United States Nuclear Regulatory Commission Attention:
Mr. Vincent S. Noonan Page 2 8.
Operability Qualification of Pumps and Valves (PVORT) Items 1.
Section 3.10.2.3(2): This section concerns the cracked seal on auxiliary feedwater pump (FW-P-37A) and states the pump must be retested prior to fuel load to verify seal integrity'.
Response
Letter SBN-997 ( April 8,1986), Attachment A, Item 8(a), explained that the shaft seal was remachined to correct the mismatch of the shaft and seal. The retest of.the pump cannot be done prior to fuel load because the only steam supply to the pump is from the secondary side of the plant. The test will be conducted in conjunction with the startup test program, af ter core-load, but prior to initial criticality. The schedule for the retest has been discussed with Region I inspectors and found acceptable.
2.
Section 3.10.2.3(3):
This item is to confirm that the AUXILIARY FEEDWATER PUMP (FW-P-37A) turbine trip and throttle valve can be operated easily during an emergency condition.
Response
Letter SBN-1025 (May 1,1986) provides the results of tests which show that one man can operate the valve following an overspeed trip.
We expect that the program to reconcile generic g-loading of NSSS valves (SER Section 3.10.1.3), and the overall completion of the seismic qualification program (SER Section 3.10.2.3(5)], to be completed by June 30,1986. The NRC will be notified when these programs are complete..
We trust this information is acceptable and request the status of these items be reflected in the next supplement to Seabrook's SER.
Very truly yours, A
