SUBJECT:
Virgil C. Summer Nuclear Station Docket No. 50/395 Operating License No. NPF-12 July 22, 198 3, Letter Addressing Technical Specification Surveillance Requirement Change
Dear Mr. Denton:
In a letter dated July 22, 1983, South Carolina-Electric and Gas Company (SCE&G) requested that items (b) and (c) of Technical Specification Surveillance Requirement 4.7.4,
" Service Water System," be transferred to Surveillance Requirement 4.6.2.3, item (b), " Reactor Building Cooling System."
Subsequent discussions with the Nuclear Regulatory Commission (NRC) staff indicated that further clarification is needed concerning valves in the Service Water System
-which receive a Safety Injection (SI) or an Engineered Safety Features Loading Sequence.(ESFLS) signal, other than those associated with the Reactor Building Cooling Units.
Our review indicates that the only automatic valves servicing safety related equipment in the Service Water System, which receive either a direct SI or ESFLS signal, are those associated with the Reactor Building Cooling Units.
Specifically, the following valves are tested:
TRAIN "A"
MVG-3103A Reactor Building Cooling Unit lA/2A Outlet Header Isolation MVG-3106A Service Water Booster Pump A Discharge MVG-3107A Reactor Building Cooling Unit lA/2A Return to Service Water Pond MVG-3108A Reactor Building Cooling Unit lA Inlet Isolation MVG-3108B Reactor Building Cooling Unit 2A Inlet Isolation MVG-3109A Reactor Building Cooling Unit lA Outlet Isolation MVG-3109B Reactor Building Cooling Unit 2A Outlet Isolation MVG-3110A Industrial Cooling to Reactor Building Cooling Unit lA/2A MVG-3111A Reactor Building Cooling Unit lA/2A to Industrial Cooling MVG-3112B Reactor Building Cooling Unit lA/2A to Industrial Cooling PVT-3164 Service Water to Digital Rod Position Indication Cooling Unit Coil Isolation g gdl
