SUMMARY

HONTH: January 1991 Catawba Unit 1 began the month of January operating atl100% full power.

The unit operated at or c. ear 100% full power until 0900 on 01/04, when a reactor shutdown was commenced for investigation of a main generator ground fault.

The unit was taken off line at 1724 on 01/04. An ice condenser u. bolt inspection took place during this outage, and was critical path for a majority of the outage duration.- The unit was placed on line at 0243 on 01/13. During the subsequent power increase, the unit was held at 15% power from 0305 to 0700 on 01/13 for NIS-adjustment and main feedwater uozzle swap.

The unit was next held at 21% power from 0800 to 1335 on 01/13 due to a feedwater system valve (1CF33) failure. A hold at 30% power was commenced at 1500 on 01/13 for steam generator boron soak. A power increase was then begun at 0912 on 01/14.

power escalation was atopped at 486 power at 1400 on 01/14 foi reactor coolant system laakage calculation. At 1958 on 01/14 a power decrease was commenced to restore "A" train power (recovery from zone "A" lockout incurred by main transformer "1A" malfunction).

The reduction was halted at 404 power at 2100 on 01/14.

A power increase was then begun at 2218 on 01/14 The unit reached 90s power at 1600 on 01/15, and was held there until 1800 on 01/15 for turbine control-valve movement testing.

The unit reached 100% full power at 0045 on 01/16, and opereceu at 100% full power until 0321 on 01/30. At this time, the unit had e turbine runback initiated by a spurious indication of "1A" feedwater pump turbine trip.

The runback was halted at 72% power at 0330 on 01/30.

A power re' duction was begun.

at 0814 on 01/30 to remove feedwater pump "1A" from service, tais reduction was stopped at 644 power at 1013 on~01/30. At 0541 on 01/31, a power reduction was comme?.cd due to core quadrant power' tilt ratio in excess of 2s.

The reduction was stopped at 46's at 0700 on 01/31.

The unit ended the month operating at 46% power, prepared by:

SUMMARY

MONTil: January 1991

{

Catawba Unit 2 began the month of January operating at 984 power, limited due to steam generator "D" feedwater preheater max flow.

The unit operated at or near 98% power until 0015 on 01/05, when a reactor shutdown was commenced due to ice condenser u bolt inspection.

During the reduction, the unit was held at 954 power from 0100 to 0127 on 01/05 for control rod movement tasting, and at 154 power from 1126 to 1341 on 01/05 in preparation for taking the Generator off line. The l

unit was taken off line at 1341 on 01/05. At:2129 on 01/09, the unit was placed on line, and a nuclear instrumentation calibration was-performed.

A power increase was commenced at 0125 on 01/10, and the unit reached 99% power at 0411 on 01/11. The unit operated at or near 994 power for the remainder of the month.
