SUMMARY

OFOPERATING EXPERIENCE i

April 1993 e

He unit began the month at 100% (875 MWe).

j Power reduction commenced at 0014 on April 3 to repair #12 Heater Drain Tsnk Normal Imel Control Valve and to clean condenser waterboxes. Power variations were mr.de with the lowest power level being 89% occurring at 0130. The power was agam restorea to 1007c at 0225 on April 5.

Because of difficulty in maintaining proper differential temperature across the condenser, power was l

a reduced at 0230 on April 8 for cleaning 13A Waterbox. Due to further problems maintaining proper differential temperature,13A Waterbox was restored to service and power was returned to 100%

j (875 MWe) at 0335. At 2200, power reduction commenced to remove vegetation debris from the -

inlet strainer valve. The power was restored to 1007c at 0620 on April 9.

Power was decreased to repair a tube leak in 11B Condenser Waterbox and was again restored to 100% at 1700 on April 20.

r i

Commencing at 0330 on April 24, power was reduced for maintenance on 13B Amertap and 11 i

Heater Drain Pump Normal Inci Control Valve. Power was restored at 1700 to 100% power.

{

The unit finished the month at 100% (870 MWe).
