Topical Report - Evaluation of the Potentially Adverse Condition "Evidence of Extreme Erosion During the Quaternary Period" at Yucca Mountain, Nevada
The potentially adverse condition identified at 10 CFR 60.122(c)(16), evidence of extreme<br/>erosion during the Quaternary Period, has been determined to not be present at Yucca<br/>Mountain. A literature search for typical hillslope erosion rates in the U.S. and the world was<br/>performed to establish a range of typical values for erosion rates. Low to moderate erosion<br/>rates in the U.S. were identified to range from 2 to 50 centimeters per thousand years (cm/ka)<br/>in semiarid environments.

Locating a radioactive waste repository in the ring of fire
Locating a radioactive waste repository in the ring of fire
The scientific, technical, and sociopolitical challenges of finding a secure site for a geological repository for radioactive wastes have created a long and stony path for many countries. Japan carried out many years of research and development before taking its first steps in site selection.
Management of Uncertainty in Safety Cases and the Role of Risk - Workshop Proceedings
Management of Uncertainty in Safety Cases and the Role of Risk - Workshop Proceedings
The development of radioactive waste repositories involves consideration of how the waste and the
engineered barrier systems will evolve, as well as the interactions between these and, often relatively
complex, natural systems. The timescales that must be considered are much longer than the timescales
that can be studied in the laboratory or during site characterisation. These and other factors can lead to
various types of uncertainty (on scenarios, models and parameters) in the assessment of long-term,

H12: Project to Establish the Scientific and Technical Basis for HLW Disposal in Japan Project Overview Report
As outlined in the overall program for high-level waste (HLW) management in Japan, defined by the Atomic Energy Commission (AEC), HWL separated from spent nuclear fuel during reprocessing will be immobilized in a glass matrix and stored for a period of 30 to 50 years to allow cooling; it will then be disposed of in a stable deep geological formation.
History, Structure and Institutional Overview of the Nuclear Waste Policy Act of 1982
History, Structure and Institutional Overview of the Nuclear Waste Policy Act of 1982
The Nuclear Waste Policy Act of 1982 (NWPA) established a program to deal comprehensively with the waste byproducts of nuclear power generation, as well as defense-related radioactive wastes, if appropriate. Under this program, the federal Department of Energy (DOE) must locate and develop a site for disposal of high-level radioactive wastes in a geologic setting capable of isolating them from adverse public and environmental exposure for at least 10,000 and up to 100,000 years.
Evaluating Site Suitability for a HLW Repository
Evaluating Site Suitability for a HLW Repository
The primary objective of government policy, and of NUMO in implementing this policy, is to
ensure that a repository for Japan’s high-level radioactive waste is located so as to provide
secure isolation of the waste and adequate safety for present and future generations. This
means that the site has to be chosen carefully, taking full account of all its characteristics. In
order to address these characteristics in an orderly and structured manner, we have established

EPRI Review of Geologic Disposal for Used Fuel and High Level Radioactive Waste: Volume IV - Lessons Learned
The effective termination of the Yucca Mountain program by the U.S. Administration in 2009 has further delayed the construction and operation of a permanent disposal facility for used fuel and high level radioactive waste (HLW) in the United States. In concert with this decision, the President directed the Energy Secretary to establish the Blue Ribbon Commission on America's Nuclear Future to review and provide recommendations on options for managing used fuel and HLW.

Evaluation of a Spent Fuel Repository at Yucca Mountain, Nevada
Evaluation of a Spent Fuel Repository at Yucca Mountain, Nevada
In June 2008, the U.S. Department of Energy (DOE) submitted a license application to the U.S. Nuclear Regulatory Commission (NRC) for the construction of a geologic repository at Yucca Mountain, Nevada, for the disposal of spent nuclear fuel and high-level radioactive waste. The license application was accepted for formal NRC review in September 2008. Throughout the more than 20-year history of the Yucca Mountain project, EPRI has performed independent assessments of key technical and scientific issues to facilitate an understanding of overall repository performance.
Criticality Risks During Transportation of Spent Nuclear Fuel
Criticality Risks During Transportation of Spent Nuclear Fuel
This report presents a best-estimate probabilistic risk assessment (PRA) to quantify the frequency of criticality accidents during railroad transportation of spent nuclear fuel casks. The assessment is of sufficient detail to enable full scrutiny of the model logic and the basis for each quantitative parameter contributing to criticality accident scenario frequencies. The report takes into account the results of a 2007 peer review of the initial version of this probabilistic risk assessment, which was published as EPRI Technical Report 1013449 in December 2006.
An Updated Perspective on the US Nuclear Fuel Cycle
An Updated Perspective on the US Nuclear Fuel Cycle
There has been a resurgence of interest in the possibility of processing the US spent nuclear fuel, instead of burying it in a geologic repository. Accordingly, key topical findings from three relevant EPRI evaluations made in the 1990-1995 timeframe are recapped and updated to accommodate a few developments over the subsequent ten years. Views recently expressed by other US entities are discussed.

Consolidated Interim Storage of Commercial Spent Nuclear Fuel
Consolidated Interim Storage of Commercial Spent Nuclear Fuel
Approximately 54,000 tons of spent nuclear fuel are stored at operating nuclear power
plants and several decommissioned power plants throughout the country. Spent fuel
storage at these sites was never intended to be permanent. The current Federal plan is to
place the fuel in a repository for permanent disposal in Nevada at Yucca Mountain.
Recently, appropriations committees in Congress suggested building one or more Federal
sites for consolidated interim storage of spent fuel. Several reasons were identified. The

Yucca Mountain - Nevada's Perspective
Yucca Mountain - Nevada's Perspective
Yucca Mountain—that barren rise in the desert ninety miles from Las Vegas—is the nation‘s only site identified for the potential location of the first ge ological repository for commercially-generated HLNW and SNF. Many assume
that Yucca Mountain has geologic and climatic qualities that make it uniquely
suitable to isolate the thousands of metric tons of the world‘s most lethal, long lived waste currently accumulating at 104 operating nuclear power plants across the United States.
Unfortunately, Yucca Mountain is an exceptionally bad site,

EPRI Review of Geologic Disposal for Used Fuel and High Level Radioactive Waste Volume I—The U.S. Site Selection Process Prior to the Nuclear Waste Policy Amendments Act
U.S. efforts to site and construct a deep geologic repository for used fuel and high level radioactive waste (HLW) proceeded in fits and starts over a three decade period from the late 1950s until 1982, when the U.S. Congress enacted the Nuclear Waste Policy Act (NWPA). This legislation codified a national approach for developing a deep geologic repository. Amendment of the NWPA in 1987 resulted in a number of dramatic changes in direction for the U.S. program, most notably the selection of Yucca Mountain as the only site of the three remaining candidates for continued investigation.
