- 1) NRC Generic Letter 96-05 dated September 18, 1996

- 3) NRC Letter from K. M. Thomas to D.
F.
Schnell dated November 29, 1996 Generic Letter 96-05 requested licensees to establish a program, or ensure the effectiveness of the current program, to verify on a periodic basis that i
safety-related motor-operated valves (MOVs) are capable of performing their safety functions within the current licensing bases of the facility.
GL 96-05 also required submittal of a written summary description of the MOV periodic verification program.
Our response (Reference 2) indicated that all actions requested by GL 96-05 were closed.
This conclusion was based on staff approval of the Callaway Plant GL 89-10 program, which includes a commitment to maintain a periodic verification program, and our involvement in industry activities.
However, because of subsequent activities within the industry and NRC to address long-term MOV performance, the staff, in Reference 3, requested additional information f
concerning any actions we will be taking in response to l

1.
completion of the MOV performance prediction program by the Electric Power Research Institute and NRC issuance of a safety evaluation on the j
EPRI program; 2.
preparation of a code case by the American Society of Mechanical Engineers on an MOV periodic verification program that could be used as an alternative to stroke-time testing; and 3.
tests sponsored by the NRC on the aging of valve material samples.
We will submit this supplemental information by the GL 96-05 180-day response date of March 17, 1997.
