SUMMARY

.j JANUARY 1990 UNIT 2

(

?

Unit.2 generated 815,960 MWh (gross) of electrical power during January with k

a capacity factor of 92.71 percent. At the beginning of January, the unit was l

operating at approximately 75 percent power to extend the life of the core.

On January 4, 1990, at 0307:(EST), the power level was decreased for further maintenance on FCVs 6-105 and 6-106. The reactor reached 65 percent power at io 0430 (EST), on January 4, 1990, and maintained that power level until j

t maintenance was complete.

j n.

.On January 7,.1990,'at-1151 (EST), the SOS directed the Unit 2 operator to L

begin increasing the reactor power-level..The Unit reached 100 percent power 1

at 2121 (EST), that day.

3

-i Unit 2 continued to operate at approximately 100 percent power through the end of January, r
