Yesterday, I told you that Unit 1 at the Comanche Peak nuclear power plant in north Texas experienced an unexpected activation of the reactor’s emergency systems. Despite the problems, the plant continued to operate the reactor at 100 per cent of rated power.
Early this morning, the situation got worse. Operators were forced to manually scram the reactor due to rising temperatures in a bearing in a coolant pump.
The reactor is now shut down and investigation of the cause of both incidents is ongoing.
