2) ULNRC-3487 dated November 6, 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 I 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 l 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 GL 96-05.
