An alert imposed after smoke was spotted at the Quad Cities Generating Station in western Illinois was lifted after eight hours.  

Exelon Generation officials say the smoke was spotted Wednesday after a pipe released water onto an electrical system.  
Spokesman William Stoermer says Quad Cities Unit 2 had been removed from service Monday so workers could replace a valve. The unit was in being restarted when smoke was detected around 1:40 p.m. The alert was lifted around 9:30 p.m.  

Illinois’ largest energy producer, Exelon, generated a buzz in April when the company revealed it is studying the feasibility of building a nuclear reactor in the small downstate community of Clinton.

Such a proposal would have been unheard of in Illinois just five years ago. That’s when Exelon’s corporate predecessor, Commonwealth Edison, was a lightning rod for worries about its poor safety record and inefficient production.
