The Tennessee Valley Authority plans to add around 100 jobs at its Browns Ferry Nuclear Plant in the next year. The plan, announced Wednesday, is part of an effort to improve performance and safety. TVA chief nuclear officer Preston Swafford says officials will probably start the hiring process in a couple of months. Keith Polson, Browns Ferry site vice president, says the new jobs will involve various specialties such as engineering, maintenance, radiation protection, chemistry, work control and emergency planning. / Tennessee Valley Authority

Federal regulators have issued a violation to the Tennessee Valley Authority after an inspection at its Browns Ferry nuclear power plant in northern Alabama. The Nuclear Regulatory Commission said in a statement that its staff will increase oversight at the facility. The agency said the "white" finding for all three of the facility's units comes after NRC inspectors found that plant operators and employees were unable to adequately perform newly implemented procedures for a safe plant shutdown. The NRC said it determined that workers were not adequately trained on the new procedures.
