MONTHLY OPERATING ACTIVITIES - JUNE 1988 The unit operated at the 90$ administrative power limit upon entering this reporting period until 1616 on June 6,

1988, when a power reduction was started due to a substantial steam leak on the east MSR.

The leak was located at the drain tank vent line elbow connection to the MSR shell.

Power was reduced to 30Ã at 2233, at which time the steam leakage was reduced to an acceptable level for repair.

The leak was repaired and power ascension to 90K performed between 0513 and 1910 on June 9, 1988.

The reporting period ended with the unit operating at its 90K administrative limit.

Gross electrical generation for the month of June was 638,760 MWH.

DETAILS 06-06-88 06-09-88 1616 2233 0513 1910 Comenced power reduction due to the vent line leakage on the east MSR.

Reactor power at 30K.

Power reduction completed.

HB PIPEB Reactor power was reduced to 30K to permit repair of a substantial steam leak on the east moisture separator-reheater shell drain tank vent con-nection at the HSR shell.

The cause of the leak was determined to be erosion/corrosion.

A weld irregu-larity was found that may have contributed to the failure.

The vent line was repaired by welding a larger diameter pipe over the damaged pipe.

Reactor power was returned to 90K on 880609.
