Summary of Operating Experience March 1985 Unit 2 operated at 100% power until March 6th. On March 6th, the reactor automatically ' tripped on a combination of #23 Steam Generator Iow Level and mismatch between steam flow an'd feed flow to #23 Steam Generator.

The cause of the trip was the -failure of the relay in the #23 Steam Generator ' level controller during a surveillance test.

The' unit was restarted on March 7th and remained at 100% power until an electrical failure in the supply to a reheater steam valve caused a 10%

derating. The electrical power was immediately restored and reactor power returned to 100%.

e On ^ March 26th, during a preplanned power descent necessary to repair a Feedwater Regulating Valve, a loss of both Main Feedwater Pumps necessitated -a' manual' trip of the reactor. The power output was approximately 200 MWe at the time of the occurrence. The Feedwater Regulating Valve was repaired and the reactor was restarted on March 27th. The unit remained at 100% power for the remainder of the month.
