SUMMARY

OF OPERATING EXPERIENCE UNIT ONE 1-1 to 1-31 JANUARY, 1981 Unit One was shutdown for the entire month, awaiting license approval for the chemical cleaning.

Major work scheduled to be completed following chemical cleaning is as follows:

HPCI installation for ECCS upgrading, equip-ment upgrade to IEEE 279, major in-service inspection, and refuel.

1-1 to 1-3

SUMMARY

OF.OPERATING EXPERIENCE UNIT TWO JANUARY, 1981 Unit Two started the month operating at a power level of 350 MWe.

On January 3, at 2124 hours0.0246 days 0.59 hours 0.00351 weeks 8.08182e-4 months , Unit Two was taken off line and conunenced its scheduled refueling outage.

1-4 to 1-31 By the end of the reporting period, all fuel has been removed and maintenance work is being accomplished as scheduled.

The Unit had a capacity factor of 3.55%

and an availability of 9.33%.

SUMMARY

OF OPERATING EXPERIENCE UN.IT THREE 1-1 to 1-2 1-2 to 1-5 1-5 to 1-il 1-11 to 1-31 JANUARY, 1981 Unit Three entered the month at a power level of 695 MWe and load was steadily in-creased at 5 MWe per hour throughout the day.

At 2050 hours0.0237 days 0.569 hours 0.00339 weeks 7.80025e-4 months , the reactor auto-matically scrannned because of a hi-hi water level in the 3A Moisture Separator Drain Tank.
