Technology, Uses, Irradiated Fuel, Reprocessing by J.R. Allen,R. Benz,R. Förthmann,A. Naoumidis,D.R. Pemberton,H. Vietzke Pdf

In connection with the recent treatment of radium and the actinides, the Gmelin Institute is carrying out the description of thorium and its compounds. The supplement volume A 2 comprising the history, isotopes and the recovery of thorium and the supplement volumes C 1, C 2 and C 3 describing the compounds with the noble gases, hydrogen, oxygen compounds and nitrogen compounds have already been published; also published is supplement volume C 5 describing the compounds with sulfur, selenium, tellurium, and boron. The supplement volume D 1 and D 2 describing the properties of thorium ions in solution and the solvent extraction of thorium, as well as supplement volume E describing the coordination compounds have also been published. The present volume deals with the technical fabrication of important thorium compounds and their uses in the nuclear and non-nuclear fields. It also describes in detail the behavior of thorium nuclear fuels during operation of a nuclear power plant as well as the reprocessing of burnt-up thorium fuels. By far the most important Th compound is ThO2 due to its high chemical and thermal stability as well as its high melting point near 3000°C, the highest for any metal oxide. The inherent radioactivity of 232Th and the formation of radioactive daughter products are important limiting factors in the technical scale use of thorium compounds because of necessary radiation protection measures and of health physics. 232Th is transformed by neutrons to the fissile uranium isotope 233U. Thorium therefore is an excellent breeding material, especially for high-temperature reactors. A lot of basic and technical investigations for reprocessing of spent thorium fuel have to be done; no such reprocessing plants exist as yet.

Advanced Separation Techniques for Nuclear Fuel Reprocessing and Radioactive Waste Treatment by Kenneth L Nash,Gregg J Lumetta Pdf

Advanced separations technology is key to closing the nuclear fuel cycle and relieving future generations from the burden of radioactive waste produced by the nuclear power industry. Nuclear fuel reprocessing techniques not only allow for recycling of useful fuel components for further power generation, but by also separating out the actinides, lanthanides and other fission products produced by the nuclear reaction, the residual radioactive waste can be minimised. Indeed, the future of the industry relies on the advancement of separation and transmutation technology to ensure environmental protection, criticality-safety and non-proliferation (i.e., security) of radioactive materials by reducing their long-term radiological hazard. Advanced separation techniques for nuclear fuel reprocessing and radioactive waste treatment provides a comprehensive and timely reference on nuclear fuel reprocessing and radioactive waste treatment. Part one covers the fundamental chemistry, engineering and safety of radioactive materials separations processes in the nuclear fuel cycle, including coverage of advanced aqueous separations engineering, as well as on-line monitoring for process control and safeguards technology. Part two critically reviews the development and application of separation and extraction processes for nuclear fuel reprocessing and radioactive waste treatment. The section includes discussions of advanced PUREX processes, the UREX+ concept, fission product separations, and combined systems for simultaneous radionuclide extraction. Part three details emerging and innovative treatment techniques, initially reviewing pyrochemical processes and engineering, highly selective compounds for solvent extraction, and developments in partitioning and transmutation processes that aim to close the nuclear fuel cycle. The book concludes with other advanced techniques such as solid phase extraction, supercritical fluid and ionic liquid extraction, and biological treatment processes. With its distinguished international team of contributors, Advanced separation techniques for nuclear fuel reprocessing and radioactive waste treatment is a standard reference for all nuclear waste management and nuclear safety professionals, radiochemists, academics and researchers in this field. A comprehensive and timely reference on nuclear fuel reprocessing and radioactive waste treatment Details emerging and innovative treatment techniques, reviewing pyrochemical processes and engineering, as well as highly selective compounds for solvent extraction Discusses the development and application of separation and extraction processes for nuclear fuel reprocessing and radioactive waste treatment

Nuclear Wastes by National Research Council,Division on Earth and Life Studies,Commission on Geosciences, Environment and Resources,Committee on Separations Technology and Transmutation Systems Pdf

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.
