Fire reported, extinguished at Three Mile Island nuclear plant

The Exelon (NYSE:EXC) Three Mile Island nuclear plant in Pennsylvania experienced a fire at its auxiliary building Oct. 5, which evidently was quickly extinguished.

The unit continued to operate at 100% as of early Oct. 6, according to Nuclear Regulatory Commission (NRC) data.

At roughly 9:15 EDT an “alert” was declared due to a fire in the auxiliary building. “The licensee reported the fire was extinguished at approximately 2201 EDT. The fire did not hamper operations personnel responding to the fire. Offsite fire assistance was requested,” according to an event report filed with the NRC.

The small fire was extinguished by TMI firefighters and no help from outside fire companies was needed, according to a company news release. The small fire resulted from an overheated motor that circulates water to cool plant equipment, Exelon said.

The company notified fire and emergency officials and the Cumberland, Lebanon, Lancaster, York, and Dauphin, according to the NRC event report.

Three Mile Island is a roughly 800-MW pressurized water reactor (PWR) located in Dauphin County, Pa.
