Siting of a proposed high-level nuclear waste repository at the Yucca Mountain, Nevada was federally approved in 2002, and a license application for construction will be submitted from U. S. Department of Energy to U. S. Nuclear Regulatory Commission in 2005, according to the federal regulation of 10 CFR Part 63. U. S. Nuclear Regulatory Commission will strictly review the license application, according to the process and schedule of the federal regulation of 10 CFR Part 2. When NRC judges that contents of the license application and its revised version assure the public health and safety before and after permanent closure of the repository, U. S. Nuclear Regulatory Commission authorizes the construction of the repository and issue the license for its operation.
