MONROE, Mich. (AP) — The Nuclear Regulatory Commission will investigate a small fire that burned insulation for an emergency generator at the Fermi 2 nuclear power plant in southeastern Michigan.
The owner, DTE Energy, says the fire occurred Thursday during routine testing and was quickly extinguished. The fire was near an air intake system on one of the station's four diesel generators.
No one was injured, and the NRC says no radiation was released. An alert was issued and remained in effect for almost 90 minutes. The alert is the second-lowest emergency level in the commission's emergency classification system.
The Fermi plant has been shut down since Feb. 10 for refueling and maintenance.
