CARLTON, Wis. – Kewaunee Power Station was manually shut down Wednesday night after a feedwater pump on the non-nuclear side of the station shut off.

The unit was in the process of being shut down and was at 35 percent power at the time of the event. It remained in a safe condition throughout.

The unit was being shut down so a small leak in a service water line on the non-nuclear side of the station could be repaired.

As a conservative measure, the station declared an alert shortly before 9 p.m. and federal and state officials were notified. An alert is the next to least serious of four emergency categories in the Nuclear Regulatory Commission's rating system. The alert ended about 12:25 a.m. Central Time.

No release of radioactive material occurred beyond normal, minor releases associated with routine plant operations. There was no danger to the public or plant workers.

A feedwater pump supplies water to the steam generator for steam production to run the turbine generator, which generates electricity.
