CORDOVA, Ill. (AP) — Operators of the Quad Cities Generating Station in western Illinois declared an "alert" after smoke was observed in a plant electrical system.
Exelon Generation spokesman William Stoermer says Exelon's technical experts are looking into the cause of the smoke. According to Stoermer, Quad Cities Unit 2 was removed from service on Monday to replace a valve on the control rod drive system. The unit was in the startup process Wednesday when smoke was detected. The unit is stable and shut down. Unit 1 remains at full power.
The U.S. Nuclear Regulatory Commission says there have been no abnormal releases of radioactive material as a result of the event at the plant. Agency officials say fire equipment and ambulances were summoned to site as a precaution. There were no injuries.
