1 81-018 HH INSTRU Upon the loss of the two operating CB SUP0RT feed pumps on low suction pressure, CC SUPORT the unit was manually tripped.
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.
