Title | Plant Entered an Noue Due to the Loss of Off Site Power |
Event Description | The reactor scrammed from 100% power due to fluctuations occurring on the main generator and a loss of off site power. All rods fully inserted and all MSIV's closed. Reactor level is being maintained in the normal band of 173 to 214 inches using RCIC. Reactor pressure is being controlled via SRV's in lo-lo set mode between 905 and 1017 psig. Isolations occurred as expected for level 2 and level 3. HPCI and RCIC started on level 2 signal. HPCI has been shutdown but is available. All 4 EDG's started and loaded.
The NRC Resident Inspector was notified.
Unusual Event terminated at 1348 EDT on 08/15/03. R3DO (Sonia Burgess), NRR EO (Stu Richards) & FEMA (Bob Caldwell) notified. |
