tailieunhanh - Radionuclide behaviour in the natural environment

During my career, some 35 years, there has been a growing realization that the goal of successful nuclear waste management and the final disposal of long-lived radionuclides can only be attained by a thorough understanding of the behavior of key, technogenic radionuclides in the environment. Within a nuclear reactor, these radionuclides are created by fission, neutron capture and subsequent beta-decay reactions on actinides, mainly 238 U, and by activation nuclear reactions. These reactor-created nuclides in used fuel or reprocessed waste are the ‘stuff’ that is destined for deep geologic disposal. Lesser amounts of radioactivity may be released as nuclear materials are. | Woodhead publishing series in energy Radionuclide behaviour in the natural environment Science implications and lessons for the nuclear industry Edited by Christophe Poinssot and Horst Geckeis WOODHEAD PUBLISHING Radionuclide behaviour in the natural environment Woodhead Publishing Limited 2012 Related titles Geological repository systems for safe disposal of spent nuclear fuels and radioactive waste ISBN 978-1-84569-542-2 The long-term safety of spent nuclear fuel and radioactive waste materials must be assured without active human oversight based on the requirement that we do not pass the burden of nuclear waste onto future generations. Geological disposal systems and technology utilising both natural geological barriers and engineered barrier systems have been developed to isolate nuclear wastes from the human environment. This book critically reviews state-of-the-art technologies scientific methods and engineering practices directly related to the design operation and safety of geological repositories. Infrastructure and methodologies for the justification of nuclear power programmes ISBN 978-1-84569-973-4 The potential development of any nuclear power programme requires a rigorous justification process built upon an objective infrastructure reviewing the substantial regulatory economic and technical information required to appropriately decide upon implementation of such a long-term commitment. Both new entrants and those countries wishing to renovate their nuclear fleets after a moratorium will need to develop and apply appropriate infrastructures to review the justification of the potential use of nuclear power. This book provides a comprehensive review of the infrastructure and methodologies required to justify the implementation of nuclear power programmes in any country choosing to review this path.
