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 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 3

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

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
