Ameren Missouri completes refueling, maintenance outage of Callaway Energy Center

Ameren Missouri announced Wednesday that workers completed the 22nd planned refueling and maintenance outage at the Callaway Energy Center and resumed power operations.

During the outage, Ameren replaced one-third of the facility’s 193 fuel assemblies and completed an 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,” Barry Cox, senior director of nuclear operations, said.

The company supplemented their workforce of approximately 800 with an additional approximately 1,000 workers to complete the outage.

While the outage was longer than normal refueling outages, our co-workers take pride in ensuring work is done safely and correctly,” Cox said. “At Ameren Missouri, we never compromise on safety. The most important accomplishment is that the work was completed safely.”

Prior to the planned outage, Callaway ran for 514 continuous days. The facility is licensed to operate through 2044.
