Athens, AL – A unit at the Browns Ferry nuclear power plant remained shut down on Tuesday, two days after workers noticed its electricity generator was vibrating more than usual.
The Tennessee Valley Authority, the nation's largest public utility, owns the plant.
TVA spokesman Ray Golden says operators noticed the vibration at the turbine of the plant's third unit and lowered the output of the nuclear reactor. When the vibrating continued, the workers shut down the unit.
This year, Browns Ferry has had two other unplanned shutdowns because of technical issues. Golden says TVA shut down Unit 2 from June 9-11 and Unit 3 from Aug. 12-18.
Golden says there's no word on when the unit will return to service.
