REQUEST FOR ADDITIONAL INFORMATION REGARDING VALVE RELIEF REQUEST 28. 30. 31. AND 32 PALISADES PLANT
!ST-PROGRAM SUBMITTALS DATED JUNE 3. 1997 AND JULY 24. 1997
- 1.
General For each Valve Relief Request (28, 30, 31, and 32), address the practicability of incorporating a performance review (of data in the plant and the Nuclear Plant Reliability Data System) into the testing procedure for the valves in question so that adjustments in the inspection or testing frequency and method can be made as needed.
- 2.
Valve Relief Request 28:
2.1 The basis for relief states that in order to test relief valve RV-2109, an alternate means of cooling the spent fuel pool would be required to isolate the spent fuel pool heat exchangers E-53A and E-538.
Provide details of the hardship.
involved in using "an alternate means. of cooling the Spent Fuel Pool."
2.2 Address the practicability of testing and repairing, as necessary, relief valves RV-0402, RV-0403, RV:-0954, RV-0955, and RV-2109 prior to entering potential overpressure conditions after the applicable heat exchanger is isolated.
2.3 Specify the maximum interval for setpoint testing.
- 3.
Valve Relief Requests 30 and 31:
The proposed alternative to relax the testing frequency for relief valves RV-0401, RV-3162, and RV-3164 could increase the likelihood and the extent of setpoint drift.
A stuck open residual heat removal system relief valve has occurred following a setpoint drift to that below system pressure at some plants in the past. An emergency procedure should be in place to mitigate the consequence of such a failure. When the shutdown cooling system is in service, the consequences of a stuck open relief valve (RV-0401, RV-3162, or RV-3164) could include a loss of shutdown cooling, requiring an alternative source of heat removal, or possibly a loss-of-coolant accident.
For each valve in question, please provide details of the consequences of such a failure during shutdown cooling, including descriptions of the emergency procedures in place to respond to the failure.
- 4.
Valve Relief Request Number 32:
For check valves CK-ES3216 and CH-ES3226, specify the maximum time for the
. disassembly and inspection interval and clarify the part-stroke exercise frequency of "quarterly each cold shutdown. n Enclosure
