"At 1253 [CST] Unit 2 Reactor was manually tripped due to a trip of both Main Feed Pumps. During an evolution to secure Circulating Water Pump 2-01, vacuum was reduced in the auxiliary condensers for both Main Feed Pumps causing both Main Feed Pumps to trip. Both Motor Driven and the Turbine Driven Auxiliary Feedwater Pumps started due to steam generator Lo-Lo levels. | |||
"Unit 2 is being maintained in Hot Standby (Mode 3) in accordance with Integrated Plant Operating Procedure IPO-0078. The Emergency Response Guideline Network has been exited. Decay heat is being rejected to the Main Condenser via the Steam Dump Valves." | |||
