DOE Submits Application for Yucca Mountain Nuclear Waste Repository to NRC

LCG, June 4, 2008--The U.S. Department of Energy (DOE) submitted an application to the Nuclear Regulatory Commission (NRC) for a license to construct the country's first underground, geologic repository for spent nuclear fuel and high-level nuclear waste at Yucca Mountain, Nevada. The application is over 8,600 pages long, plus approximately 200 other supporting documents, including a Final Environmental Impact Statement (FEIS).

Nuclear wastes are now stored at 121 temporary locations in 39 states. In 2002 Congress and the President approved Yucca Mountain to be the site for the country's first permanent geologic repository for spent nuclear fuel and high-level radioactive waste. With the application submitted, the NRC will determine whether the application is sufficiently complete. If deemed complete, the NRC will formally docket the application and publish a notice of opportunity to request a hearing before the NRC?s Atomic Safety and Licensing Board. In addition, the NRC will announce the extent to which it will adopt the DOE?s FEIS for the proposed repository, located approximately ninety miles northwest of Las Vegas in the Mojave Desert.

After the NRC formally dockets the application, the NRC will follow a prescribed, three-year schedule to decide if construction should be authorized. The NRC may request a one-year extension, and the NRC has stated it expects it will need the extension.

To address the myriad of scientific environmental and engineering issues, the NRC plans to utilize a team of over one hundred contractors and staff employees, including staff at the NRC?s headquarters in Rockville, Maryland, the Region IV office in Arlington, Texas, and the NRC?s Las Vegas office. Further technical support will be provided by the Center for Nuclear Waste Regulatory Analysis in San Antonio, Texas, a federally funded research and development center.
