NPF-63 IN-SERVICE PUMP AND VALVETESTING PROGRAM NRC REQUEST FOR ADDITIONALINFORMATION Gentlemen:
SERIAL: NLS-87-052 8703250212 870320 PDR ADOCK 05000400 In response to an NRC staff request, Carolina Power etc Light Company (CPRL) herein submits additional information concerning the In-service Pump and Valve Testing (IST)
Pr ogram.
This information supplements the IST Program, Revision 3, submitted on September 16, 1986 and amended in our submittal of December 31, 1986.
The staff requests are reiterated below followed by CPRL's response.
Request:
Why can't the throttle and governor valves for the auxiliary feedwater turbine driven pump be fullstroke exercised?
Response
The throttle valve can and willbe full stroke exercised on a quarterly basis.
The governor valve is hydraulically operated, drawing the hydraulic fluid from the AFW pump.
The AFW pump must be running for the governor valve to operate.
The governor valve's controller senses steam line pressure and turbine speed and automatically adjusts over a limited travel range to maintain AFW pump speed constant.
Full stroking of the governor valve (independent of the speed control function) while the pump is running can lead to overspeed of the pump.
Request:
It is implied that 1CE-56 willbe full stroke exercised on the way to a cold shutdown.
A statement verifying this is needed.
Response
Full stroke exercising of this valve willbe performed on the way to a cold shutdown when the auxiliary feedwater turbine driven pump is being tested.
The procedure governing the IST program willbe modified to incorporate these within 30 days after the NRC's SER is issued to CPRL.
