SUMMARY

Month: July, 1988' Catawba Ur.it 1 Catawba Unit 1 began the month of July operating at 100% full power. On 7/19.at 0103, the unit reduced power to 30% due to the Feedwater System chemistry out-of-spee. On the unit's return to 100% full power, power escalation was halted at 65% power to place the second Main Feedwater Pump in service, 82%

power te adjust the High Flux Trip Setpoint, and at 91% power.to calibrate Nuclear Instrumentation. The unit reached 100% full power at 1216 on 7/20.

The unit'. reduced power to 96% on 7/23 to remove the '1C2' Heater: Drain Pump from service. The unit returned to 100% full power at_1200 on 7/24. The unit i reduced power slightly on 7/24 and again on 7/26 due to Heater Drain Pump problems. The unit returned to 100% full power on 7/27 where it operated for the remainder of the month.

SUMMARY

Month: July, 1988 >

Catawba Unit 2 Catawba Unit 2 began the month of. July at 100% iull power. On 7/01 at 2009 the-unit reduced power to 95% to remove the '2C2' Heater Drain Pump from service for repairs. On 7/02 at 2000, the unit reduced power from 95% to 60% and later to 40% to help the Dispatcher meet minimum system load. The unit returned to 100% full power on 7/05 at 1934 following a hold at 93% pvver for Nuclear Instrumentation Calibration. On 7/06 at 0430, the unit reduced power to 90% per the Dispatcher and returned to 100% full power on 7/06 at 0950. The unit was taken off-line on 7/17 at 0153 to repair Centrifugal Charging. Pump '2A'. The unit returned to service on 7/22 at 1627. At 1628 the same day the turbine / generator tripped due to spurious anti-motoring relay actuation. The unit returned to service at 1709 on 7/22, on returning to 100% full power the unit. held, at 46% power per the Dispatcher and to calibrate Nuclear Instrumentation, at 90% power for Turbine Control Valve Movement Test, and at 98% power for Nuclear Instrumentation Calibration. The unit reached 100% full power at 0200 on 7/24, follow a reduction due to '2C1' Heater Drain Pump seal replacement. The unit reduced power on 7/25 at 1800 to 90% for Turbine Cont.rol Valve Movement Test and returned to 100% full power on 7/26 at 0530 where it operated for the remainder of the month.
