This book was released on 2023-12-13 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety concepts regarding nuclear waste disposal in underground repositories generally rely on a combination of engineered and geological barriers that minimize potential radionuclide release out of the containment-providing rock zone and transport through the biosphere. The presence of water, however, may alter the engineered barrier system, dissolve radionuclides, and facilitate radionuclide transport that over time may permeate the biosphere. So while barrier systems aim to prevent or hinder water from contacting the waste, the possible intrusion of aqueous solutions must be considered for several safety case scenarios impacted by the long-term evolution of a repository. Dissolution and solubility phenomena thus arise as important processes controlling the chemical behaviour of radionuclides and other key materials of relevance in the context of such repositories and their safety assessments. The solubility and aqueous speciation of radionuclides is of particular interest as they provide upper limits of water-transportable concentrations of radionuclides. Solubility phenomena of radioactive and other gases in water provide important information on gas transport and pressure build-up. Moreover, solubility assessments offer insight into time-independent constraints on the evolution of the disposal system. Particularly important in this regard is the geochemical modelling of radionuclide behaviour in the engineered barrier system as well as in natural aquatic systems along the transport path of radionuclides to the biosphere. The obtained information provides valuable inputs that appropriately constrain safety analyses of nuclear waste disposal.

This book was released on 2012-04-05 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: In today's world of increasingly stringent environmental regulations, it is critical to identify and adequately address environmental issues in the ceramic industry to ensure success. In addition, ceramics and glasses play a critical role in the nuclear industry. Nuclear fuels and waste forms for low-level and high-level radioactive, mixed, and hazardous wastes are primarily either ceramic of glass. Effective and responsible environmental stewardship is becoming increasingly more important in the world. These proceedings detail the results of the ongoing effort in these areas.

This book was released on 2012-03-28 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composed from two symposia conducted at the 2001 Annual Meeting of The American Ceramic Society, this new volume details the advances in the state of knowledge in nuclear and waste materials science and technology. Highlighted are areas of rapid change such as in the application, development, and testing of ceramics and glasses in the nuclear and waste industries. As companies begin to focus on ¿green ceramics¿ and the manufacturing of environmentally friendly products, the development of innovative processing approaches and novel environmental treatment technologies soon follows. These are being developed to address more stringent regulations and to obtain an improved scientific understanding of the industrial processes and treatment technologies. This seventh volume in the series addresses current nuclear and environmental problems and provides solutions for them. It is an excellent resource for researchers and scientists involved in the ceramic and nuclear industries. roceedings of the symposium held at the 103rd Annual Meeting of The American Ceramic Society, April 22-25, 2001, in Indiana; Ceramic Transactions, Volume 132.

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.

This book was released on 2011-09-05 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy's Office of Environmental Management (DOE-EM) is responsible for cleaning up radioactive waste and environmental contamination resulting from five decades of nuclear weapons production and testing. A major focus of this program involves the retrieval, processing, and immobilization of waste into stable, solid waste forms for disposal. Waste Forms Technology and Performance, a report requested by DOE-EM, examines requirements for waste form technology and performance in the cleanup program. The report provides information to DOE-EM to support improvements in methods for processing waste and selecting and fabricating waste forms. Waste Forms Technology and Performance places particular emphasis on processing technologies for high-level radioactive waste, DOE's most expensive and arguably most difficult cleanup challenge. The report's key messages are presented in ten findings and one recommendation.

Available in PDF, EPUB and Kindle. Book excerpt: The recovery of solid wastes for the preparation of innovative composite materials not only represents an economic advantage, but also offers an ecological opportunity for the utilization of by-products which would otherwise be landfilled. Specifically, the reuse and recycling of waste lead to important savings of raw materials and energy, since these by-products, generally deriv from agricultural or industrial activities, are abundant in nature. Moreover, a reduction of the environmental and related sanitary impacts can be also achieved. For this reason, a recycling operation is fundamental for the improvement of the environmental sustainability, because these secondary raw materials become a resource that can be easily reused without the modification of the peculiar characteristics, in order to obtain new and performing composites, with a low specific weight, high durability, and long life cycle.
