I APPENDIX A Notice of Violation Duquesne Light Company Docket No. 50-412 Beaver Valley Power Station, Unit 2 License No. NPF-73 As a result of the inspection conducted on February 16 - March 31, 1989, and in accordance with the " General Statement of Policy and Procedures for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the following violation was identified:

10 CFR Part 50, Appendix B, Criterion V (" Instructions, Procedures and Drawings") requires that activities affecting quality shall be prescribed by documented instructions, procedures or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures or drawings.

Contrary to the above, on March 22, 1989, an inadvertent safety injection occurred due to several procedural inadequacies in that procedures were not appropriate for the circumstances since they did not prevent or ade-quately address the following:

1. Maintenance Surveillance Test Procedures did not prevent taking a second pressurizer pressure channel out of service before the first channel was restored to normal, resulting in the safety injection signal.

2. Activities associated <ith taking a pressurizer pressure channel out of service for a 24-hour period were not specified by the associated maintenance surveillance procedures.

3. Operations Surveillance Test No. 2.11.15, " Safety Injection Accumu-lator Check Valve Test," cid not prevent nor address enabling of all three accumulator stop valves at the same time. Such a configuration could have resulted in overfilling the pressurizer and spilling the potentially contaminated water into containment during the March 22,1989 safety injection.

This is a Severity Level IV Violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, Duquesne Light 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.
