Title	Rps Actuation Due to Loss of Offsite Power
Event Description	On August 14, 2004, at approximately 1259 hours0.0146 days <br />0.35 hours <br />0.00208 weeks <br />4.790495e-4 months <br /> [EDT], the unit scrammed due to a loss of offsite power. The cause of the loss of power has not been determined at this time. The four emergency diesel generators started as required and properly aligned to the emergency buses. All control rods properly inserted. The initial safety significance of this condition is considered to be minimal. All safety systems function properly with the exception of 1 B Standby Gas Train. The 1 B Standby Gas Train tripped due to an overheat condition. Safety significance of this failure is minimal since the 1A Standby Gas Train operated properly and Reactor Building Ventilation System isolated. The plant is in a stable condition. Troubleshooting activities are in progress to determine the cause of the event and corrective actions. Received Group II, VI, and VIII PCIS isolations due to the loss of power. The MSIVs are closed and the licensee manually started RCIC for reactor level control and HPCI for reactor pressure control. The licensee notified the NRC Resident Inspector.
