SUMMARY

OF OPERATING EXPERIENCE UNIT TWO FEBRUARY, 1980 Unit* Two started the month operating at a power level of 705 MWe.

On February 3, at 0040, Unit Two scrammed on low vacuum while transferring the Max-Recycle reboiler relief discharge line from Unit Three condenser to Unit Two condenser.

2-3 to 2-29 The Unit was ~laced back on line at 1120 on February 3 and operated the remainder of the month at an average power level of 724 MWe, with a capacity factor of 90.6% for the entire month.

SUMMARY

OF OPERATING EXPERIENCE UNIT THREE FEBRUARY, 19 80 2-1 to 2-2 Unit Three started the month operating at a power level of 508 MWe.

On February 2, at 1040, Unit Three was taken off line due to an inoperable jet pump.

2-3 to 2-29 Unit Three commenced its scheduled re-fueling outage at 0800 on February 3, 1980.

By the end of the reporting period, all fuel had been removed, and CRD replacement completed.

Other major activities for this reporting period and for the remainder of the outage in-elude:

jet pump repair and inspection, installation of vent header deflectors, and downcomer support bracing in the torus.
