- I. Monthly Report for'Braidwood Unit;l

.A.. Summarv' of Ooeratina Experience-The unit entered the month of June at approximately 95%

-power. On. June 25. the failure.of a condensate make-up pump.to auto start caused a low condenser hotwell , level and forced'a 50% power. reduction. Unit' capability was-1 restored on June'29, and.' continued power operation!though
