Christensen and published by Pinewa, Man. : Whiteshell Laboratories. This book was released on 1994 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiolysis of groundwater would produce oxidants and reductants that could affect the oxidation and dissolution of used fuel (UO2) placed in a geological disposal vault. To avoid the extensive experimentation involved, a kinetic model originally proposed by Christensen and Bjergbakke to predict the rate of UO2 dissolution induced by water radiolysis is being refined. This report summarizes the understanding of the mechanisms of oxidation and dissolution of UO2 as well as other pertinent experimental results used in then of UO2 as well as other pertinent experimental results used in the refinement of the original model. The model and its refinements are described and the rates predicted are presented. These predicted dissolution rates are then compared with the rates determined from the electro-chemical model. The limitations and necessary further developments are then discussed.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The reprocessing of spent nuclear fuel is a very important step in the nuclear fuel cycle and one of the greatest ways to ensure the sustainability of the civil nuclear industry. In France, the PUREX process is used to separate the reusable Uranium and Plutonium from the fission products and minor actinides that will then be disposed as waste. The dissolution of the spent fuel is at the head-end of this process and thus has a big impact on the following stages. The present work was done in the context of the development of a model for the dissolution step that will be used to design the dissolution reactors of the future. Some of the inputs this model will need are the kinetic constants of the dissolution reactions, which are quite complex. To achieve this, the dissolution of small grains of UO2 was studied under several experimental conditions. An algorithm was developed with the software MatLab which takes as input the images of the grains taken at regular intervals during the dissolution and as an output the dissolution rates in nm/s and mol/m2 /s. The algorithm binarises the grain images in order to have a clear distinction between grain and background, follows the area and perimeter of the oxide grains throughout the dissolution and finally calculates the wished results. The dissolution speeds at different experimental conditions will allow for the calculations of kinetic constants and activation energies which will then feed the dissolution model.

Available in PDF, EPUB and Kindle. Book excerpt: The term transport phenomena is used to describe processes in which mass, momentum, energy and entropy move about in matter. Advances in Transport Phenomena provide state-of-the-art expositions of major advances by theoretical, numerical and experimental studies from a molecular, microscopic, mesoscopic, macroscopic or megascopic point of view across the spectrum of transport p- nomena, from scientific enquiries to practical applications. The annual review series intends to fill the information gap between regularly published journals and university-level textbooks by providing in-depth review articles over a broader scope than in journals. The authoritative articles, contributed by international- leading scientists and practitioners, establish the state of the art, disseminate the latest research discoveries, serve as a central source of reference for fundamentals and applications of transport phenomena, and provide potential textbooks to senior undergraduate and graduate students. The series covers mass transfer, fluid mechanics, heat transfer and thermo- namics. The 2009 volume contains the four articles on biomedical, environmental and nanoscale transports. The editorial board expresses its appreciation to the c- tributing authors and reviewers who have maintained the standard associated with Advances in Transport Phenomena. We also would like to acknowledge the efforts of the staff at Springer who have made the professional and attractive pr- entation of the volume. Serial Editorial Board Editor-in-Chief Professor L. Q.

Available in PDF, EPUB and Kindle. Book excerpt: The implementation of advanced nuclear systems requires that new technologies associated with the back end of the fuel cycle are developed. The separation of minor actinides from other fuel components is one of the advanced concepts being studied to help close the nuclear fuel cycle and to improve the long-term effects on the performance of geological repositories. Separating spent fuel elements and subsequently converting them through transmutation into short-lived nuclides should considerably reduce the longterm risks associated with nuclear power generation.

Download or read book Geological Repository Systems for Safe Disposal of Spent Nuclear Fuels and Radioactive Waste written by Michael J Apted and published by Elsevier. This book was released on 2010-07-27 with total page 789 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological disposal has been internationally adopted as the most effective approach to assure the long-term, safe disposition of the used nuclear fuels and radioactive waste materials produced from nuclear power generation, nuclear weapons programs, medical, treatments, and industrial applications. Geological repository systems take advantage of natural geological barriers augmented with engineered barrier systems to isolate these radioactive materials from the environment and from future populations. Geological repository systems for safe disposal of spent nuclear fuels and radioactive waste critically reviews the state-of-the-art technologies, scientific methods, regulatory developments, and social engagement approaches directly related to the implementation of geological repository systems. Part one introduces geological disposal, including multiple-barrier geological repositories, as well as reviewing the impact of nuclear fuel recycling practices and underground research laboratory activities on the development of disposal concepts. Part two reviews geological repository siting in different host rocks, including long-term stability analysis and radionuclide transport modelling. Reviews of the range of engineered barrier systems, including waste immobilisation technologies, container materials, low pH concretes, clay-based buffer and backfill materials, and barrier performance are presented in Part three. Part four examines total system performance assessment and safety analyses for deep geological and near-surface disposal, with coverage of uncertainty analysis, use of expert judgement for decision making, and development and use of knowledge management systems. Finally, Part five covers regulatory and social approaches for the establishment of geological disposal programs, from the development of radiation standards and risk-informed, performance-based regulations, to environmental monitoring and social engagement in the siting and operation of repositories. With its distinguished international team of contributors, Geological repository systems for safe disposal of spent nuclear fuels and radioactive waste is a standard reference for all nuclear waste management and geological repository professionals and researchers. Critically reviews the state-of-the-art technologies, scientific methods, regulatory developments, and social engagement approaches related to the implementation of geological repository systems Chapters introduce geological disposal and review the development of disposal concepts Examines long-term stability analysis, the range of engineered barrier systems and barrier performance

Available in PDF, EPUB and Kindle. Book excerpt: 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.
