Andras goal of Sustainability
As nuclear power assumes an increasingly important role in meeting the nation's requirements for electrical energy, the quantity of radioactive wastes will also increase. The wastes of primary concern -<br/>designated "high-level" and "alpha" wastes - contain radioactive nuclides that decay so slowly as to require that they be isolated from the biosphere for thousands of years.
Consideration of the technical feasibility of Yucca Mountain in Nevada as the site for a high-level nuclear<br/>waste repository has led to an intense debate regarding the economic, social, and political impacts of the<br/>repository.
Geologic repositories for radioactive waste are evolving<br/>from conceptualization to the development of specific<br/>designs. Estimates of long-term hazards must be based<br/>upon quantitative predictions of environmental releases<br/>over time periods of hundreds of thousands of years and<br/>longer.
After an exhaustive review process that encompassed EPAÕs proposed rule, as presented in the Federal Register Notice, as well as the reference materials cited in that Notice, Nevada concludes that EPAÕs proposed standard is inconsistent with the recommendations of the National Academy of Sciences (as required by the Energy Policy Act of 1992) and the July 9, 2004 ruling of the U.S. Circuit Court of Appeals for the District of Columbia.
The U.S. Nuclear Regulatory<br/>Commission (NRC) is proposing<br/>licensing criteria for disposal of spent<br/>nuclear fuel and high-level radioactive<br/>wastes in the proposed geologic<br/>repository at Yucca Mountain, Nevada.<br/>These criteria will address the<br/>performance of the repository system at<br/>Yucca Mountain, a system that must<br/>comprise both natural and engineered<br/>barriers.
Management of civilian radioactive waste has posed difficult issues for Congress since the beginning of the nuclear power industry in the 1950s. Federal policy is based on the premise that nuclear waste can be disposed of safely, but proposed storage and disposal facilities have frequently been challenged on safety, health, and environmental grounds.
The Nuclear Waste Management Organization (NWMO) is responsible for implementing Adaptive Phased Management (APM), Canada’s plan for the long-term care of the used nuclear fuel produced by Canada’s nuclear reactors.
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.

This report contributes to the InSOTEC research programme’s Work Package 1.1 that maps remaining socio-technical challenges to the implementation of geological disposal of radioactive waste across fourteen countries in the EU and North America (www.insotec.eu). The aim of this report is to provide an overview of the current situation of geological disposal of High Level radioactive Waste (HLW) and Spent Nuclear Fuel (SNF) in the USA.

News item from NEI summarizing siting process for nuclear waste repositories in Sweden, Finland and France.
News article on the history, status, and future use of the WIPP facility in New Mexico as a disposal site for spent nuclear fuel and high-level waste.
This Implementation Plan provides the scope, schedule, and funding needed to develop and implement a method for early evaluation of site suitability. The following is the sequence of events which resulted in the preparation of this implementation plan:<br/>1. On December 24, 1990, John W. Bartlett, Director of the Office of Civilian Radioactive Waste Management (OCRWM), transmitted guidance to Carl P. Gertz, Associate Director of the Office of Geologic Disposal (OGD), to develop an OGD Plan for this effort. <br/>2.
At the present time in Canada, high-level radioactive waste is accumulating in the form of irradiated, used fuel from research reactors and nuclear power generating stations. The used fuel bundles are kept in water-filled bays at each of the reactor sites. Because water is both a radiation barrier and an effective coolant, this system provides a safe means of storage. Used fuel is also safely stored above ground in dry concrete canisters in several Canadian locations.
The U.S. Nuclear Regulatory Commission (NRC) is amending its regulations governing the disposal of high-level radioactive wastes in a proposed geologic repository at Yucca Mountain, Nevada. The final rule implements the U.S. Environmental Protection Agency’s (EPA’s) revised standards for doses that could occur after 10,000 years, but within the period of geologic stability.
This country report on Canada contributes to the InSOTEC research programme’s Work Package 1.1 which maps remaining socio-technical challenges to the implementation of geological disposal of radioactive waste in fourteen countries in the EU and North America (www.insotec.eu). The aim of this country report is to provide an overview of the current situation of geological disposal of High Level radioactive Waste (HLW) and Spent Nuclear Fuel (SNF) in Canada.
Deep geologic repositories are being widely studied as the most favored method of disposal of nuclear waste. Scientists search for repository sites in salt, basalt, tuff and granite that are geologically and hydrologically suitable. The systematic evaluation of the safety and reliability of deep geologic disposal centers around the concept of interacting multiple barriers. The simplest element to describe of the geologic barrier is the physical isolation of the waste in a remote region at some depth within the rock unit.
The U.S. Department of Energy (DOE) has amended the policies under the Nuclear Waste Policy Act of 1982 for evaluating the suitability of Yucca Mountain, Nevada, as a site for development of a nuclear waste repository. The final rule at Title 10, Part 963 of the Code of Federal Regulations (10 CFR Part 963) focuses on the criteria and methodology to be used for evaluating relevant geological and other related aspects of the Yucca Mountain site.
The first worldwide review of geological problems in radioactive waste isolation was published by the Ernest Orlando Lawrence Berkeley National Laboratory (Berkeley Lab) in 1991 (Witherspoon, 1991). This review was a compilation of reports that had been submitted to a workshop held in conjunction with the 28th International Geological Congress that took place July 9Ð19, 1989, in Washington, D.C.
