| Title | Automatic Start of the Emergency Diesel Generator and Loss of Radiation Monitor |
| Event Description | RCS [Reactor Coolant System] Pressure: vented to containment, refueling cavity greater than 23ft. [above reactor vessel]. RCS temperature: 96 degrees Fahrenheit.
The 12A bus de-energized, 'A' EDG [Emergency Diesel Generator] automatically started and loaded on [emergency] buses 14 and 18. The RCS configuration is refueling cavity level greater than 23ft. above the reactor flange with no impact to shutdown cooling. Radiation monitor R-1, Control Room radiation monitor, lost power for 2 hrs 10 min. This placed Ginna in a major loss of emergency preparedness capabilities. A temporary radiation monitor has been installed in the Control Room. Prior to the notification, the licensee had restored the 12A bus from offsite power and the R-1 monitor was re-energized. The licensee notified the NRC Resident Inspector. |
