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: January, 1984
- 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 autage 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 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.

PILGRIM NUCLEAP POWER STATION OPERATIONAL
SUMMARY
FOR APRIL, 1983 Note: Reactor pressure is limited to 1030 psig due to safety / relief valve simmer margin considerations.
The unit was operating at 100% available reactor power on April 1, until power was reduced to 50% to backwash and heat treat the main condenser.
While at 50% power, 11 control rods were scram timed. On April 2, the stator cooling temperature control valve stayed full open causing turbine runback on high stator temperature which resulted in the unit scramming on high flux. While the unit was off line, it was found that "B" Recirculation Pump MG set field breaker would not trip. (Ref: LER 83-013/01T-0). After minor maintenance, the unit was restarted on April 3. The unit was synchronized onto the grid on April 4 and power was increased to 95%. On April 5, a turbine runback occurred due to stator cooling alarm and power was manually reduced to 50%. Power was subsequently increased to 95% and remained at that level while the investigation of the stator coolant system continued.
The unit returned to 100% power on April 8. A reduction to 70% was made on April 9 when two control rods drifted in during control rod exercises. A return to 100% power was achieved the same day. On April 13 RCIC was de-clared inoperable due to a motor failure on the 1301-17 MOV (Ref: LER 83-022/03L-0).
After the valve was repaired, the system was returned to service on April 15.
A leak in the extraction steam line for the 2nd point heater for the "A" train was found on April 16 and on April 17 power was reduced to 50% to repair the leak and backwash the main condenser. Following this maintenance, the unit was returned to 100% power. On April 20, HPCI was made inoperable for scheduled maintenance and was returned to service the same day.
On April 22, the extraction steam lines were inspected after power was reduced to 50% and while at reduced power, the main condenser was backwashed. On April 23, the unit was again at 100%. The "A" Standby Liquid Control pump was made inoperable for maintenance and was declared operable on April 30 when the unit output was reduced to 70% for control rod exercises. A return to 100% was made the same day.
