SUMMARY

OF OPERATING EXPERIENCE January 1997 The unit began the month at 100% power.

On 01/25/97 at 0940 power was reduced to 85% to perform Main Turbine Control Valve testing. At the completion of the required testing, power was raised to 97% at 1935 to allow for waterbox cleaning and

{

heater drain tank maintenance. Power was returned to 100% on 01/26/97 at 0150.

The unit operated at 100% for the remainder of the month.

Feburary 14,1997

SUMMARY

OF OPERATING EXPERIENCE January 1997 t

The unit began the month at 95% power. The unit was operating at less than 100% as a conservative measure, due to a reduction in the cooling capacity of the main power output transformer (U-220000-22).

l Power was returned to 100% on 01/01/97 at 1420.

i Due to the reduced cooling capacity of the main power output transformer (U-22000-22) power was i

reduced periodically throughout the month, as indicated below, based on the outside ambient j

temperature.

On 01/02/97 at 1325 power was reduced to 97%. Power was further reduced to 95% on 01/03/97 at 1340. Power was returned to 100% on 01/06/97 at 2230.

On 01/22/97 at 1325 power was reduced to 97%. Power was further reduced to 95% on 01/23/97 at 1450. Power was returned to 100% on 01/23/97 at 2320.

i I

On 01/23/97 at 2350 power was reduced to 97%. Power was returned to 100% on 01/25/97 at 2030.

j On 01/28/97 at 0830 power was reduced to 97%. Power was returned to 100% on 01/28/97 at 1620.

The unit operated at 100% power for the remainder of the month.
