Isolation in a geologic setting has been the generally favored solution to the high-level radioactive waste (HLW) problem since a scientific basis for nuclear waste management began to be formulated over half a century ago. Although general features of suitable settings have been enumerated, quantitative measures of the safety of geologic isolation of HLW are challenging to devise and to implement.
Congress designated Yucca Mountain, NV, as the nation’s sole candidate site for a permanent high-level nuclear waste repository in 1987, following years of controversy over the site-selection process. Over the strenuous objections of the State of Nevada, the Department of Energy (DOE) submitted a license application for the proposed Yucca Mountain repository in June 2008 to the Nuclear Regulatory Commission (NRC).
The U.S. Department of Energy (DOE) Yucca Mountain Site Characterization Project Office (YMPO) assigned Science Applications International Corporation (SAIC), the Technical and Management Support Services (T&MSS) contractor to the YMPO, the task of conducting an Early Site Suitability Evaluation (ESSE) of the Yucca Mountain site as a potential site for a high-level radioactive waste repository.
The U.S. Department of Energy is responding to the U.S. Nuclear Regulatory Commission staff's comments on the topical report, "Evaluation of the Potentially Adverse Condition 'Evidence of Extreme Erosion During the Quaternary Period' at Yucca Mountain, Nevada" and providing additional information supporting the conclusions reached in the report.
In this paper, the major elements of the site selection and characterization processes used in the U.S. high level waste program are discussed. While much of the evolution of the site selection and characterization processes have been driven by the unique nature of the U.S. program, these processes, which are well-defined and documented, could be used as an initial basis for developing site screening, selection, and characterization programs in other countries. Thus, this paper focuses more on the process elements than the specific details of the U.S. program.
This study evaluated the technical suitability of Yucca Mountain, Nevada, as a potential site for a mined geologic repository for the permanent disposal of radioactive waste. The evaluation was conducted primarily to determine early in the site characterization program if there are any features or conditions at the site that indicate it is unsuitable for repository development. A secondary purpose was to determine the status of<br/>knowledge in the major technical areas that affect the suitability of the site.

In response to your request, and as a follow-up to the ACNW Working Group meeting with you and your staff on June 17, 1992, we offer the following comments on the Early Site Suitability Evaluation (ESSE) for the proposed Yucca Mountain high-level waste repository site. Our comments relate both to the ESSE, as prepared by Science Applications International Corporation (SAIC), a contractor to the U.S. Department of Energy (DOE), and to the draft review prepared by your staff.
Current U.S. nuclear waste law and policy is bankrupt. The 1982 Nuclear Waste Policy Act (NWPA) set a 1998 deadline for opening a deep geologic repository to receive spent nuclear fuel (SNF) and high-level waste (HLW) from reprocessing. In 1987, Congress amended the Act to designate Yucca Mountain in Nevada as the only potential site, and severely restricted the development of any federal facility for consolidated storage of nuclear waste. Nevada’s unrelenting opposition to the Yucca repository eventually succeeded with the election of Barack Obama as President.
This appendix responds to the issues raised by Federal, State, and local governments, affected Indian Tribes, private citizens, and other organizations on the draft environmental assessment (EA) that was prepared pursuant to Section 112 of the Nuclear Waste Policy Act of 1982 (the Act). In addition to presenting the issues raised in the comments and the responses, it describes where changes were made in the final EA.
In February 1983, the U.S. Department of Energy (DOE) identified a reference repository location at the Hanford Site in Washington as one of the nine potentially acceptable sites for a mined geologic repository for spent nuclear fuel and high-level radioactive waste. The site is in the Columbia Plateau, which is one of five distinct geohydrologic settings considered for the first repository.
For more than half a century, since nuclear science helped us win World War II and ring in the Atomic Age, scientists have known that the Nation would need a secure, permanent facility in which to dispose of radioactive wastes. Twenty years ago, when Congress adopted the Nuclear Waste Policy Act of 1982 (NWPA or "the Act"), it recognized the overwhelming consensus in the scientific community that the best option for such a facility would be a deep underground repository.
By the end of this century, the United States plans to begin operating the first geologic repository for the permanent disposal of commercial spent nuclear fuel and high-level radioactive Waste. Public Law 97-425, the Nuclear waste Policy Act of 1982 (the Act), specifies the process for selecting a repository site, and constructing, operating, closing, and decommissioning the repository.
In 2001, as directed by the Energy Policy Act of 1992, the U.S. Environmental Protection Agency (EPA) issued public health and environmental radiation protection standards for the proposed repository at Yucca Mountain, Nevada. Several parties sued the Agency on a myriad of aspects of the rule. The Court ruled in EPA’s favor in all aspects of the case but one, and returned the standards to the Agency in 2004. In 2005, EPA proposed amendments to the standards. Following public hearings and a public review period, the final amendments were issued in September 2008.
