Nuclear power unit removed from service for maintenance

Southern Co. (NYSE: SO) said plant operators on Feb. 13 safely took Unit 1 of the 1,848 MW Edwin I. Hatch Nuclear Plant offline for a scheduled refueling and maintenance outage. The last refueling outage for the 924 MW Unit 1 was completed in spring 2010.

Each unit at Plant Hatch requires refueling every 24 months. Aside from refueling the reactor and performing regular maintenance and testing, workers also will replace the Main Turbine Low Pressure Rotor.

Plant Hatch Unit 2 will continue to generate electricity while Unit 1 is offline and refueling.

Unit 1 began commercial operation in December 1975 while Unit 2 began commercial operation in September 1979.
