-BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 Doerational Summary for February 1985 The unit was operating at 100% on the first of the month when it became necessary to isolate the "B" steam line due to a timing problem with the inboard MSIV. This'resulted in a power reduction to 75% which continued through the eighth.

l Problems with the "A" recirculation pump motor resulted in a manual shutdown of the reactor on'the tenth. The reactor remained shut down until the fifteenth during which time the recirculation pump motor thrust bearing was replaced and the "B" inboard MSIV was repaired.

The reactor was made critical on.the fifteenth at which time the vessel drain line was found to be leaking.. The: reactor was placed in cold shutdown. The leak was repaired and, on the eighteenth, the generator was synchronized to the grid.

Power was increased to 100% on the twentieth and was maintained until the twenty-sixth at which time power was reduced to approximately 75% due to erratic operation of the "A" feedwater control valve proportional amplifier.

Upon replacement of the amplifier on the twenty-seventh, power was increased L

to 100% and was amintained through the end of the month.

A REFUELING INFORMATION The following refueling information is included in the Monthly Report as

. requested in an NRC letter to BECo, dated January 18, 1978:

For your convenience, the information supplied has been enumerated so that each number corresponds to equivalent 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: August 1986 3.

Scheduled date for restart following refueling: November 1986 4.

5.

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

6..'The new fuel, which was loaded during the 1983-84 refueling outage, is of the same P8x8R design, as loaded the previous outage and consists of 160 P80RB282 assemblies.

In addition, 32 GE68-P80RB282 assemblies were also loaded.

7.

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

(b) There are 1,128 fuel assemblies in the spent fuel pool.

8.

(a) The station is presently licensed to store 2320 spent fuel assemblies. The actual 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 642 fuel assemblies.
