NARRATIVE

SUMMARY

Month: April, 1988 Catawba Unit 2 began the month of April at 45% and decreasing, to repair a S/G Feedwater Control Valve. The repair was completed and power escalation was begun at 0405 on 4/04. The unit reached 100% power on 4/05 at 0310, following power holds at 65%, 90%, and 98%, for a Reactor Coolant System Leakage Calculation, a Control Valve Movement Test, and Nuclear Instrumentation Calibration, respectively. The unit reduced power to 90% at 1830 on 4/05, due of the Inadequate Core to an indication of low subcooling margin on Train "A" Cooling System. The unit then began increasing power at 2144 on 4/05,The and held unit power at 95% to repair a Feedwater Heater Drain to Condenser Valve.

returned to'100% power at 1755 on 4/07, following a power hold at 98% for On 4/08 at 2236, power was reduced to 60% to repair precision calorimetrics. The unit returned to 100% power at the "2B" condensate Feedwater Pump Turbine.

2237 on 4/11, following a hold at 90% power for Nuclaar Instrumentation Calibration. At 1645 on 4/22, a power reduc lon to 60% was commenced due to low system load. The unit then operated at 60% power until 4/23 at 2015, when a The unit was unit shutdown was commenced to repair an Exciter Field Ground.

removed from service at 0537 on 4/24, and finished the month of April in a Maintenance Outage.
