At 1543 on 11/2/82Zth'e-turbine was taken'off.line and the reactor-brought to

cold: shutdown. to allow replacement of - the."A. Main Steam Safety Valve. _The

,7 drywell was entered, repairs made~and the unit placed back in service _at

0220fon~11/5/82.-

I The station operated at an average power' level of 99% due to main steam

' relief valve simmer. considerations. Other conaiderations affecting station

-powerflevel were fuel conditioning, condenser fouling, conden, sate demineralizer-

~

-differential pressure and control rod pattern changes.

N 1

During this period the -jockey fire pump ' failed and was' repaired. Control rod 10-31' experienced drive difficulties which were co'rrected. Probleme were corrected lLn the' HPCI control-circuitry and in motor operated valve 2301-03 which is. located.in:the HPCI: System..

The condensate demineralizers were backwashed frequently due to high differ-ential pressure.

RCIC pump operation was investigated du to low flow indication.(Ref. Maint. Summary) 01 11/11/82 power was ' reduced to 60% when the '!D" MSIV's had to be closed to-2 JallowfinsestigatiYn of'an apparent malfunctioning reactor' protection system (relay.- Ref.: cLER 82-054/03L-0.

~

L oni11/27/82 power was reduced to 50% due to main condenser fouling. The

main condense was backwashed.. heat treated and the ut.it returned to full power.

The month, ended at.99% with HPCI inoperable, awaiting repair of the HPcI 2301-3 motor; operated valve.

The following. refueling inforration is included in the Monthly Report as requested in a :1etter to Mr. G. C. Andognini dated January 18, 1978:

. For your convenience, the information supplied has been enumerated so that each number corresponds to equiv ient notation utilized'in the request.

1.

The name-of this facility is Pilgrim Nuclear Power Station, Docket Number 50-293.

2.

Scheduled date for'next Refueling Shutdown: September,1983,

3. ~ Scheduled date for rea, tart following refueling:~ November, 1983 4.

5.

Due to their similarity, requests 4, 5, & 6 are responded to collectively:

6.. ' The fuel, 'which had been, loaded. during the 1981 scheduled refueling outage, is of the same P8x8R desi.gn, as loaded the previous outage, con-sisting of 112 P8DRB282 assemblies.and 60 P8DRB265 as'semblies.

7. - (a). There are 580 fuel' assemblies in the core.

~

(b) There are'* 936 fuel assemblies' in the speIt fuel pool.

- 8.

(a) The station is present1u licensed to store 2320 spent fuel assemblies.

The acten1 spent fuel. storage capacity 'is 1770 fuel assemblies at present.

. (b) The planned spent fuel storage capacity is 2320 fuel assemblies.

. 9.

With present spent fuel in storage, the spent fuel pool now has the capacity to accommodate an additional 834 fuel assemblies.
