For your convenience, the information supplied has been enumeratet' to that cach number corresponds to equivalent notation utilized in the request.

1 The name of this facility is Pilgrim Nuclear Power Station, Docket No. 50-293 2

Scheduled date for next P.efueling Shutdown:

January 1980 3.

Scheduled date for restart following refueling:

April, 1980 4.

5.

Due to their similarity, requests 4, 5 & 6 are responded to collectively-6 The fuel, which is presently expected to be loaded during the next scheduled shutdown, may be reload fuel ot a neu design and may therefore require a proposed license submittal and technical speci fication changes.

It is not possible, however, to supply pertinent information on dates.

As information concerning fuel design, core configuration, Operational Review Committee determinatiens, proposed licensing action, and technical specification submittals becomes available, it will be forwarded to you.

7 (a)

There are 580 fuel assemblics in the core, (b)

There are 580 fuel assemblies in the spent fuel pool.

v-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 assemblics.

9.

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

BOSTON EDISO'1 COMPANY PILGRIM NUCLEAR POWER STAT 70N DOCKET NO. 50-203 SUFNARY OF OPERATIONS FOR JANUARY, 1979 The month of January, 1979 began with the unit operating at 100% power.

The unit remained at 100% power level until 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> on January 25, 1979, at which time a power reduction was necessary due to a high condenser di T.

This was the direct result of a severe storm which resulted in extremely heavy seas which caused seaweed to foul our main condenser tube sheets. At 1936 hours0.0224 days <br />0.538 hours <br />0.0032 weeks <br />7.36648e-4 months <br />, Operations personiel began backwashing the main condenser and at 2330 hours0.027 days <br />0.647 hours <br />0.00385 weeks <br />8.86565e-4 months <br /> the condenser backwash was completed and the reac tor power level was increased to 100%.
