Book Description
The immobilization of high level liquid wastes from the repro-cessing of irradiated nuclear fuels is of great interest, and serious efforts are being undertaken to find a satisfactory technical solution. Volatilization of fission product elements during immobilization poses the potential for the release of radioactive substances to the environment and necessitates effective off-gas cleaning systems. This report describes typical off-gas cleaning systems used in the most advanced high level liquid waste immobilization plants and considers most of the aerosols and volatile contaminants.

Book Description
A major issue in the cleanup of this country's nuclear weapons complex is how to dispose of the radioactive waste resulting primarily from the chemical processing operations for the recovery of plutonium and other defense strategic nuclear materials. The wastes are stored in hundreds of large underground tanks at four U.S. Department of Energy (DOE) sites throughout the United States. The tanks contain hundreds of thousands of cubic meters of radioactive and hazardous waste. Most of it is high-level waste (HLW), some of it is transuranic (TRU) or low- level waste (LLW), and essentially all containing significant amounts of chemicals deemed hazardous. Of the 278 tanks involved, about 70 are known or assumed to have leaked some of their contents to the environment. The remediation of the tanks and their contents requires the development of new technologies to enable cleanup and minimize costs while meeting various health, safety, and environmental objectives. While DOE has a process based on stakeholder participation for screening and formulating technology needs, it lacks transparency (in terms of being apparent to all concerned decision makers and other interested parties) and a systematic basis (in terms of identifying end states for the contaminants and developing pathways to these states from the present conditions). An End State Methodology for Identifying Technology Needs for Environmental Management, with an Example from the Hanford Site Tanks describes an approach for identifying technology development needs that is both systematic and transparent to enhance the cleanup and remediation of the tank contents and their sites. The authoring committee believes that the recommended end state based approach can be applied to DOE waste management in general, not just to waste in tanks. The approach is illustrated through an example based on the tanks at the DOE Hanford Site in southeastern Washington state, the location of some 60 percent by volume of the tank waste residues.

Book Description
Separation Techniques in Nuclear Waste Management is an up-to-date, comprehensive survey of processes for separation of nuclear wastes. Comprised of articles by scientists and engineers at universities and national laboratories in the U.S. and overseas, the book provides excellent reference information for individuals working in nuclear waste management. Specifically, the book covers current separation technologies and techniques for waste liquid, solid, and gas streams that contain radionuclides. Such wastes are typical of those produced as a result of nuclear materials processing and spent fuel reprocessing. Chapters on promising new technologies and state-of-the-art processes currently in use provide valuable information for design engineers, as well as for research scientists. The articles in Separation Techniques in Nuclear Waste Management are brief and concise - designed for quick access to pertinent information. Many of the contributors are leaders in their fields. It is the most current survey available of the latest nuclear waste management techniques.

Book Description
Radioactive waste management and contaminated site clean-up reviews radioactive waste management processes, technologies, and international experiences. Part one explores the fundamentals of radioactive waste including sources, characterisation, and processing strategies. International safety standards, risk assessment of radioactive wastes and remediation of contaminated sites and irradiated nuclear fuel management are also reviewed. Part two highlights the current international situation across Africa, Asia, Europe, and North America. The experience in Japan, with a specific chapter on Fukushima, is also covered. Finally, part three explores the clean-up of sites contaminated by weapons programmes including the USA and former USSR.Radioactive waste management and contaminated site clean-up is a comprehensive resource for professionals, researchers, scientists and academics in radioactive waste management, governmental and other regulatory bodies and the nuclear power industry. - Explores the fundamentals of radioactive waste including sources, characterisation, and processing strategies - Reviews international safety standards, risk assessment of radioactive wastes and remediation of contaminated sites and irradiated nuclear fuel management - Highlights the current international situation across Africa, Asia, Europe, and North America specifically including a chapter on the experience in Fukushima, Japan

Book Description
Based on the authors' recent investigations, this book describes the application of glassy and polyphase composite materials for nuclear waste immobilisation. It introduces immobilisation issues beginning with a short description of nuclear waste types and compositions. Sources of nuclear waste are described including the nuclear fuel cycle, operational and spent nuclear fuel reprocessing waste streams. The glassy waste forms currently being used for high-, intermediate- and low level radioactive waste immobilisation are described. Problems related to immobilisation capacity, process efficiency and long-term radionucleide retention are highlighted. Scientific and technical problems in nuclear waste immobilisation are emphasised in particular long-term waste form stability and durability. Recent developments in advanced nuclear waste forms are described such as glass composite materials (GCM) with higher versatility and waste loading. New immobilisation approaches and technologies are described including advanced cold crucible induction melting (CCM), self sustaining thermochemical immobilisation (SSI), and in-situ self-sintering in deep underground repositories. Long-term durability tests of nuclear waste glasses are outlined and the role of ion-exchange phase in glass corrosion is described in detail.

Book Description
With detailed photos and schematic system diagrams, the Hazardous and Radioactive Waste Treatment Technologies Handbook provides the latest information on current technologies in the market. Intended as a reference for scientists, engineers, and engineering students, it covers waste-related thermal and non-thermal technologies, separation techniques, and stabilization technologies. It provides an overview of recent waste technologies, for both hazardous chemical wastes and radioactive wastes. By implementing the techniques presented in this book, readers will be able to decide which appropriate technology to use and how to design the equipment for their particular needs.
