Michigan reactor shut down as a result of maintenance error

Sunday afternoon, a worker performing maintenance at the Palisades nuclear plant in Michigan dropped a bus bar and caused an arc in an electrical panel. “The loss of both preferred AC busses caused a reactor trip, a safety injection signal, auxiliary feedwater actuation signal, containment high radiation isolation signal, and main steam isolation signal” according to this morning’s NRC Event Reports.

The reactor is currently in Hot Standby and is controlling temperature using atmospheric dump valves. Palisades reports that all power systems have now been restored, but the plant is still at 0 per cent output while investigations continue.
