':' The Inservice. Testing Program for pumps and valves is being revised based

m

' on Generic Letter 89-04 (documented in reference 1). The scope of the IST '

3 Program was also ' reviewed carefully to ensure the inclusion of the necessary

.; pumps and valves in the program. This was accomplished by using LaSa11e's ,

Q-List and Component Classification documents. The following is a short ~

} discussion of the program changes.

1. The field section for valves has been changed. " Technical-Approach (es) and Position (s)" was labeled No.10 and replaced the "masimum stroke time" field. The maximum stroke time will not be.a  ;

part of the NRC submittal due'to establishing limiting values of l

2. Added " disassemble and inspect"'(DI) an a new test type. f

3. Test abbreviation SA (semi-annual) has been added to the " test .
