Braidwood Unit 1 successfully returns to service

By Dorothy Davis

Exelon has reported that its Braidwood Nuclear Station Unit 1 has returned to service. Operators successfully connected the plant’s turbine generator to the regional grid  this morning at 5:43 a.m. CT.

Plant technicians have determined the cause of the automatic shut down Monday, September 20, to be a faulty electrical circuit card on one of the plant’s systems. The circuit card has been replaced.

Three Mile Island Nuclear Station, also owned and operated by Exelon, went offline Sunday due to a similar fault that also caused the plant’s turbine generator to automatically shut down. Service at Three Mile Island was restored late Monday night.

Service to customers in both incidences was not interrupted.

Braidwood’s two nuclear energy units can produce a total of more than 2,300 megawatts of electricity, enough to power more than 2 million homes.
