January 8,
1988, at 0438 reactor manually tripped from 100%
power - 968 MW, due to loss of circulating water pumps.
Repairs were completed and Unit returned on line January 13, 1988 at 0307.
08-02 2)
January 13, 1988 at 0313, reactor trip occurred at 100 MW - 15%
- power, due to Hi Hi level on "B" steam generator.
Corrective action was taken and January 13, 1988 at 1125 reactor was taken critical.
Approximately eight hours later, the reactor was manually shutdown due to resin intrusion in the steam generator.
Ended the month with Unit in Mode 5, repairing the 1-RC-P-1A reactor coolant pump seal and flushing the steam generator after powdex resin intrusion.
Approximately February 5, 1988, the Unit will return on line.
