mdsolar writes in with news that plans to build two new reactors at the Comanche Peak nuclear power plant have been put on hold. "On Friday, Luminant, a subsidiary of Dallas-based Energy Future Holdings, suspended its application to the U.S. Nuclear Regulatory Commission to build two new reactors at the plant. Its partner on the project, Mitsubishi Heavy Industries, said it was focusing on getting its nuclear reactors in Japan back in operation. The majority of Japan's reactors were shut down because of safety concerns following a 2011 tsunami that caused a radiation leak at the Fukushima Daiichi nuclear complex 150 miles north of Tokyo. Mitsubishi 'has informed us that they will materially slow the development of their design control document for their new reactor design by several years. In addition, both [Mitsubishi] and Luminant understand the current economic reality of low Texas power prices driven in large part by the boom in natural gas,' read a statement from Luminant."
