P NIAGARA M0 HAWK POWER CORPORATION HINE fille POINT NUCLEAR STATION UNIT #1 NARRATIVE OF OPERATING EXPERIENCE December 1978 The station operated continuously during the month of December with an average capacity factor of 87.5%. The cumulative totals for 1978 are 95.1% availability and 83.6% capacity.

The monthly operating history is as follows:

December 1-4 flaintained load at approximately 570 MWe with reactor recirculation flow at an all rods out configuration until reaching 100% recirculation flow on December 4.

December 5-31 End of cycle coastdown in progress; coastdown rate approximately 5 MW(t) per day.

On December 22, reduced load from 538 MWe to 500 MWe for a coadensate demineralizer change, returning to 530 MWe upon completion.

On December 31, the last reporting day of the month and year, generator output was 521 MWe.
