, ENCLOSURE 1 NOTICE OF VIOLATION I

Virginia Electric and Power Company Docket Nos. 50-338 and 50-339 North Anna License Nos. NPF-4 and NPF-7 During the Nuclear Regulatory Commission (NRC) inspection conducted on April 12-14 and April 20-26, 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.

10 CFR 50, Appendix J, Paragraph III.C.1 states that Type C tests shall be performed by local pressurization. The pressure shall be applied in the same direction as that when the valve would be required to perform its safety function, unless it can be determined that the results from the test for a pressura applied in a different direction will provide equivalent or more conservative results.

Contrary to the above, two examples of non-conservative Type C testing of containment isolation valves were identified as follows:

a. During the Unit 1 1987 refueling outage, six gate valves and seven globe valves or Unit I and, previous to the Unit 2 outage later that same year, fif teen valves on Unit 2 had been tested by not applying pressure in the same direction as that when the valves would be required to perform their safety function. The licensee has taken corrective action for this issue; consequently, a response is not required,

b. Twenty-four globe valves in each unit, identified in the Licensee's Engineering Study 88-31 dated November 10, 1988, are Type C tested by l applying test pressure in a direction different than the accident pressure and which tends to seat the valves. The NRC review has concluded that this test is not equivalent or more conservative than applying test pressure in the accident direction which would tend to unseat the valves.

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

Pursuant to the provisions of 10 CFR 2.201, Virginia Electric and Power Ccapany is hereby required to submit a written statement or explanation to the Nuclear l Regulatory Commissicn, ATTN: Document Control Desk, Kashington, DC 20555, with a copy to the Regional Administrator, Region II, and a copy to the NRC Resident Inspector, within 30 days of the date of the letter transmitting this Notice. Regarding example a of the violation, the inspector has reviewed your corrective action and no response is raquired. For example b of the i violation, a response is necessary. This reply should be clearly marked as a Q72so229ggoy,,

" Reply to a Notice of Violation" and should include: (1) admission or denial of the violation, (2) the reason for the violation if admitted, (3) the corrective steps which have been taken and the results achieved, (4)the corrective steps which will be taken to avoid further violations, and (5) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending the response time. If an adequate reply is not received within the time specified in this Notice, an order may be issued to show cause why the license should not be modified, suspended, or revoked or why such other action as may be proper should not be taken.

FOR THE NUCLEAR REGULATORY COMMISSION Mr Mu Caudie A. Julian, Chief Engineering Branch Division of Reactor Safety Dated at, Atlanta, Georgia thig 4ay of July 1989 I
