S. Nuclear Regulatory Commission 101 Marietta Street, Suite 2900 Atlanta, Georgia 30323 Docket Nos.
50-280 50-281 License Nos. DPR-32 DPR-37
Dear Dr. Grace:
VIRGINIA POWER SURRY POWER STATION INSPECTION REPORT NOS. 50-280/84-20 and 50-281/84-20 On July 27, 1984, NRC issued Report Nos. 50-280/84-20 and 50-281/84-20 which contained a Notice of Violation.
Virginia Power responded with letter Serial No. 472 dated August 24, 1984.
This response stated, in
- part, th~t verification of proper torque switch settings on all safety-related motor operated valves (MOVs) would be completed by November 23, 1984.
The above date was chosen to conform to a scheduled Unit 1 refueling outage and a scheduled Unit 2 snubber/maintenance outage.
The Unit 1 outage occurred generally as scheduled and most of the MOVs were inspected. There are a total of 109 MOVs in this unit which use the SMB-00 or SMB-000 Torque Switch.
All but twenty-three were inspected of which fourteen were on safety-related MOVs.
These were:
MOV-CS-lOOB MOV-SW-102A MOV-SW-102B MOV-1275A MOV-1275B MOV-1275C MOV-1370 MOV-1863B MOV-1865A MOV-1865B MOV-1865C MOV-1867A MOV-1867B MOV-1869B B Containment Spray Pump Suction Service Water Supply to CC Heat Exchanger Service Water Supply to CC Heat Exchanger A Charging Pump Recirc to RWST B Charging Pump Recirc to RWST C Charging Pump Recirc to RWST RCP Seal Injection Alternate Suction to Charging Pump 11A 11 Accumulator Discharge 11B 11 Accumulator Discharge 11C 11 Accumulator Discharge Boron Injection Tank Inlet Boron Injection Tank Inlet Boron Injection Tank Bypass

PDR.
VIRGINIA POWER The remaining torque switches will be inspected during the spring snubber/maintenance outage scheduled to commence June 14, 1985.
Subsequent to our response, Virginia Power decided to request deferral of the Unit 2 outage in view of the impending (March 1985) refueling outage.
While this deferral request was being considered by the NRC, a Reactor Coolant Pump failure occurred, causing an unscheduled outage.
Torque switches were not inspected because of manpower limitations imposed by a dual unit outage.
Virginia Power plans to inspect the torque-switch settings on the safety-related MOVs in Unit 2 during the spring refueling outage. This inspection is scheduled to be completed by June 8, 1985.
