The reactor at the Fermi 2 nuclear power plant in Frenchtown Township, Michigan, restarted after a refueling and maintenance shutdown.

A manual shutdown took place Sept. 13 due to a problem with a system used to cool auxiliary equipment at the plant along Lake Erie in Monroe County, said DTE Energy Co. officials.

As a result, an already planned refueling and maintenance outage moved up due to the shutdown.

Utility spokesman Guy Cerullo said the plant synchronized with Detroit-based DTE’s electrical grid last Sunday.

At the time of the Sept. 13 incident, Cerullo said the plant’s cooling system “essentially stopped working.”

The cooling system cools auxiliary equipment and when the system is not available to do so, operations staff manually shut down the plant. A plant also can automatically shut down when equipment malfunctions. The last automatic shutdown took place March 19.

The plant had been operational for 163 days without a shutdown until Sept. 13.
