DOCKET NO. 50-317 CALVERT CLIFFS - UNIT I August 15,1996 r

SUMMARY

OF OPERATING EXPERIENCE lulv1996 The unit began the month in Mode 5 (cold shutdown), in a forced extension of the refueling outage, due to an internal short on i1B Reactor Coolant Pump Stator.

The motor for 1IB Reactor Coolant Pump was replaced. On 07/07/96 at 0610 while performing a plant heatup, high vibrations were detected on 1IB Reactor Coolant Pump. Investigation identified that the suction diffuser was detached due to a failed locking device. This caused the impeller to be unbalanced.

The pump was repaired and the other reactor coolant pumps were inspected to verify the integrity of their locking devices.

j Plant heatup was commenced on 07/27/96 at 2025. The reactor reached criticality on 07/29/96 at 1652.

The unit remained in Mode 2 (startup) to perform low power physics testing through the end of the month.
