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 1 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 a

response to GL 96-05. Therefore, although the staff considered your MOV gg b 9612040262 961129 PDR ADOCK 05000483 P PDR
