The CH SUPORT loss of pump sucticn pressure was CF SUP0RT apparently caused by a perturbation in the feed system, which was brought about by the failure of a computation module, located in the steam generator level control system. The unit was placed in cold shutdown for a 14 day mechanical snubber outage and subse-quently returned to nonval full power operations.

Sumary: The unit operated at or near 100% of rated thermal power throughout the report period except for the g outages of the 5th and 16th.
