Event Report: Safety systems switch on unexpectedly at Comanche Peak

The Comanche Peak nuclear power plant in North Texas told the Nuclear Regulatory Commission that its Unit 1 reactor had an unexpected activation of two of its emergency systems yesterday afternoon. Plant officials said that the reactor’s Blackout Sequencer faulted, resulting in activation of the unit’s Turbine Driven Auxiliary Feed Water Pump and its Train ‘B’ Emergency Diesel Generator. Operators reduced power to 97 per cent of rated power following the incident. Investigation of the cause of the activations is ongoing.
