Refueling and maintenance activities at Ameren Missouri’s Callaway Energy Center are complete, and the 1,190-megawatt nuclear plant is back in service. This was the 21st planned refueling and maintenance outage for Callaway.
During the refueling period, which began April 2nd, thousands of periodic maintenance activities, inspections and tests were performed to maintain and monitor the integrity of plant. The refueling activities, which occur every 18 months, replaced 92 of the 193 fuel assemblies in the reactor core. Each fuel assembly is an 8½-inch square bundle of 12-foot long metal tubes containing ceramic pellets of uranium dioxide fuel.
To help accomplish the wide range of tasks, more than 1,000 supplemental workers joined Callaway’s regular workforce of about 800 employees – providing a powerful boost to the area’s economy.
“Our refueling outages are successful because of the dedication and teamwork of Ameren's co-workers and our supplemental staff. Their on-going efforts ensure that equipment integrity is maintained and that Callaway will continue to be a reliable source of energy for our state,” said Barry Cox, Sr. Director of Nuclear Operations.
