ENCLOSURE 1 NOTICE OF VIOLATION Virginia Electric and Power Company Docket No. 50-338 North Anna Unit 1 License No. NPF-4 During the Nuclear Regulatory Comn.ission (NRC) inspection conducted August 22 through September 25, 1989, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2. Appendix C (1989), the violation is listed below:

A.

Technical Specification 3.6.2.2 requires, in part, that the containment recirculation spray system be operable with four separate anc independent containment recirculation spray subsystems, each composed of a spray pump, associated heat exchanger and flow path. Allowance is given by the action statement for one containment recirculation spray subsystem to be inoperable for up to 7 days or be in hot standby within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

Contrary to the above, on August 26, the licensee rendered two containment recirculation subsystems inoperable for 47 minutes. This occurred due to the licensee's failure to correctly follow procedure 1-0P-49.6, Adjusting RSHX Isolatior. MOVs to Reduce Service Water Inleakage. The service water header "A" isolation valves,1-SW-MOV-101A and B, were tagged closed and de-energized at the same time with the associated cross-tie between the "A"

and "B" service water supply headers also isolated. This resulted in two of the four containment recirculation spray subsystems being inoperable.
