature be established and that the equipment be qualified for this most severe design basis temperature condition.

Contrary to the above as of August 20, 1987, the most severe design basis time dependent temperature had not been established for the following electrical equipment in the drywell: solenoid valve SV-220-44 and cable splice assemblies Q102A, Q102B, Q103A and Q103B.

It had been established only that the above devices were qualified for a large break Loss of Coolant Accident (LOCA) up to 290 F. This temperature was 30 F lower than the temperature profile for a small break LOCA to which drywell equipment would be subjected. Subsequent to the inspection, it was determined that these devices were actually qualified to the most severe temperature profile.

This is a Severity level IV violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, Boston Edison Company is hereby required to submit to this office within thirty days of the date of the letter which transmitted this Notice, a written statement or explanation in reply, including: (1) the corrective steps which have been taken and the results ,

achieved; (2) corrective steps which will be taken to avoid further violations; and (3) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending this response time, hk G
