ATHENS, Ala. (AP) -- The Tennessee Valley Authority says it is unsure when repairs will be completed on its Browns Ferry Nuclear Plant Unit 3 reactor.
The unit has been shut down since Dec. 31 because of a problem with an electrical generator.
TVA spokesman Gil Francis says the work shouldn't take long, but the top priority is safety.
A Nuclear Regulatory Commission report shows the reactor shut down on New Year's Eve because of a signal that indicated a problem with the generator.
Unit 3 produces enough power for about 650,000 homes.
August shutdowns forced TVA to purchase high-priced power produced by natural gas turbines, but lower demands in winter should make rate increases unlikely.
