b REFUELING INFORMATION The following refueling information is included in the Monthly Report as requested in an NRC letter to BECo, dated January 13, 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: September 1986

3. Scheduled date for restart following refueling: November 1986

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

5. See #6. ,

!. 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 P8DRB282 assemblies. In addition, 32 GE6B-P8DRB282 assemblies were also l loaded.

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

I (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 M1942 fuel assemblies at present.

l (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 i capacity to accommodate an additional M814 fuel assemblies.

BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 Operational Summary for January 1986 The unit was operated at full power until the fourth when a planned shutdown was made to investigate high vibration on the #9 turbine bearing. Subsequent to maintenance activities, including realignment of the exciter, an unplanned scram occurred while starting up. The unit was returned to service on the seventh with satisfactory turbine vibration.

From the eighth through the tenth, reactor power was increased slowly as limited by new and more stringent water chemistry guidelines. Full power was reached on the eleventh and maintained until the sixteenth when a reactor scram occurred due to a false high reactor pressure signal.

The unit was returned to service on the eighteenth and achieved full power on the twentieth. Full power was essentially maintained through the end of the month with the exception of the twenty ninth when a slight power reduction was made to investigate high vibration on the #9 turbine bearing. The vibration problem was quickly resolved.

• An unusual event was declared on the tenth due to a fire at the hydrogen storage tank area. The fire was extinguished within approximately 30 minutes with essentially no injury, damage or loss of generation.

a Safety Relief Valve Challenges Month of January 1986 Requirement: NUREG-0737 T.A.P. II.K.3.3.

There were no safety relief valve challenges during the month.
