Donald C. Cook nuclear plant officials said a planned refueling and maintenance outage just started for its Unit 1 reactor in Bridgman, MI.

In preparation for the outage, the reactor ended up reduced to 50 percent power Saturday, and the plan called for shutting down the reactor this past Tuesday night, plant spokesman Bill Schalk said.

The outage comes at a time when the plant recently set a record for its capacity since the last outage, which ended in the spring of 2013, Schalk said. The reactor’s output remained connected to the electric grid for 15 consecutive months, and the plant achieved record electrical capacity during that time, he said.

An estimated 2,500 contracted workers will work at the plant during the outage, augmenting the plant’s regular 1,198 employees, Schalk said.

A special maintenance job will be replacement of the reactor’s two 58-ton feedwater heaters, used to heat water before it enters the steam generators, he said.

Indiana Michigan Power, a wholly owned subsidiary of American Electric Power, owns and operates the plant.
