DOCKET NO. 50-317 CALVERT CLIFFS - UNIT 1 June 13,1997

SUMMARY

OF OPERATING EXPERIENCE May 1997 The unit began the month at 100% power.

On 05/29/97 at 1645, a rapid reduction in power was made due to indications of excessive reactor coolant system leakage At 1650 a reactor shutdown was commenced due to a leak on a pressurizer pressure instrument line compression fitting. The unit was removed from the grid at 1815 and the reactor was shutdown and in mode 3 (hot standby) at 1935.

The unit remained in mode 3 (hot standby) for the remainder of the month.

DOCKET NO. 50-318 OALVERT CLIFFS - UNIT 2 June 13,1997

SUMMARY

OF OPERATING EXPERIENCE May 1997 The unit began the month in mode 6 (refueling).

The following significant outage work was completed during the month:

- Reactor Vessel Refueling.

- Steam Generator Eddy Current Testing.

- Diesel Engine Operability Testing.

The outage ended when the unit was paralleled to the grid on 05/23/97 at 0119.

The unit was removed from the grid at 1507 on 05/23/97 to perform Main Turbine overspeed testing.

After the completion of the overspeed testing the unit was again paralleled to the grid at 1800.

Power was raised in increments to allow the required physics testing following the refueling outage. The unit reached 100% on 05/29/97 at 2050.

The unit operated at 100% for the remainder of the month.
