(GL) 96-05, " Periodic Verification of Design-Basis i Capability of Safety-Rehted Motor-Onerated Valves"

Dear Madam or Sir:

This letter is responding to GL 96-05. GL 96-05 requires that addressees 3 establish a program, or to ensure the effectiveness of its current program, to verify on a l periodic basis that safety-related Motor-Operated Valves (MOVs) continue to be capable of performing their safety functions within the current licensing bases of the facility. The program should ensure that changes in required performance resulting from degradation (such as those caused by age) can be properly identified and accounted for. In addition, addressees that have developed periodic verification programs in response to GL 89-10 should review those programs to determine whether ,

any changes are appropriate in light of the information in this generic letter.  !

Addressees are required to respond with the following information within sixty days from the date of this generic letter.

la) Indicating whether or not the addressee will implement the action (s) requested herein.

In accordance with the recommendations of Generic Letter 89-10, Clinton Power Station (CPS) established and implemented an MOV Periodic Verification Program. This program is designed to ensure that the long term i performance capability of GL 89-10 MOVs is maintained. This program incorporates an appropriate mix of diagnostic testing in conjunction with a comprehensive trending program. It is the intent that this combination of diagnostic testing and trending program will be sufficient to detect potential degradations which could possibly result in increased thrust / torque requirements or decreases in actuator output.
