SUMMARY
AUGUST 1983 UNIT 2 The Unit began the month at 100% full power. The Unit was brought to 90% power on August 2 and again on August 5 for packing replacement on Heater Drain Pump "B". On August 10, power was reduced to 82% limited due to 5" Hg exhaust pressure on LPT-8. On August 16, power was reduced to 25% for steam generator boron addition and remained there through August 22. The Unit was brought to 88% power again limited due to steam generator level following an electrical transient during a diesel generator surveillance. The Unit remained offline throughout the and of the month due to an RCP seal replacement and other maintenance.
