Operators at Exelon’s Quad Cities Generating Station Unit 2 nuclear reactor have terminated an alert declared after smoke was detected in one of the plant’s electrical systems.

Exelon (NYSE: EXC) operators terminated an alert  Wednesday at 9:32 p.m. CDT for Quad Cities Generating Station Unit 2.

Station operators declared the alert at 1:40 p.m. CDT due to smoke observed in one of the nuclear power plant’s electrical systems. The smoke occurred when a pipe released water onto an electrical system, causing an electrical fault. The plant remains stable and Unit 1 continues to operate.

The facility’s equipment operated as expected in response to the event. There was no impact to public health or safety or to plant personnel.

Quad Cities Unit 2 was returning to service from a maintenance outage when the event occurred. 

An alert is the second lowest of four emergency classifications established by the U.S. Nuclear Regulatory Commission (NRC).

Quad Cities Station is located approximately 20 miles northeast of Moline, Ill. With both units running at full power, Quad Cities generates enough electricity to power approximately 1 million average American homes.
