REFUELING INFORMATION The following refueling information is included in the Monthly Report as requested in a letter to Mr. G. C. Andognini 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: Sep tember,1983

3. Scheduled date for restart 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 design, as loaded the previous outage con-sisting 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 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 834 fuel assemblies.

BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION Summary of Operations for JANUARY, 1983 The unit operated at 100% (MWE) until 1/2/83 when power was reduced for control rod exercises and returned to 100% the same day. Condensate demineralizers were worked on throughout the month.

On 1/5/83, reactor water sample isolation valve, A0-220-44, was found to be inoperable.

The redundant in-line valve, A0-220-45, was isolated and red tagged closed to comply with Technical Specifications (Ref: LER 83-001/03L-0). On 1/9/83, power was reduced to 90% for control rod exercises and returned to 100%.

On 1/15/83, power was reduced for condenser backwash, surveillances and to repair oil leaks on the "A" reactor feedwater pump.

On 1/6/83, control rod number 10-31, could not be withdrawn and was electrically disabled at position 00. The supply breaker for the "A" RPS was found to be overheated cnd a h scram was initiated until replacement was made. (Ref: LER 83-004/03L-0).

R2 turn to full power was made later the same day (1/16/83).

A reduction in power to 90% was made on 1/23/83 for control rod exercises and rod number 06-15 drifted to position 10. A further reduction to 70% was made, the rod withdrawn to position 48 and return to 100% was achieved.

A condenser backwash on 1/29/83 required a power reduction to 50% and control rod 10-31 was moved to position 48 and electrically disabled. Twenty five additional control rods were timed and the unit returned to 100% power.
