Disposition of High-Level Waste and Spent Nuclear Fuel


Book Description

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.




Disposition of High-Level Radioactive Waste Through Geological Isolation


Book Description

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.




The Dilemma of Siting a High-Level Nuclear Waste Repository


Book Description

This book explores siting dilemmas - situations in which an "authority" (e.g., Congress, a consortium of utilities) deems it in the best interest of society to build a facility such as an incinerator, but opponents living near the proposed site thwart the plan. Facility developers typically attribute local opposition to selfishness or radically inaccurate views of the risks posed by the facility. We examine the validity of these conclusions by looking in depth at the psychological response that arises when residents are faced with the prospect of living near waste disposal facilities. The particular siting dilemma considered in this book is the problem of how to "dispose" of the high-level nuclear wastes accumulating at nuclear power plants in the United States. These wastes, in the form of "spent" fuel rods, will emit dangerous levels of radioactivity for thousands of years - anywhere between 10,000 and 100,000 years, depending on the margin of safety one adopts. The current proposal is to encase the spent fuel in corrosion-resistant canisters and then to bury these canisters deep underground in a geologic repository. The two of us became involved with the high-level waste issue in 1986 as part of an interdisciplinary research team hired by the State of Nevada. The charge of this team was to estimate the socioeconomic impacts that would accompany a repository if it were built at Yucca Mountain, approximately 100 miles northwest of Las Vegas.




Uncertainty Underground

Cement-Based Materials for Nuclear Waste Storage


Book Description

As the re-emergence of nuclear power as an acceptable energy source on an international basis continues, the need for safe and reliable ways to dispose of radioactive waste becomes ever more critical. The ultimate goal for designing a predisposal waste-management system depends on producing waste containers suitable for storage, transportation and permanent disposal. Cement-Based Materials for Nuclear-Waste Storage provides a roadmap for the use of cementation as an applied technique for the treatment of low- and intermediate-level radioactive wastes. Coverage includes, but is not limited to, a comparison of cementation with other solidification techniques, advantages of calcium-silicate cements over other materials and a discussion of the long-term suitability and safety of waste packages as well as cement barriers.




Conflicts, Participation and Acceptability in Nuclear Waste Governance


Book Description

This book is the last part of a trilogy and concludes a long-term project that focussed on nuclear waste governance in 24 countries. It deals with core themes of the disposal of high-level radioactive waste (HLW), e.g. the wicked problems of housing nuclear waste disposal facilities, public participation and public discourse, voluntarism and compensation in siting as well as the role of advisory bodies and commissions. The volume reflects on the diverse factors that shape the debate on what can be considered an ”acceptable solution” and on various strategies adopted in order to minimise conflicts and possibly increase acceptability. The various theoretical and empirical contributions shed light on several mechanisms and issues touched upon in these strategies, such as the role of trust, voluntarism, economic interests at stake, compensation, ethics, governance, and participation.




Deep Time Reckoning


Book Description

A guide to long-term thinking: how to envision the far future of Earth. We live on a planet careening toward environmental collapse that will be largely brought about by our own actions. And yet we struggle to grasp the scale of the crisis, barely able to imagine the effects of climate change just ten years from now, let alone the multi-millennial timescales of Earth's past and future life span. In this book, Vincent Ialenti offers a guide for envisioning the planet's far future—to become, as he terms it, more skilled deep time reckoners. The challenge, he says, is to learn to inhabit a longer now. Ialenti takes on two overlapping crises: the Anthropocene, our current moment of human-caused environmental transformation; and the deflation of expertise—today's popular mockery and institutional erosion of expert authority. The second crisis, he argues, is worsening the effects of the first. Hearing out scientific experts who study a wider time span than a Facebook timeline is key to tackling our planet's emergency. Astrophysicists, geologists, historians, evolutionary biologists, climatologists, archaeologists, and others can teach us the art of long-termism. For a case study in long-term thinking, Ialenti turns to Finland's nuclear waste repository “Safety Case” experts. These scientists forecast far future glaciations, climate changes, earthquakes, and more, over the coming tens of thousands—or even hundreds of thousands or millions—of years. They are not pop culture “futurists” but data-driven, disciplined technical experts, using the power of patterns to construct detailed scenarios and quantitative models of the far future. This is the kind of time literacy we need if we are to survive the Anthropocene.
