SU121ARY OF OPERATING EXPERIENCE OPERATION:

The plant' began and ended the month at power operation. The1 reactor coastdown continued in accordance with the scheduled approach to the April refueling.

On 3-2-80, one feedwater train was taken out of service when the steam-driven feedwater pump developed high vibration.

The primary-to-secondary steam generator tube-leak remained small at about 30 gallons per day.

MAJOR SAFETY-RELATED MAINTENANCE:

Work continued on improvement modifications to'the Plant Security and

- the Fire Protect. ion. Systems.
