Fermi nuclear unit shut down after switchyard power loss

The 1,140 MW Unit 2 at the Fermi nuclear power plant in Michigan automatically shut down Sept. 14 after the onsite power loss from a 120 kV switchyard.

All of the backup functions performed as expected and the control rods were fully inserted into the reactor.

The plant is owned by Detroit Edison, a unit of DTE Energy (NYSE: DTE). Unit 2 is a GE (NYSE: GE) Type 4 Mark I boiling water reactor.

There is no word on when the unit will be returned to service.
