BOSTON EDISON COMPAW PILCRIM NUCLFR POWER STATION

SUMMARY

OF OPERATIONS FOR JU':E, 1979 The station was recovering fren the snubter modification outage at the beginning of June. Reactor Pcwer was 85% on June 1 and increasing at 10MW /hr per PCICMR.

Reacter Power reached 100% on June 3, 1979 and continued at this level until June 16, 1979 except for minor power reductions to naintain main condenser delta temperature. On June 16, 1979, the unit was shutdown to replace a weeping safety relief valve and perform other planned =aintenance.

The unit was started up on June 17, 1979 and synchronized to the systen at 1613 hours0.0187 days <br />0.448 hours <br />0.00267 weeks <br />6.137465e-4 months <br />. Reactor pcwer reached 100% again on June 21, 1979 and continued at this level for the remainder of the month.

REFUELING INFOrtCION The f ollowing refueling inf ormation 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 f acility is Pilgrim Nuclear Power Station, Docket No. 50-293

2. Scheduled date for next Refueling Shutdown: January, 1980

3. Scheduled date for restart following refueling: April, 1980 4

5. Due to their similarity, requests 4, 5 and 6 are responded to collectively.

6. The fuel, which is presently expected to be loaded during the next scheduled shutdown, may be reload fuel of a new design and may therefore require a proposed license submittal and technical specification change. It is not possible, however, to supply pertinent information on dates. As information concerning fuel design, core configuration, Operational Review Committee determinations, proposed licensing action, and Technical Specification submittals becomes available, it will be forwarded to you.

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

(b) There are 580 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 1160 fuel assemblies and new high density fuel storage racks are in the process of being installed.

(b) The planned spent fuel storage capacity is 2320 fuel assemblies.

9. b'ith present spent fuel in storage, the spent fuel pool now has the capacity to accommodate an additional 580 fuel assemblies (one core).
