11 BOSTON EDISON COMPANY PILCRIM NUCLEAR POWER STATION l l

{ Summary of Operations for Februar,y, 1983 1 i The month began with the unit operating at 100% reactor power. The "A" TBCCW f

heat exchanger was out of service to repair leaking tubes. It was returned to j service 2/3/83. On 2/5/83 while performing control rod exercise, control rod

) 22-39 inserted to position 16. Reactor power was reduced to 65% to withdraw l ,

the rod and returned to 100% power. On 2/7/83 "B" TBCCW heat exchanger was removed from service to repair leaks. On 2/12/83 "A" standby gas treatment system was declared inoperable to replace charcoal in the filters. The reactor scrammed on 2/13/83 due to load reject at 0)39. At 1025, a loss of offsite i

] power due to salt buildup in the switchyard occured from a Northeast storm. "A" i

i standby gas treatment system filter was declared operable 2/16/83. The reactor 1

was brought critical at 1745 on 2/14/83 and synchronized onto the grid at 0047 4

on 2/15/83.

1 i

100% power was achieved on 2/17/83.

on 2/20/83 while exercising control rods, rod 18-31 inserted to position 26.

Power was reduced to 65%, the rod was withdrawn and the unit returned to 100%

i reactor power. On 2/24/83 "B" standby gas treatment was declared inoperable i

J due to solenoid valve on sprinkler system leaking causing charcoal to become 1

wet. "B" SBGT was returned to es rvice 2/28/83.

I i

i Safety / Relief Valve Challenges for the month of February, 1983 There were no challenges to relief valves during February.

e 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 inforumtion supplied has been enumerated so that each number corresponds to equivalent notation utilized in the request.

1. The name of this facility is Pilgrim Nuc1 car Power Station, Docket Number 50-29 3.

2. Scheduled date for next Refueling Shutdown: September, 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.
