MANUAL REACTOR TRIP DUE TO LOSS OF FEEDWATER
"Manual reactor trip due to falling level in 1A Steam Generator (S/G), (RPS Activation). Level decrease occurred after the Feedwater Regulating Valve (FRV) for the 1A S/G failed closed upon loss of the normal and backup electrical power to the valve solenoid. After the reactor trip, the 1A S/G experienced a LO-LO Level Alarm which auto started both motor driven Auxiliary Feedwater pumps, (ESF Actuation). All S/G levels are now at normal levels and Unit 1 is stable. An investigation is in progress to determine the loss of electrical power to the FRV solenoid for the 1A S/G."
The plant is dumping steam to the Main Condenser with no known Primary/Secondary leakage. There was no actuation of primary safety valves. All safety systems are operable and normal electrical distribution is available.
The NRC Resident Inspector has been notified.

UNUSUAL EVENT DUE TO UNCONTROLLED FLAMMABLE GAS LEAK ONSITE
At 0946 CST, 3/4/02, an Unusual Event was declared due to a non isolable leak on a propane tank. The tank is approximately 500 to 750 gals, and is 55 % full. The tank is leaking at the rate of 5% decrease every 20 minutes. The tank is 25 to 30 yards out in the Owner Controlled Area and a local area evacuation has been performed. The Two Creek Fire Department is on the scene.
NRC Resident Inspector has been notified.
At 1147 EST, NRC entered Monitoring for Normal Phase Mode.
***EVENT UPDATED AT 1309 EST ON 3/4/02 BY MARK HANSON TO FANGIE JONES***
At 1154 CST, Licensee terminated Unusual Event due to leak isolated.
At 1310 EST, NRC exited monitoring for the Unusual Event.
Notified IRO (Holonich), R3DO (Madera), NRR (Grimes), PAO (Dricks), FEMA (Snyder).
