Generic Letter 96-05 reque:;ted that addressees establish a program, or ensure the effectiveness of their current program, to verify on a periodic basis that safety-related MOV's continue to be capable of performing their safety functions within the current licensing basis of the facility. The program should ensure that changes in i
required performance resulting from degradation (such as those caused by age) can be properly identified and accounted for. The NRC requested that all 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 GL 96-05.
The status of the requested actions at Maine Yankee, consistent with the preuntation of the required responses, j
are as follows:
NRC Required Response (1):
Within 60 days of the date of this generic letter, a written response indicating whether or not the addressee will implement the actions requested above. If the addressee intends to implement the requested actions, submit a schedule for completing implementation. If an addressee chooses not to take the requested actions, submit a description of any proposed attemative course of action, the schedule for completing the attemative' course of action (if applicable), and the safety basis for determining the acceptability of the planned alternative course of action.
Maine Yankee Response:
Maine Yankee will implement the requested actions by conducting a review consistent with the generic letter of it's GL 89-10 Periodic Verification Program, and it's appropriate surveillance procedures. The program l
review, and any subsequent actions necessitated by the review, will verify the effectiveness of Maine Yankee's Periodic Verification program of our safety related MOV's design basis capability. Specifically, Maine Yankee l
will ensure it's program meets tce attributes discussed in Attachment 1 of GL 96-05, with consideration for:
- 1) risk insights to assist in determining valve tests and test frequency,2) providing adequate confidence that program MOV's remain operable until their next test,3) valve importance and the benefits and potential adverse affects in determining the type of testing,4) including all GL 89-10 program MOV's, and all safety related MOV's assumed to be capable of retuming to their safety position when placed in a position that prevents their safety system (or train) from performing it's safety function; and the system (or train) is not declared inoperable when the MOVs are in their non safety position, 5) evaluating and monitoring valve performance and
,O maintenance and periodically adjusting the periodic verification program as appropriate. Our intention at this time is to complete these actions prior to startup from our next refueling outage, approximately the fourth quarter of 1997.
