. NARRATIVE

SUMMARY

7 MONTil: January, 1982 Oconce I began the month of January at 15% power, following an extended outage for refueling, and core support assembly bolt replaccment.

On January 1, a level control problem on the moisture separator reheater drain tank was the cause of three (3) trips of the turbine / reactor.

Another trip occured on January 2, due to a false loss of stator coolant signal.

Power escalation testing at the 40% Icyc1 began on January 4 and was completed on January 6. On January 6, the unit was forced from service due to high vibration on turbine bearing #11.

A generator hydrogen leak and high pressure feedwater heater tube Icaks extended the outage until January 30.

'Ihe reactor remained critical while the generator was removed from service on January 30 for a turbine balance shot. At the month's end, the unit had been returned to service and was increasing in power.
