 Faulty Fire Detector Causes LaSalle Station to Declare, Terminate Unusual Event 

 Operators at LaSalle County Generating Station declared an “usual event” at 8:12 a.m. (CDT) today due to a faulty fire alarm that activated. The event was terminated within an hour.  

  

MARSEILLES, Ill. (August 25, 2014) -- Operators at LaSalle County Generating Station declared an “usual event” at 8:12 a.m. (CDT) today due to a faulty fire alarm that activated. The event was terminated within an hour.

Operators verified that there was no fire and deactivated the alarm within 20 minutes. The station is replacing the fire detector. Both units continue to operate at full power.

Nuclear Regulatory Commission (NRC) regulations require operators to terminate a fire alarm within 15 minutes or designate the activation of an “unusual event.”

An unusual event is the lowest emergency level in the NRC’s emergency classification system. Station personnel notified all appropriate federal, state and local government officials.

LaSalle Generating Station is located about 75 miles southwest of Chicago, near Marseilles, Ill. At full power, the facility’s two units produce more than 2,200 megawatts of carbon free electricity, enough to power 2.3 million homes.
