SUBJECT:
GENERIC LETTER 96-05, " PERIODIC VERIFICATION OF DESIGN-BASIS CAPABILITY Of CATETY-RELATED MOTOR-0PERATED VALVES" - CALLAWAY PLANT, UNIT I (TAC NO. M97027)
Dear Mr. Schnell:
By letter dated November 6,1996, Union Electric Company (UE) submitted its 60-daf response to Generic Letter (GL) 96-05, " Periodic Verification of
- Design-Basis Capability of Safety-Related Motor-0perated Valves," for the l
Callaway Plant, Unit 1.
In the response, UE indicated that based on previous staff review of the GL 89-10 program at Callaway, UE did not plan to implement the requested actions in GL 96-05 and considered all actions in GL 96-05 to be closed for the Callaway Plant.
l On June 8,1994, the NRC staff notified you that we had completed our review of your GL 89-10 program.
In that letter, we referred to your plans to l
perform periodic performance verification of your safety-related motor-operated valves (H0Vs) and to continue to monitor industry data to ensure that margin was available to compensate for potential degradation.
In the almost 2-1/2 years since the staff reviewed your GL 89-10 program, significant activities have been conducted by the industry and NRC to address long-term MOV performance. These activities include:
i l
1.
completion of the MOV performance prediction program by the Electric Power Research Institute and NRC issuance of a safety evaluation on the EPRI program; 2.
preparation of a code case by the American Society of Mechanical l
Engineers on an MOV periodic verification program that could be used as l
an alternative to stroke-time testing; and l
3.
tests sponsored by the NRC on the aging of valve material samples.
In light of this new information, the staff requested in GL 96-05 that licensees who have developed MOV periodic verification programs in response to GL 89-10, review those programs to determine whether any changes are appropriate. The staff has also learned that the utility owners' groups are considering an industry-wide effort in developing long-term MOV programs in response to GL 96-05. Therefore, although the staff considered your MOV a
