APPENDIX A NOTICE OF VIOLATION Louisiana Power & Light Company (LP&L) Docket: 50-382 Waterford Steam Electric Station, Unit 3 (W-3) Operating License: NFF-38 During an NRC inspection conducted on March 27-31, 1989, a violation of NRC requirements was identified. The violation involved failure to provide adequate design controls. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1988),

the violation is listed below:

Inadequate Design Control Criterion III of Appendix B to 10 CFR Part 50 states, in part " Measures shall be established to assure that applicable regulatory requirements and

~

the design basis, as defined in 10 CFR 50.2 and as specified in the license application, for those structures, systems, and components to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions. . . . The design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of alternate or simplified calculational methods, or by the performance of a suitable testing program. . . ." This is implemented by the licensee's approved Quality Assurance Plan.

l l Contrary to the above, the following examples of the failure to control l the facility design adequately were identified:

1. Containment sump recirculation valves' backup air supply accumulators were not designed or tested to ensure proper system operation for all conditions postulated by the design basis.

2. Static uninterruptible power Supply 3A-S was modified by the addition of a nonsafety-related load to the distribution panel without accounting for the effects of load faults on the inverter operation.

These examples are a Severity Level IV violation. (Supplements)(382/8911-01)
