See #6.

6.

The new fuel, which was loaded during the 1983-84 refueling outage, is of the same P8x8R design, as loaded the previous outage and consists of 160 P80RB282 assemblies. In addition, 32 GE6B-P8DRB282 assemblies were also loaded.

7.

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

(b) There are 1,128 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 acccmmodate an additional 642 fuel assemblies.

BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCMET NO. 50-293 Operational Summary for August 1995 The month commenced with the unit at full power.. On the second, power was reduced to perform a condenser backwash. The ~ unit was returned to full power on tb / third and maintained at that level until the twentieth when power was again reduced for a condenser backwash.

~

On the twenty-first, the unit was returned to full power and maintained at that level until the thirty-first when power had to be trimmed in response to heavy seas emusing fouling of the travelling screens.

During the month, periodic slight power level reductions were required at low tide in order to maintain condenser vacuum.

Equipment qualification work remained in progress throughout the month.

Safety Relief Valve Challenges Month of August 1985 Requirement: NUREG-0737 T.A.P.
