Disposal of radioactive waste from nuclear weapons production and power generation has caused public outcry and political consternation. Nuclear Wastes presents a critical review of some waste management and disposal alternatives to the current national policy of direct disposal of light water reactor spent fuel. The book offers clearcut conclusions for what the nation should do today and what solutions should be explored for tomorrow. The committee examines the currently used "once-through" fuel cycle versus different alternatives of separations and transmutation technology systems, by which hazardous radionuclides are converted to nuclides that are either stable or radioactive with short half-lives. The volume provides detailed findings and conclusions about the status and feasibility of plutonium extraction and more advanced separations technologies, as well as three principal transmutation concepts for commercial reactor spent fuel. The book discusses nuclear proliferation; the U.S. nuclear regulatory structure; issues of health, safety and transportation; the proposed sale of electrical energy as a means of paying for the transmutation system; and other key issues....

ISBN : 9780309170888

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....

Recognizing the critical need to address the issue of nuclear waste disposal, the Congress enacted the Nuclear Waste Policy Act of 1982 to establish a comprehensive policy and program for the safe, permanent disposal of commercial spent fuel and other highly radioactive wastes in one or more mined geologic repositories. In the act, the Congress stated that federal efforts to devise a permanent solution for disposing of radioactive waste had been inadequate. The act charged DOE with (1) establishing criteria for the recommendation of sites for repositories; (2) "characterizing" (investigating) three sites to determine each site's suitability for a repository; (3) recommending one suitable site to the President who, if he considers the site is qualified for a license application, submits a recommendation of such site to the Congress; and (4) upon approval of a recommended site, seeking a license from NRC to construct and operate a repository at the approved site. The act created the Office of Civilian Radioactive Waste Management within DOE to manage its nuclear waste program. When the act was passed, it was expected that a repository could be operational in 1998. Amendments to the act in 1987 directed DOE to investigate only the Yucca Mountain site. These amendments also established the Nuclear Waste Technical Review Board (the Board). The Board's decision is to review the technical and scientific validity of DOE's activities associated with investigating the site and packaging and transporting wastes, and to report its findings and recommendations to the Congress and DOE at least twice each year. The act does not require DOE to implement the Board's recommendations....

Improving The Regulation And Management Of Low Activity Radioactive Wastes

The largest volumes of radioactive wastes in the United States contain only small amounts of radioactive material. These low-activity wastes (LAW) come from hospitals, utilities, research institutions, and defense installations where nuclear material is used. Millions of cubic feet of LAW also arise every year from non-nuclear enterprises such as mining and water treatment. While LAW present much less of a radiation hazard than spent nuclear fuel or high-level radioactive wastes, they can cause health risks if controlled improperly. Improving the Regulation and Management of Low-Activity Radioactive Wastes asserts that LAW should be regulated and managed according to the degree of risk they pose for treatment, storage, and disposal. Current regulations are based primarily on the type of industry that produced the waste-the waste's origin-rather than its risk. In this report, a risk-informed approach for regulating and managing all types of LAW in the United States is proposed. Implemented in a gradual or stepwise fashion, this approach combines scientific risk assessment with public values and perceptions. It focuses on the hazardous properties of the waste in question and how they compare with other waste materials. The approach is based on established principles for risk-informed decision making, current risk-informed initiatives by waste regulators in the United States and abroad, solutions available under current regulatory authorities, and remedies through new legislation when necessary....

Nuclear Waste Disposal: Can We Rely on Bedrock? focuses on a proposed solution to disposing nuclear waste, which is to deposit canisters of nuclear waste in tunnels and rooms in deep rock formations at depths of about 500 – 1100 m (1600 – 3600 ft.). This underground facility in a large body of rock is known as a repository. This book explains that the tunnels and rooms are excavated by mining techniques and the waste canisters placed in vertical drill holes in the floor. This text also discusses the concept known as mined geological disposal of nuclear wastes. Other topics covered include the form and final disposal of nuclear wastes; nature of rock and groundwater; and disturbed rock and groundwater. This book also explains the long-term behavior of the rock and the groundwater; nuclear waste leakage into the groundwater; and possible positive and negative effects of mined geological disposal. This text is essential for students of environmental science, especially those conducting research on nuclear energy....

One of the largest, most complicated and expensive environmental problems in the United States is the cleanup of nuclear wastes. The US Department of Energy (DOE) has approximately 4,000 contaminated sites covering tens of thousands of acres and replete with contaminated hazardous or radioactive waste, soil, or structures. In addition to high-level waste, it has more than 250,000 cubic meters of transuranic waste and millions of cubic meters of low-level radio-active waste. In addition, DOE is responsible for thousands of facilities awaiting decontamination, decommissioning, and dismantling. DOE and its predecessors have been involved in the management of radioactive wastes since 1943, when such wastes were first generated in significant quantities as by-products of nuclear weapons production. Waste connected with DOE's nuclear weapons complex has been accumulating as a result of various operations spanning over five decades. The cost estimates for nuclear waste cleanup in the United States have been rapidly rising. It has recently been estimated to be in a range from $200 to $350 billion. Costs could vary considerably based on future philosophies as to whether to isolate certain sites (the ""iron fence"" philosophy), or clean them up to a pristine condition (the ""greenfields"" philosophy). Funding will also be based on Congressional action that may reduce environmental cleanup, based on budget considerations....

This report examines the environmental and human health impacts from wastes dumped into the Arctic and North Pacific regions, from nuclear contaminants discharged into these environments, and from radioactive releases from both past and future nuclear activities in the region. The report presents what is known and unknown about this waste and contamination and how it may affect public health. Because so many factors are involved and science cannot provide absolute answers to many questions, this study emphasizes the need for care, caution, awareness, and prudence. It also stresses the need for a stable and enduring institutional framework and international cooperation for long term observation and monitoring....
