. CHANGES TO CALLAWAY NUCLEAR PLANT INSERVICE TESTING PROGRAM Item 1:
Change:. 1 Revise Relief. Request P03:to add.flowtate testing to the Centrifugal Charging Pumps'en a Reactor Refueling frequency.
Basis for Change:.Per the NRR Safety Evaluation for the Callaway 4
IST Program, dated. August 19, 1987, Relief Request P03 was only granted interim relief until June 1, 1988.
See Relief Request for.
-justification of new revision.
. Item 2:
Change: Revise Relief Request.P09 to add flowrate testing to the Boric Acid Transfer Pumps on a Cold Shutdown frequency.
Basis for Change: Per the NRR Safety Evaluation for the Callaway IST Progtam, dated August 19, 1987 Relief
~ Request P09 was only granted interic relief until l
June 1, 1988.
Ses Relief Request for justification of new revision.
Etem 3:
Change:
Add Relief Request V06 to obttin relief from the requiremente of ASME Section XI IWV-3417(a) for power operated valves with a 2 secogid maximum allowable stroke time.
l Basis for Change: The corrective action requirement of IWV-3417(a) is ineffective in determining degradation ca valves that stroke rapidly.
See kelief Request V06.
Item 4:
Change: Decrease the maximum allowable stroke time from 15 seccnda to 10 seconds for EM-HV-8801A, B and EM-HV-8803A B.
[
Basis for Change: Re-evaluation of the valve functional requirements indicates that these valves need to stroke in 10 seconds rather than 15 seconds to i
meet design bases.
+
Item 5:
. Change: Add stroke time testing in the closed direction on a quarterly frequency for EM-HV-8871 and EM-HV-8964. Also add quarterly fail-safe testing and position indicatlon testing on a Reactor Refueling frequency.
Basi; for Changer The status of these valves has changed from passive to active due to change in plant normal 7
i operational valve line-up, i

Page 2 of 2 Item 6:
Change:
Increase the maximum allowable stroke time from 10 seconds to 20 seconds for AL-HV-5, 7, 9, 11.
Basis for Change: Valve maximum allowable stroke time was listed incorrectly.
Valve technical data shows a 20-second design maximum stroke time and is realistic as compared to actual stroke times.
Item 7:
Change:
Increase the maximum allowable stroke time from 3 seconds to 5 seconds for valves GT-HZ-4, 5, 11, 12 Basis for Change:
Technical Specification Amendment 33 increased the maximum allowable stroke time from 3 seconds to 5 seconds for these valves.
