APPENDIX A NOTICE OF VIOLATION Southern California Edison Company Docket No. 50-362 San Onofre Unit 3 License No. NPF-15 As a result of the inspection conducted during the period of July 18 through August 5, 1988, and in accordance with the NRC enforcement policy, 10 CFR Part 2, Appendix C (1988), the following violation was identified:

Technical Specification 6.0.1.c requires that written procedures be established, implemented and maintained covering surveillance and test activities of safety related equipment.

Engineering Procedure 503-V-3.12, Temporary Change Notice (TCN) 1-1, specified containment integrated leakage rate test requirements. In particular, step 2.1 of attachment 5 of the procedure required that:

.aution tags shall be completed and placed on the valves, identified below, during the test valve lineup. (See section 4.0 and 5.0 of this attachment)." Valves, 3 LV-0110 A and B were in the lineup and were to j remain closed. '

Contrary to the above, while performing the containment integrated leakage rate test (ILRT) during the period between July 18 through July 21, 1988, j caution tags were not placed on valves 3 LV-0110 A and B. As a result, valve 3 LV-0110A was opened to allow maintenance unrelated to the ILRT, which in turn permitted an uncontrolled loss of approximately 250 gallons of water from the Shutdown Cooling System.

This is a Severity Level IV violation applicable to Unit 3 (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, Southern California Edison Company is hereby required to submit a written statement or explanation to the U.S.
