| Title | Reactor Trip Due to Turbine Trip as a Result of Failed Power Supply |
| Event Description | Ginna Station received a reactor trip from Turbine Trip at 2112 hrs on 02/16/05. The Turbine Trip signal was generated from the ATWS Mitigation System Actuation Circuitry (AMSAC) related to a failed power supply in the Advanced Digital Feedwater Control System. All control rods inserted on the reactor trip. The plant is currently stable in Mode 3, RCS Pressure 2235 psig, Temperature 540 deg F. AFW [Auxiliary Feed Water] did actuate as designed after the trip.
For the transient, min & max Temperatures, Pressures & Levels are: RCS Temperature: Max - 561 deg F Min - 538 deg F RCS Pressure: Max - 2250 psig Min - 2218 psig Pressurizer Level: Max - 50% Min - 28% The electrical grid is stable. Decay heat is being rejected to the Main Condenser. The licensee notified the NRC Resident Inspector and the State Public Service Commission. |
