- APPENDIX A NOTICE OF VIOLATION Vermont 2 ankee Nuclear Power Corporation Docket No. 50-271

[

Vermont Yankee Nuclear Power Station License Mo DPR-28 During a routine NRC ir spection conducted on August 13 - October 9,1990, violations of NRC requirements were ider tined. In accordance with the " General Statement of Policy and

, Procedure for NRC Enf arcement Actions," 10 CFR Part 2, Appendix C (1990), the violations are listed below.

A. Technical Specinaation Section 6.5, Plant Operating Procedures, requires that detailed written procedures involving both nuclear and non-nuclear safety, covering operation of systems and components of the facility including applicable check-off lists and instructions shall be prepared, approved, and adhered to. Operating Procedure OP 2184, Fuel Pool Cooling System, requires that from and after the date that one of the fuel pool j cooling subsystems is made or found inoperable (and the remaining subsystem is capable of maintaining the fuel pool temperature below 150 degrees F) then the reactor shall be

_ in cold shutdown within thirty days unless such subsystem is sooner made operable.

Contrary to the above, between August 4,1989 and July 3,1990 the reactor was not placed in a cold shutdown condition, when the " A" fuel pool cooling subsystem remained inoperable for more than thirty days with the " A" fuel pool cooling pump power supply breaker, P9-1 A white tagged (Danger Tagged) in the open position.

This is a Severi y Level IV Violation (Supplement I).

B. 10 CFR 50, Appendix B, Criterion XVI, requires that conditions adverse to quality, such i as defective equament and nonconformances be promptly identified and corrected.

Additionally,10 CFR 50.49(f) requires that electrical equipment important to safety be qualified, in part, by testing or by analysis in combination with partial type test data. As stated in the licensee s Environmental Qualincation Program Manual, the " A" Spent Fuel Pool cooling pump motor is environmentally qualified (electrical) equipment important

_ to safety.

Contrary to the above, the "A" Spent Fuel Pool cooling pump motor was not qualified, due to a lack of testing or analysis in the degraded condition. Between June 9,1989 and 2 July 27,1990, the pump motor was in a degraded condition in that at least one phase of the motor winding shorted to ground following a brief period of operation. This condition adverse to quality represents a nonconformance that was not promptly identined and corrected.

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