Download or read book Geologic Disposal of High Level Radioactive Waste written by Roland Pusch and published by CRC Press. This book was released on 2018-08-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geologic Disposal of High-Level Radioactive Waste examines the fundamental knowledge and conditions to be considered and applied by planners and other professionals when establishing national repository concepts, and constructing repositories for the long-term isolation of highly radioactive waste from surrounding crystalline rock. It emphasizes the important roles of structural geology, hydrogeology, hydrochemistry, and construction techniques. It specifically examines the disposal of steel canisters with spent reactor fuel in mined repositories (MR) at medium-depth, and in very deep boreholes (VDH). While disposal in mined repositories has been widely tested, the option of placing high-level radioactive waste in deep boreholes has been considered in the US, UK, and elsewhere in Europe, but has not yet been tested on a broad scale. This book examines the possibility of safe disposal for very long periods, proposing that the high salt content and density of groundwater at large depths are such that potentially contaminated water would not rise high enough to affect the more shallow biosphere. Features: Presents the best practices for disposal of spent fuel from nuclear reactors. Assesses waste isolation capacities in short- and long-term perspectives, and the associated risks. Describes site selection principles and the economics of construction of different types of repositories. Includes an appendix which provides the latest international recommendations and guidelines concerning the disposal of highly radioactive waste.
Download or read book Clay Microstructure written by Richard Bennett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plan of Review This review of clay microstructure is aimed at the diverse group of professionals who share an interest in the properties of fine-grained minerals in sediments. During the last several decades, members of this group have included geologists, soil scientists, soil engineers, engineering geologists, and ceramics scientists. More recently, it has included significant numbers of marine geologists and other engineers. Each of the disciplines has developed special techniques for investigating properties of clay sediments that have proven to be fruitful in answering questions of central interest. Knowledge of clay microstructure-the fabric of a sediment and the physico chemical interactions between its components-is fundamental to all these disciplines (Mitchell 1956; Lambe 1958a; Foster and De 1971). Clay fabric refers to the spatial distribution, orientations, and particle-to-particle relations of the solid particles (generally those less than 3. 9 /Lm in size) of sediment. Physico-chemical interac tions are expressions of the forces between the particles. In this review, we trace the historical development of under standing clay microstructure by discussing key scientific papers published before 1986 on physico-chemical interactions in fine grained sediments and on clay fabric. Since the development follows an intricate path, the current view of clay microstructure is summarized. This summary includes a discussion of the present state of knowledge, the observations made so far, and the facts that are now established.

Download or read book High Level Radioactive Waste HLW Disposal written by R. Pusch and published by WIT Press. This book was released on 2011-10-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Level Radioactive Waste (HLW) Disposal, A Global Challenge presents the most recent information on proposed methods of disposal for the most dangerous radioactive waste and for assessing their function from short- and long-term perspectives. It discusses new aspects of the disposal of such waste, especially HLW. The book is unique in the literature in making it clear that, due to tectonics and long-term changes in rock structure, rock can serve only as a ""mechanical support to the chemical apparatus"" and that effective containment of hazardous elements can only be managed by properly designed and manufactured containers (""canisters""). This contradicts the common belief that the rock itself is an effective barrier to the transport of contaminants like radionuclides. The importance of the longevity of the containers becomes clear and requires a consideration of all degrading physical/chemical processes, which occupies a considerable part of the book. The book is thus an important contribution to the literature because it proposes design principles that can make repositories for HLW radioactive waste much safer.

Download or read book Waste Management and the Environment VII written by C. A. Brebbia and published by WIT Press. This book was released on 2014-05-12 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the 7th International Conference on Waste Management and the Environment follows on from the success of previous meetings held in Cadiz (2002), Rhodes (2004), Malta (2006), Granada (2008), Tallin (2010) and the New Forest (2012). There is growing awareness of the detrimental effects of current waste disposal and a movement towards greater accountability for effective waste management. Better practices and safer solutions are required. This creates a need for more research on current disposal methods such as landfills, incineration, chemical and effluent treatment as well as recycling, waste incineration, clean technologies, waste monitoring, public and corporate awareness, and general education. Waste Management is one of the key problems of modern society due to the ever expanding volume and complexity of discarded domestic and industrial waste. Unfortunately many of the policies adopted in the past were aimed at short term solutions without due regard to the long term implications on health and the environment, leading in many cases to the need to take difficult and expensive remedial action. The desired direction of waste management is towards sustainable strategies. The approach which has emerged as the most sustainable strategy has been called 3Rs, where reduction, reuse and recycling, in this order, are seen as the best actions. Recently recovery is added as the fourth action (4Rs) applied in order to; for example, recover energy from waste that cannot be classified under the 3Rs. This largely decreases the volume of the waste that needs final disposal. Further steps are required towards improvement of current technologies, increased collaboration between the public, government and private sectors and increased involvement of all stakeholders. Topics covered include: Environmental impact; Reduce, reuse, recycle and recovery (4Rs); Cost and benefits of management options; Waste incineration and gasification; Energy from waste; Industrial waste management; Nuclear and hazardous waste; Agricultural waste; Wastewater; eWaste; Landfill optimization and mining; Remote sensing; Thermal treatment; Emergent pollutants; Environmental remediation; Legislation; Behavioural issues.
