REFUELING INFORMATION The following refueling infor: nation 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: December, 1983

3. Scheduled date for restart following refueling: April, 1984 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 design, as loaded the previous outage consisting of 112 P8DRB282 assemblies and 60 P8DRB265 assemblies.

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

(b) There are 936 fuel assemblies in the spent fuel pool.

8. (a) The station is presently licensed to store 2320 spent fuel assethlies.

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 834 fuel assemblies.

BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 Operational Summaary for October 1983 The month commenced with the unit at 35% power in order to facilitate a special HPCI surveillance test. After successful completion of tha. test the unit was returned to 94% power (maximum achievable due to fuel depletion) until October 7 when the unit was shut down as planned to allow photographing of.the drywell and performance of planned maintenance. While shutting down, the turbine bypass valves opened further than required due to a problem with electronic pressure regulat3 n system and the reactor scrammed on low pressure

- ( 880 psig while in the re- mode).

Upon completion of planned outage activities the unit was returned to service on October 10, 1983. Maximum power attainable was maintained until the end of the month at which time the unit was at 87% power.
