Ameren Missouri (NYSE: AEE) shut down the 1,190-MW Callaway Energy Center in Missouri for a planned refueling and maintenance outage that also includes installation of a new nuclear reactor vessel head.
The reactor was shut down Oct. 11 and will be out of service for several weeks. During the outage, workers will replace 84 of the 193 fuel assemblies in the reactor core along with thousands of maintenance activities, inspections and tests. The $150 million reactor vessel head will replace the one that went online with the plant in 1984.
More than 1,100 supplemental workers will join Callaway’s regular workforce of about 800 employees during the outage.
