e ENCLOSURE 1 NOTICE OF VIOLATION Virginia Electric and Power Company Docket No. 50-281 Surry License No. DPR-37

'During the Nuclear Reg'ulatory Commission (NRC) inspection conducted on November 13 - 20, 1986 and February 9, 1987, a violation of NRC requirements was identified. The violation involved failure to properly establish conditions.to perform the Type A ILRT. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986), the violation is listed below:

10 CFR 50 Appendix J Paragraph II defines a Type A test as a test intended to measure the primary containment overall integrated leakage rate obtained by a summation of leakage through all potential leakage paths including valves, fittings, and components which penetrate containment.

Paragraph III.A.1.(d) requires that fluid systems that are part of the reactor coolant pressure boundary and are open directly to the containment atmosphere under post-accident conditions shall be opened or vented to the containment atmosphere prior to and during the Type A test. All vented systems must be drained of water to the extent necessary to assure exposure of the containment isolation valve to containment air test pressure and to assure they will be subjected to the post-accident. differential pressure.

Systems that are normally filled with water and operating under post-accident conditions are not required to be vented; however, their contain-ment isolation valves must be Type C tested.

Paragraph III.C requires that containment isolation-valves be Type C tested

, to~ measure their leakage rate by pressurizing with air or nitrogen unless the valve is pressurized with fluid from a seal system.

Technical Specification, Table 3.8-2, lists the containment isolation valves i' and specifies which ones are exempt from Type C testing. Such exemption signifies that the valves have received credit for a water seal and are not

. considered a credible leakage path for the containment atmosphere.

Table 3.8-2 includes the isolation valves for Penetrations No. 46, 63, 64, and 66 through 71 and does not exempt them from Type C testing.

i. Contrary to the above the licensee failed to either properly vent and drain l

Penetrations No. 46, 63, 64, and 66 through 71 during the performance of the November 1986, Type A test on Unit 2, or to determine the overall integrated

! leakage rate by the summation of the leakages obtained during the Type C testing of such penetrations to the results obtained during the CILRT.

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