The Nuclear Regulatory Commission has approved two proposed new nuclear power reactors at Southern Nuclear’s Vogtle site in Georgia. The move marks the first time the NRC has approved new reactors in the United States since 1978, shortly before the Three Mile Island nuclear meltdown in Pennsylvania. The vote was four to one, with NRC Chair Gregory Jaczko casting the sole dissenting vote. Jaczko said he had objected to the licenses over the absence of guarantees to implement recommendations made following the Fukushima nuclear disaster in Japan last year. A coalition of anti-nuclear groups has vowed to file suit in order to block the project.
