Ameren Missouri’s Callaway Energy Center finished its 22nd planned refueling and maintenance outage today and has returned to power operations. During the outage, one-third of Callaway's 193 fuel assemblies were replaced. The largest overall job was a complete overhaul of the main generator stator assembly.
"We finished a list of more than 10,000 tasks, returning the supply of safe, reliable and carbon-free nuclear energy to the community," said Barry Cox, senior director of nuclear operations.
With so many tasks to complete, Ameren Missouri added approximately 1,000 additional workers from across the state to finish the work during the outage window. They supplemented Callaway's regular workforce of about 800 employees.
"While the outage was longer than normal refueling outages, our co-workers take pride in ensuring work is done safely and correctly," Cox added. "At Ameren Missouri, we never compromise on safety. The most important accomplishment is that the work was completed safely."
Work accomplished during the outage will ensure Callaway's long-term health. It is licensed to operate through 2044. Prior to the planned outage, Cox says Callaway had a continuous run of 514 days, which is among the longest in the Energy Center's 33-year history.
The Callaway Energy Center typically generates 20 percent of the electricity for Ameren Missouri’s 1.2 million customers. Callaway's next refueling outage is scheduled for spring 2019.
