CORDOVA, Ill. -Operators returned Quad Cities Generating Station Unit 1 to full power Wednesday, marking the successful conclusion of the station's 22nd scheduled refueling outage.
Quad Cities Station Unit 1 was taken off line on Monday, March 11. The refuel outage was completed in 28 days.
During the outage, Exelon employees and highly skilled supplemental workers performed more than 12,000 activities, including extensive safety inspections and tests, along with numerous plant improvements.
Workers replaced one-third of the reactor's fuel, performed preventive maintenance activities and performed walkdowns and inspections of valves and power supply systems that could be needed in response to an earthquake or flood.
All the work and inspections are designed to enhance the Quad Cities Station's layers upon layers of operational strength and to ensure the facility's ability to provide clean, safe and reliable electricity for another two-year operating cycle.
"It takes a great deal of coordination and hard work to successfully disassemble, inspect, test and reassemble the reactor and associated equipment to ensure that this unit continues operating in a safe and reliable manner throughout the next operating cycle," said Tim Hanley, Quad Cities Station site vice president.
More than 2,000 skilled workers from local union halls and technical experts from other Exelon Generation facilities supported Quad Cities' employees during the refueling outage.
Quad Cities Unit 2 continued to operate at full power during the Unit 1 outage.
Quad Cities Generating Station is located three miles north of Cordova, Ill. At full power, the facility's two generating units produce more than 2,200 megawatts around the clock, enough electricity for more than one million typical homes.
