SUMMARY

OF OPERATIONS FOR h0 NTH OF JULY Unit was operating at 100% power until July 11' when power was reduced to 70%

to correct rod pattern due to control rod 22-39 being inserted to 00 due :o problems with rod. Rx power was returned to.100% at 0900 on July 11, 1982.

July 13, started trimming power over low tide to maintain condensere.T below 32 F. July 17, 1982, power was reduced to 50% to backwash and heat treat the

. condenser. Control Rod 22-39 was withdrawn to position 48 and unit was returned to 100% Rx power on July 19, 1982.

On July 20, power was reduced to 70% due to alans on Main Steam hi radiation caused when putting "C" demin on line.at.1535. Unit was returned to 100%

at 1925.

HPCI was declared inoR on July 21, 1982 and returned,to service en July 22, 1982.

July 31, power was reduced to 50% to backwash and heat treat condenser.
