REACTOR TRIP FROM 100% POWER DUE TO DECREASING STEAM GENERATOR WATER LEVELS

During 100% power operation of Unit 2, the Reactor Protection System (RPS) properly initiated an automatic Reactor Scram signal in response to decreasing Steam Generator (S/G) water levels. Steam Generator
water levels were decreasing due to an 'A' Main Feedwater Pump trip, which in turn had been caused by an 'A'
Condensate Pump trip. All rods fully inserted into the core, and all Safety Systems operated as designed. The
cause of the Condensate Pump trip is not currently known, and investigation is continuing. No Radiological Releases, RCS leaks, or S/G leaks occurred during this event.

The NRC Resident Inspector was notified.
