I ENCLOSURE 1 NOTICE OF VIOLATION Entergy Operations, Inc. Docket No.: 50-382 Waterford Steam Electric Station, Unit 3 License No.: NPF-38 l During an NRC inspection conducted on October 21-25,1996, two violations of NRC requirements were identified in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed below:

A. 10 CFR Part 50, Appendix 8, Criterion XVI, requires, in part, that conditions adverse to quality be promptly identified and corrected.

Procedure OP-901-511," Instrument Air Malfunction," Attachment 5, Note 1, required that accumulators for Valves CC-135A(B), Dry Cooling Tower A(B) inlet isolation valve, have pre-staged motive cylinders (nitrogen bottle) to allow a backup air source to be connected to the accumulators on a loss of instrument air.

Contrary to the above, conditions adverse to quality were not promptly identified and corrected in that:

1. As of October 22,1996, the licensee failed to determine all of the potential water usage sources from the condensate storage pool following a design basis tornado event, as required by Condition Report 96-0086, dated l January 22,1996.

2. From October 14-21,1996, the licensee did not implement immediate corrective actions specified in Condition Report 96-1630 by prestaging a nitrogen cylinder for Valve CC-135B, as required in Procedure OP-901-511.

This is a Severity Level IV violation (Supplement 1) (50-382/9624-01).

! i B. 10 CFR 50.55a(g) requires, in part, that inservice testing to verify operational readiness of pumps and valves whose function is required for safety be accomplished in accordance with Section XI of the ASME Boiler and Pressure i Vessel Code.

l Section XI, " Rules for Inservice inspection of Nuclear Power Plant Components," i Subsection IWV-1100, includes within the scope of inservice testing, Class 1,2,  ;

and 3 valves (and their actuating and position indicating systems), that are required to perform a specific function in shutting down the reactor or in mitigating the consequences of an accident.

Contrary to the above, as of October 22,1996, the licensee failed to verify the operational readiness of valves whose function is required for safety in accordance with Section XI of the ASME Boiler and Pressure Vessel Code. Specifically, the

! licensee failed to perform testing that ensured operational readiness of the j safety-related air accumulators of ASME Class 3 valves.

This is a Severity Level IV violation (Supplement I) (50-382/9624-02).
