Download or read book Leaching of Low and Medium Level Waste Packages Under Disposal Conditions written by M. Dozol and published by Springer. This book was released on 1986-08-31 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leaching tests are conducted according to different standards, pro cedures or recommendations, generally under conditions different from those of the disposal media. Such tests are generally useful for com paring various containment matrices to ensure maximum isolation of radionuclides, and allow waste conditioning processes to be optimized. However, when defining release hypotheses to be taken into consideration for risk analysis, these methods can often lead to hypothesis which are either too optimistic or too pessimistic. The uncertainties basically involve the processes by which containers deteriorate during transport, handling and utlimate storage. Moreover, the interpretation of test results must be more clearly correlated with the known physico-chemical mechanisms involved. In attempting to find an answer to this question, tests have already the recovery been undertaken, including the use of lysimeter devices or of waste materials after several years of storage. The aim of the seminar was to exchange views among experts in characterization, waste management and safety analysis for the purpose of defining the principal actions that could be undertaken or of reorienting ongoing studies in order to limit the uncertainties involved.

Download or read book Leaching Low Level Radioactive Waste in Simulated Disposal Conditions written by LP. Buckley and published by . This book was released on 1989 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leaching tests formally recognized by the International Atomic Energy Agency (IAEA) or by the American Nuclear Society (ANS) are used to evaluate the release of radioactivity from a waste form under idealized conditions. These conditions do not represent the reality of disposal environments, where engineered barriers are in place to limit access of water and to retard the migration of radionuclides into the biosphere. A test program underway at Chalk River, Ontario is attempting to provide an understanding of the release and transport of radionuclides under more realistic conditions. Preliminary results indicate that releases are suppressed by at least an order of magnitude when the effects of barriers in a repository failure are considered. However, migration mechanisms cannot be fully explained by classical concepts involving saturated flow. Research effort is now focused on measurements in an unsaturated, reducing environment, the condition which will be expected to be found in a well-designed repository.
Download or read book Strategy and Methodology for Radioactive Waste Characterization written by International Atomic Energy Agency and published by IAEA. This book was released on 2007 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book An Introduction to Nuclear Waste Immobilisation written by Michael I. Ojovan and published by Elsevier. This book was released on 2010-07-07 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety and environmental impact is of uppermost concern when dealing with the movement and storage of nuclear waste. The 20 chapters in 'An Introduction to Nuclear Waste Immobilisation' cover all important aspects of immobilisation, from nuclear decay, to regulations, to new technologies and methods. Significant focus is given to the analysis of the various matrices used in transport: cement, bitumen and glass, with the greatest attention being given to glass. The last chapter concentrates on the performance assessment of each matrix, and on new developments of ceramics and glass composite materials, thermochemical methods and in-situ metal matrix immobilisation. The book thoroughly covers all issues surrounding nuclear waste: from where to locate nuclear waste in the environment, through nuclear waste generation and sources, treatment schemes and technologies, immobilisation technologies and waste forms, disposal and long term behaviour. Particular attention is paid to internationally approved and worldwide-applied approaches and technologies. * Each chapter focuses on a different matrix used in nuclear waste immobilisation: Cement, bitumen, glass and new materials. * Keeps the most important issues surrounding nuclear waste – such as treatment schemes and technologies, and disposal - at the forefront.
Download or read book Disposition of High Level Waste and Spent Nuclear Fuel written by National Research Council and published by National Academies Press. This book was released on 2001-07-05 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
