s RESPONSE TO NOTICE OF VIOLATION INSPECTION REPORT NOS. 50-280/84-20 AND 50-281/84-20 The following violations were identified during an inspection conducted on June 3-30, 1984. The Severity Levels were assigned in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C).
Technical Specification 6.4.A 7 requires that detailed written procedures with appropriate check-off lists and instructions shall be provided for preventative or corrective maintenance operations on safety related equipment.
Contrary to the above requirement, the corrective maintenance procedure (electrical) for safety related motor operated valves, EMP-C-MOV-50,
" Torque Switch Adjustments", did not contain appropriate instructions for setting or adjusting the Limitorque (SME-000) double torque switch on the Unit 1 and 2 service water (SW) motor operated valves SW-MOV-103A through D and SW-MOV-203A through D, which supply water to the recirc'ulation spray heat exchangers during accident conditions.
EMP-C-MOV-50 did not provide instructions for mid-positioning or manually declutching the MOV before setting or adjusting the torque switches, which apparently resulted in the incorrect torque switch settings on SW-MOV-203D observed by the inspector on June 5, 1984.
This is a Severity Level IV violation (Supplement I), and applies to both units.
VEPCO RESPONSE:
(1) ADMISSION OF THE ALLEGED VIOLATIONS:
The violation is correct as stated.
(2) THE REASON FOR THE VIOLATION:
Certain models of Limitorque torque switches require that the associated valve be in a relaxed position during the setting of the torque switch. This requirement was not specified in the procedures for torque switch settings on the subject valves because it was not specified in the manufacturer's technical manual.
(3) THE CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED:
Corrective Maintenance Procedure EMP-C-MOV-50 was revised to give adequate instructions for setting or adjusting Limitorque torque switches.
In addition, Surry Power Station has implemented a program to verif7 proper torque switch settings on all safety-related M0V's.
l (4) THE CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS:
All torque switch settings on safety-related MOV's will be verified, and the settings or adjustments will be made in accordance with the approved procedure.
I Attcchment to Lsttar Nat 472
.(5) THE DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED:
Corrective Maintenance _ Procedure EMP-C-MOV-50 was revised on June 14, 1984. The verification of proper torque switch settings on all safety-ralated MOV's has commenced and will be completed by November 23, 1984.
