At 0726 on November 12, 1982 with the unit at 100% power the reactor tripped resulting in a turbine generator trip. The first out annunciator was " Reactor Trip-Turbine Trip", which
~from the sequence of events recorded occurred as a result of "A" Reactor Trip Breaker opening. Recovery following the' trip
.was normal as the plant was stabilized in Hot Standby (Mode 3) l condition within minutes after the trip-occurred.
Investigation into the cause for "A" Reactor Trip Breaker opening, including a functional check of the Solid State Protection System, uncovered no failures. Therefore, the cause of the trip is considered to be. a spurious actuation of "A" Reactor Trip Breaker.
82-20 (A)
. (9).
At 0707 on November 30, 1982 with the unit at-100% with "A" condenser waterbox just returned to service and "C" condenser waterbox just having been removed from service as per the Chemistry Department due to suspected condenser tube leaks, the'"B" Notwell level went low due to unusually slow equalizat-ion from the "A" Hotwell following the removal of "C" waterbox 4
from service. This caused the Condensate Pumps to cavitate.
The "B" condensate-Pump auto started. -The feed pumps suction
. pressure was still low causing "A" Main Feedwater Pump to trip.
~Tne Turbine was run back in manual to 94% power and the "A" Main Feedwater Pump restarted with adequate suction pressure now available. ~The unit was stabilized at 94% following the transient. A unit rampdown was commenced due to excessive Cation Conductivity in the Steam Generators. The unit was stabilized at 30% power for secondary chemistry hold. The sg.
month ends with ths unit at 30% power with further investi-gation into suspected condenser tube leaksuin progress while in the secondary chemistry ho13.
