Nuclear power has demonstrated over the last 30 years its capacity to produce base-load electricity at a low, predictable and stable cost due to the very low economic dependence on the price of uranium. However the management of used nuclear fuel remains the "Achilles' Heel" of this energy source since the storage of used nuclear fuel is increasing as evidenced by the following number with 2,000 tons of UNF produced each year by the 104 US nuclear reactor units which equates to a total of 62,000 spent fuel assemblies stored in dry cask and 88,000 stored in pools. Two options adopted by several countries will be presented. The first one adopted by Europe, Japan and Russia consists of recycling the used nuclear fuel after irradiation in a nuclear reactor. Ninety six percent of uranium and plutonium contained in the spent fuel could be reused to produce electricity and are worth recycling. The separation of uranium and plutonium from the wastes is realized through the industrial PUREX process so that they can be recycled for re-use in a nuclear reactor as a mixed oxide (MOX) fuel. The second option undertaken by Finland, Sweden and the United States implies the direct disposal of used nuclear fuel into a geologic formation. One has to remind that only 30% of the worldwide used nuclear fuel are currently recycled, the larger part being stored (70% in pool) waiting for scientific or political decisions. A third option is emerging with a closed fuel cycle which will improve the global sustainability of nuclear energy. This option will not only decrease the volume amount of nuclear waste but also the long-term radiotoxicity of the final waste, as well as improving the long-term safety and the heat-loading of the final repository. At the present time, numerous countries are focusing on the R & D recycling activities of the ultimate waste composed of fission products and minor actinides (americium and curium). Several new chemical extraction processes, such as TRUSPEAK, ALSEP, EXAM, or LUCA are pursued worldwide and their approaches will be highlighted.

There have been reports on limitations in the mgmt. of U.S. low-level radioactive waste (LLRW). To identify potential approaches to overcome these limitations, the author examined the extent to which other countries have: LLRW inventory databases; timely removal of higher-activity LLRW from waste generator sites; disposition options for all LLRW; & requirements that LLRW generators have financial reserves to cover waste disposition costs, as well as any other approaches that might improve U.S. LLRW mgmt. The author surveyed 18 countries representing leading LLRW generators to identify their mgmt. approaches & to compare them with U.S. survey results & with approaches by LLRW generators, disposal operators, & regulators in the U.S. Ill.

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.

The Department of Energy's Office of Environmental Management (DOE) is responsible for the safe cleanup of sites used for nuclear weapons development and government-sponsored nuclear energy research. Low-level radioactive waste (LLW) is the most volumetrically significant waste stream generated by the DOE cleanup program. LLW is also generated through commercial activities such as nuclear power plant operations and medical treatments. The laws and regulations related to the disposal of LLW in the United States have evolved over time and across agencies and states, resulting in a complex regulatory structure. DOE asked the National Academies of Sciences, Engineering, and Medicine to organize a workshop to discuss approaches for the management and disposition of LLW. Participants explored the key physical, chemical, and radiological characteristics of low-level waste that govern its safe and secure management and disposal in aggregate and in individual waste streams, and how key characteristics of low level waste are incorporated into standards, orders, and regulations that govern the management and disposal of LLW in the United States and in other major waste-producing countries. This publication summarizes the presentations and discussions from the workshop.

The safe management of radioactive wastes is of paramount importance in gaining both governmental and societal support for nuclear energy. The scope of this new textbook is to provide a comprehensive perspective on all types of radioactive wastes as to how they are created, classified, characterized, and disposed.Written to emphasize how geology and radionuclide chemistry impact waste management, this book is primarily designed for engineers who have little background in geology with low-level wastes, decommissioning wastes, high-level wastes and spent nuclear fuel.This textbook provides the most up-to-date information available on waste management in several countries. The content of this work includes transporting radioactive materials to disposal facilities. The textbook cites numerous case studies to illustrate past practices, current methodologies and to provide insights on how radioactive wastes may be managed in the future. An international perspective on waste management is also provided to help the readers better understand the diversity in approaches while highlighting what many countries have in common. Review questions for classroom use are provided at the end of each chapter.Related Link(s)

National radioactive waste management programmes are in various phases of siting facilities and rely on distinct technical approaches for different categories of waste. In all cases, it is necessary for institutional actors And The potential or actual host community to build a meaningful, workable relationship. Partnership approaches are effective in achieving a balance between the requirements of fair representation and competent participation. With host community support, they also help ensure the desirable combination of a licensable site and management concept as well as a balance between compensation, local control and development opportunities. This report provides up-to-date information on experience with local partnership arrangements in 13 countries. The characteristics, advantages and aims of community partnerships are also described in addition To The concept's evolution over the past decade.

Over the past decade significant progress has been achieved in the development of waste characterization and control procedures and equipment as a direct response to ever-increasing requirements for quality and reliability of information on waste characteristics. Failure in control procedures at any step can have important, adverse consequences and may result in producing waste packages which are not compliant with the waste acceptance criteria for disposal, thereby adversely impacting the repository. The information and guidance included in this publication corresponds to recent achievements and reflects the optimum approaches, thereby reducing the potential for error and enhancing the quality of the end product. -- Publisher's description.

This new volume offers effective solutions to the mismanagement of waste, particularly in developing countries, by providing an understanding of different types of wastes, their generation, and use of advanced technologies for waste management, and by focusing on integrating the technical and regulatory complexities of waste management. It provides a comprehensive overview of the characterization, issues, and regulatory development of waste management for sustainable solutions and prevention techniques. Covering the various types of pollution, including pollution from plastics, industrial activities, metals, livestock, healthcare, food loss and waste, etc., the book explores new techniques for thermal and radioactive waste management and includes such methods as vermicomposting and composting for organic waste management and profitable use. The volume also looks at the role of modern technologies and legislation measures to manage biosolid waste. Numerous data sets obtained from various surveys are included, and special categories of waste that may not fit precisely into either RCRA Subtitle D (solid wastes) or Subtitle C (hazardous wastes) are discussed as well.
