l DOCKET NO. 50-318 CALVEf,T CLIFFS - UNIT 2 January 15,1997

SUMMARY

OF OPERATING EXPERIENCE l

Dgcember 1996 j

The unit began the month at 100% power.

On 12/23/96 at 1225, power was reduced to approximately 95%, as a conservative measure, due to a reduction in the cooling capacity of the main power oatput transformer (U-220000-22).

I Power was maintained between 95 - 100%, based on the outside ambient air temperature, for the remainder i

l of the month.
