Nuclear Regulatory Commission Accepts Luminant’s Nuclear Expansion Application

Dallas, TX -

Luminant announced today that the U.S. Nuclear Regulatory Commission (NRC) has docketed, or accepted for review, the company's application to expand its Comanche Peak nuclear facility. This determination indicates the application is complete and technically sufficient to allow the NRC to begin its comprehensive review.

"This is another significant step forward in our efforts to obtain a permit for safe, dependable and clean nuclear energy," said Luminant Executive Vice President and Chief Nuclear Officer Mike Blevins. "Our team accomplished its goal to submit a high-quality application and we look forward to providing additional information to the NRC throughout the review process."

Luminant submitted its application for a license to build and operate two US-Advanced Pressurized Water Reactors (US-APWR) at the Comanche Peak site on September 19. The NRC is also currently reviewing the US-APWR design from Mitsubishi Heavy Industries, Ltd (MHI) for certification. After an extensive evaluation of multiple prospective nuclear generating technologies, Luminant selected this design as its technology of choice. MHI submitted an application to have the US-APWR design certified by the NRC in December 2007.

MHI's U.S. subsidiary, Mitsubishi Nuclear Energy Systems Inc., assisted in the successful preparation of the COL application. Luminant and MHI continue to work toward the successful certification and licensing of US-APWR technology at Luminant's Comanche Peak site.
