VOLUNTARY ENTRY INTO TECHNICAL SPECIFICATION 3.0.1 FOR SURVEILLANCE TESTING OF NON-ESSENTIAL SERVICE WATER ISOLATION ACTUATION LOGIC 92-550 R2 50-280 50-281 DPR-32 DPR-37 Operability and surveillance requirements for the non-essential service water isolation function were incorporated into Table 3.7-2, "Engineered Safeguards Action Instrument Operating Conditions" of the Technical Specifications for Surry Units 1 and 2 by Amendment Number 130, dated June 19, 1989.
Included with the operability requirements was a permissible bypass condition, which allowed blocking of an actuation logic channel for up to two hours to perform the required surveillance testing.
Subsequently, Technical Specification Amendment Numbers 165/164, dated December 31, 1991, revised and reformatted Table 3.7-2 in its entirety. However, the permissible bypass condition was inadvertently omitted. Without the permissible bypass condition included in the Technical Specifications, the required surveillance testing cannot be performed within the existing Technical Specification requirements without entry into Technical Specification 3.0.1 or tripping both units.
In an August 14, 1992 telephone conference call between Virginia Power and the NRC, we identified the need to voluntarily enter into Technical Specification 3.0.1 to complete the required surveillance testing of the non-essential service water isolation actuation logic. Entry into Technical Specification 3.0.1 would be limited to two hours for each train to perform the required monthly surveillance testing and, if required, to perform maintenance related testing. The testing normally takes approximately 15 minutes to complete for each train. Additional voluntary entries into 3.0.1 will be performed monthly to complete the Technical Specification required testing on both channels until a Technical Specification amendment can be processed by both Virginia Power and the NRC to reinstate the permissible bypass condition. It is our intention to submit this Technical Specification in a timely fashion.

e Altha.ugh Technical Specification 3.0.1 will be entered, preparation and actions
, necessary for shutdown will not be initiated during these tests. However, should any unexpected conditions or delay occur, the provisions of Technical Specification 3.0.1 will be fully met.
Because these entries into Technical Specification 3.0.1 are voluntary and do not involve inoperable safety equipment, the entries will not be reported under 10 CFR 50.73.
If you have any additional questions, please call us.
Very truly yours,
