O NRC MONTHLY OPERATING REPORT OPERATING SUHARY - MARCH, 1980 UNIT I During the first six days of March, the unit operated at 100% reactor power.

On Friday, March 7, the unit was taken off line and later brought to cold shutdown due to a main condenser vacuum leak. The leak was caused by a tear in the rubber expansion joint connecting the LP-2 turbine to the condenser.

Repairs were made and the unit reached 100% reactor power on March 13.

The unit overated normally for the remainder of the month.
