SUMMARY

UNIT 2 sm;WlY - JULY, 1976 .. TELEPHONE&'5': *~~ <:.:~'. - x ~;;l~s-~*;

nresden! 2 entered the month of July at 475 MWe and increasirtg. The major load limiting facto:rs-- .. -*'"'. :) .* . ~' ..

were lo¥ condensate booster pump suction pressure and high circulating water inlet temperatureso Though not a limiting factor, the A recirculation pump motor was rmming warm. The cooling lake lift puttps. were lost for approximately an hour ori 6/8/76 and 6(26/76.*

• The nionth ended with the unit at- approximately 800 MWe and yielding a.vailability/capacity factors of ~00/91.6 percent.
