Dear Mr Brown:
,1
SUBJECT:
RESPONSE TO GENERIC LETTER 89-10. " SAFETY-RELATED MOTOR-0PERATEDVALVE(MOV)TESTINGANDSURVEILLANCE" (TACNO.75715)
+
On June 28, 1989, the.NRC issued Generic Letter (GL) 89-10 requesting'the establishment of a program to ensure the operability of all safety-related motor-operated valves (h0Vs) under design-basis conditions. The program in.
'GL 89-10 significantly expands the scope of the program outlined in NRC Bulletin 85-03 and its supplement.
On January 2,1990, you submitted a response to GL 89-10 " Safety-Related
. Motor-Operated. Valve Testing and Surveillance,"~regarding Unit 1-of the SeabrooK Station. Several :omments on the submittal are provided below:
1 1...
The schedule provided in the generic letter requested that'a description of your:MOV= program be available f~ review by June 28, 1990, or the first refueling outage after Decemba SR 1989, whichever was later. Due to delays in.. issuing Supplement l' of t.lgeneric letter, the-staff has decided to delay inspections ~until at least January 1,'1991. Therefore, your program description need not be(available on site until January.1, 1991,'or the first refueling after December 28, 1989, whichever is later.
Information that should be contained in your program description was
-discussed during the workshops held in September 1989 and is provided in Supplement 1 to the generic letter. As your MOV' program is developed,
. justification for any differences between your program and the generic letter should be incorporated in your program description.
Your program
-description should be retained for possible further NRC review.
2.
In your response you indicated that a large number of MOVs in safety-related systems have undergone extensive baseline and differential pressure / flow
. testing.- Additionally, you indicated that additional differential pressure / flow testing may not be necessary. The primary basis for the staff's request that each safety-related MOV be tested under design-basis full flow and differential pressure conditions, where practicable, is that current extrapolation. techniques may not indicate the actual operating characteristics of a particular MOV.
