8/15/91 NARRATIVE

SUMMARY

MONTH: July 1991 Catawba Unit 1 began the month af Jnly operating at 100% full power.

The unit operated at or near 100% full power until 1400 on 07/04, when a load reduction was commenced for feedwater pump turbine '1B' governor valve maintenance. The unit was held at 65% power from 1800 to 2156 on 07/04, and returned to 100% futi :. ewer at 1255 on 07/05.

The unit operated at 100% full pcwer until 15s3 on 07/05, when a power reduction was begun for feedwater pump curbine '13' governor valve maintenance.

The unit was held at 65% power from 1815 on 07/05 to 2340 on 07/08, and returned to 100% full power at 0649 on 07/09, The unit operated at 100% full power until 0900 on 07/10, when a power reduction was commenced due to high feedwater pump delta p caused by loss of flow frnm the

'C' heater. drain tank pump.

The main turbine tripped from 92%

power at 0901 on 07/10 due to loss of both feedwater pumps on low suction pressure.

The reactor tripped on main turbine trip.

The unit was returned on line at 0352 on 07/12.

During the power increase, the unit was held at 30% power from 0900 to 19%9 on 07/12 for steam generator boron soak, and at 49% power from 0010 to 0424 on 07/13 for

'B' train condenser cooling water / condenser tube cleaning problems.

The unit returned to 100% full power at 0615 on 07/19, and operated at 100% full power until 2035 on 07/25, when a reactor shutdown was commenced due to refueling water. storage tank boron concentration being out of spec.

The power reduction was stopped at 74% power at 2150 on 07/25 pending evaluation of the boron sample results. At 2335 on 07/25, having found the samples to be in error, a power increase was begun. The unit reached 100% full power at 0738 on 07/26. and operated at or near 100% full power for the remainder of the month.
