During the next several years, decisions are expected to be made in several countries on the further development and implementation of the geological disposition option. The Board on Radioactive Waste Management (BRWM) of the U.S. National Academies believes that informed and reasoned discussion of relevant scientific, engineering and social issues can-and should-play a constructive role in the decision process by providing information to decision makers on relevant technical and policy issues. A BRWM-initiated project including a workshop at Irvine, California on November 4-5, 1999, and subsequent National Academies' report to be published in spring, 2000, are intended to provide such information to national policy makers both in the U.S. and abroad. To inform national policies, it is essential that experts from the physical, geological, and engineering sciences, and experts from the policy and social science communities work together. Some national programs have involved social science and policy experts from the beginning, while other programs have only recently recognized the importance of this collaboration. An important goal of the November workshop is to facilitate dialogue between these communities, as well as to encourage the sharing of experiences from many national programs. The workshop steering committee has prepared this discussion for participants at the workshop. It should elicit critical comments and help identify topics requiring in-depth discussion at the workshop. It is not intended as a statement of findings, conclusions, or recommendations. It is rather intended as a vehicle for stimulating dialogue among the workshop participants. Out of that dialogue will emerge the findings, conclusions, and recommendations of the National Academies' report.

Time is both the ally of high-level nuclear waste (HLNW) managers and the enemy. It is the ally because the radioactivity in elements and isotopes decreases with age, making the waste progressively less dangerous to human health and safety and the environment. This rate of radioactive decline varies, in some cases diminishing by half (the half life) in seconds, minutes, hours, days, weeks, months, or years. In other cases the decay process takes centuries or hundreds of thousands of years before the wastes are safe for human contact. The problem as now conceptualized for HLNW managers is simple to state if not easy to achieve. The HLNW needs to be secured in some fashion until it decays, by virtue of its physical nature, to safe levels. Another possible future solution, not currently available, might be to change the ~~ructure of HLNW through high-technology processing and thus decompose the waste into units with different and less lengthy radioactivity. Learning whether this processing is a future option will require patience and generous amounts of time for research.

Focused attention by world leaders is needed to address the substantial challenges posed by disposal of spent nuclear fuel from reactors and high-level radioactive waste from processing such fuel. The biggest challenges in achieving safe and secure storage and permanent waste disposal are societal, although technical challenges remain. Disposition of radioactive wastes in a deep geological repository is a sound approach as long as it progresses through a stepwise decision-making process that takes advantage of technical advances, public participation, and international cooperation. Written for concerned citizens as well as policymakers, this book was sponsored by the U.S. Department of Energy, U.S. Nuclear Regulatory Commission, and waste management organizations in eight other countries.

This report looks at the Nuclear Waste Policy Act of 1982 (NWPA), Yucca Mountain, and the Obama Administration's de-funding of Yucca Mountain. 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. Most of the current debate surrounding civilian radioactive waste focuses on highly radioactive spent fuel from nuclear power plants.

When Congress passed the Nuclear Waste Policy Act of 1982, it directed the Department of Energy to locate, study, license, and develop a deep underground repository for high-level nuclear wastes. As the authors of this study show, by 1987 the program was in shambles, beset by opposition from every state that had a potential storage site. Congress passed amendments to the original legislation that designated Yucca Mountain, Nevada, as the only site for study and development.The authors trace the evolution of the political and social turmoil created by this difficult site-selection process, looking at the history of the nation's repository program, the nature of the public's concerns, and the effects of intergovernmental conflict. They also examine how other countries have addressed similar problems. Turning to a promising development—a dry-cask storage method judged by the Nuclear Regulatory Commission to be safe for a century or more—they urge a full reassessment of the nation's high-level nuclear waste policies and of existing DOE programs.The book concludes with carefully considered recommendations for a new national policy for the storage of hazardous nuclear waste. Everyone concerned about nuclear waste and how it should be managed at the federal, state, and local levels will find valuable information in this in-depth study of the issues at hand.

The disposal of nuclear waste is becoming a major concern. Many nuclear power plants around the world are nearing the end of their operating lives. This is particularly true in the United States where most nuclear power plants are approaching the end of the operational time period allowed in their licenses. The disposal of radioactive waste from nuclear power plants and nuclear missiles is as politically intense an issue as the plants and missiles themselves. Yet the three issues have remained curiously separate in spite of their close physical ties. Few debates on nuclear power or nuclear weapons discuss the problems of waste disposal should the power plant or missile be decommissioned. Few debates on nuclear waste disposal discuss the opportunities to close nuclear power plants or get rid of nuclear weapons a disposal site would afford. Nuclear waste can be generally classified a either "low level" radioactive waste or "high level" radioactive waste. Low level nuclear waste usually includes material used to handle the highly radioactive parts of nuclear reactors (i.e. cooling water pipes and radiation suits) and waste from medical procedures involving radioactive treatments or x-rays. Low level waste is comparatively easy to dispose of. The level of radioactivity and the half life of the radioactive isotopes in low level waste is relatively small. Storing the waste for a period of 10 to 50 years will allow most of the radioactive isotopes in low level waste to decay, at which point the waste can be disposed of as normal refuse. High level radioactive waste is generally material from the core of the nuclear reactor or nuclear weapon. This waste includes uranium, plutonium, and other highly radioactive elements made during fission. Most of the radioactive isotopes in high level waste emit large amounts of radiation and have extremely long half-lives (some longer than 100,000 years) creating long time periods before the waste will settle to safe levels of radioactivity. This new book explores the issues pertaining, either directly or indirectly, to nuclear waste disposal.
