78-9 (G) Unit was not in service. In the course of a Rx startup, the operator failed to block the source range high flux Rx Trip (PG).
79-10 (G) Turbine Trip / Reactor trip when too much water was added to the steam generators causing "B" S/G to swell to the !!i-Hi Level Trip point.
79-11 (G) Reactor / Turbine / Generator Trip from steam flow / Feed flow mismatch and low S/G water level.~ When condensate was valved into the flash evaporator to increase plant performance, differential pressure created across the heat exchanger caused feedpump suction press to decrease causing feed flow to decrease to the point where S/G level could not be maintained.
79-12 A High bearing temperature on "C" main feedpump required a reduction in megawatt load when the feedpump was removed from service.
