A fire briefly ignited during testing of an emergency diesel generator Thursday at the Fermi nuclear plant near Toledo, Ohio.
The DTE Energy plant was shut down for refueling when it declared an alert at 2:05 p.m. because the fire affected safety equipment. According to a report filed with the Nuclear Regulatory Commission, oil-soaked lagging around a generator's turbocharger caught fire. Plant staff quickly put it out with a handheld extinguisher, and the alert declaration ended at 3:32 p.m.
Fermi reported that damage was limited to the insulation that caught fire while the generator was running. The incident did not result in any injuries, according to a DTE release, and the reactor has been stable since it was shut down on Feb. 10 for a planned outage.
The NRC said it was reviewing the circumstances surrounding the fire. The plant is a 1,122 megawatt General Electric type 4 boiling water reactor first licensed in 1985.
