G-OPERATIONAL ERROR (EXPLAIN) i H-OTHER (EXPLAIN)

EVENT 94-1 CAUSE: The initiating event for this reactor trip was the operation of a differential relay on a shunt reactor in the high voltage switchyard which resulted in the trip of two 500 kV air blast circuit breakers (ACB), one of which was the Unit 2 main generator ACB. After operation, the two ACBs had low air pressure indications which served as a permissive in the breaker failure protective relaying scheme. This resulted in simultaneous tripping of the back-up breakers, including the remaining Unit 2 main generator ACB. This resulted in a generator trip followed by a turbine trip and reactor trip.

CORRECTIVE ACTIONS: The shunt reactor was removed from service pending further testing and analysis. Air pressure for the ACBs was restored to normallevels and the breakers were verifieJ to operate properly. The main generator ACBs were then returned to service, allowing unit startup to commence.

i EVENT 94-2 CAUSE: The initiating cause of this event was tripping of the "B" heater drain pump (HDP). This ultimately led to water i

entering the "C" and "D" MSRs, which generated the turbine trip signal j

CORRECTIVE ACTIONS: Troubleshooting verified no abnormal condition of the HDT pump. Level controllers and -

associated level switches in the MSRs, MSDTs and HDT were inspected to ensure proper operation.
