Subject:

Vermont Yankee 60-day Response to Generic Letter 96-05 i >

I l

In Reference (b), the NRC requested licensees to establish a program, or ensure the effectiveness l of the current program, to verify on a periodic basis that safety-related MOVs continue to be

- capable of performing their safety functions within the current licensing bases of their facilities. 1 The NRC noted that the program should ensure that changes in required performance resulting l l from degradation (such as those caused by_ age) can be properly identified and accountea for.

] Licensees that have developed periodic verification programs in response to GL 89-10 should i

review those programs to determine whether any changes are appropriate in light of the i

information in Reference (b).

1 4

The NRC requested that licensees submit a report within 60 days of the date of this Generic Letter indicating whether or not they will implement the requested actions and the schedule for completing implementation. The purpose of this letter is to provide the information requested.

By December 31,1997 Vermont Yankee will have established its motor-operated valve periodic verification program. At that time, the program and its implementing procedures and guidelines will be in place. This date was chosen in consideration of activities to be performed prior to program initiation. These activities include: (1) establishment of relative safety risk and force

' margins, (2) assignment of appropriate inservice tests (IST) and test frequencies, (3) development 3

- of any new test equipment or testing techniques; and (4) submittal of an application to use the - i periodic verification program as an alternative to existing IST stroke-time testing requirements as discussed in Reference (b).

We' trust that the information provided is acceptable. However, should you have questions or require additionalinformation, please contact this office.
