00:00:13 The Electromatic Relief (RC-RV2) solenoid de-energized giving (0400:50) Approximate a non-open indication to the control room operators. The Elec- tromatic Relief Valve (RC-RV2) should have reseated at about this time (closure setpoint of 2205 psig). 00:00:14 The Emergency Feed Pumps (EF-P1, 2A and 2B) achieved normal dis- (0400:51) charge pressure. 00:00:15 Water hammer in the condensate piping occurred. (0400:52) Approximate 00:00:30 Pressurizer Safety Valve (RC-RV1B) and Electromatic Relief Valve (0401:07) (RC-RV2) discharge line temperature alarms printed out. 00:00:38 Steam Generator A level reached the 30-inch setpoint where the (0401:15) Approximate Emergency Feedwater Valves (EF-V11A and EF-V11B) open. Feedwater was not admitted because emergency feedwater Block Valves (EF-V12A and EF-V12B) were shut. 00:00:39 Reactor Coolant Makeup Pump A (MU-P-1A) was stopped. (0401:16) 00:00:40 Steam Generator B level reached the 30-inch setpoint where the (0401:17) Approximate Emergency Feedwater Valves (EF-V11A and EF-V11B) open. Feedwater was not admitted because Emergency Feedwater Block Valves (EF-V12A and EF-V12B) were shut. 00:00:41 Reactor Coolant Makeup Pump A (MU-P-1A) was restarted. With (0401:18) Reactor Coolant Makeup Pumps A and B (MU-P-1A and MU-P-1B) oper- ating, pressurizer level rate of decrease slowed.- 3 -
