The Unit entered'the reporting period in Mode 1 with the

? reactor at 100% of rated thermal power. Major power reduc-tions occurred for.the following reasons:

1) To-remove-the Main Feed Pumps from service (to clean debris-from-the feed pump turbineicondensers.

2) To lubricate the circulating water system de-icing valves.

13)~ To remove the West Main Feed Pump ~from service for a "

condenser tube' leak check.

4). To remove-the East'and West Main Feed Pump from service for condenser tube leak. checks.

The Unit ended the reporting period at 75% rated-thermal power.-

Total electrical generation for the month was 711,720 MWH.

SUMMARY

11-07-84 North Safety Injection-Pump inoperable at 0518 to repair -

L 11-12-84 At 0447-the East Main Feed Pilmp was returned to service 4

and the West Main Feed Pump was removed.from' service to clean ~ debris.from the feed pump turbine-condenser.

11-12-84 At -0903 the West Main Feed Pump was returnedito service j

1 and at 1640 power was returned-to 100%.

11-23-84 At 0005 tia power was reduced to 77% to lubricate the circulating water system de-icing valves.  !

R 11-24-84 At:0118 the power was further reduced to 55%.to remove- 'l the' West Main Feed Pump from service to check for': tube ~ j
