Download or read book Assessment of the Performance of Engineered Waste Containment Barriers written by National Research Council and published by National Academies Press. This book was released on 2007-09-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.
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 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 Fire Retardancy Behavior of Polymer Clay Nanocomposites written by Indraneel Suhas Zope and published by Springer. This book was released on 2018-05-16 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the early ignition behavior of polymer/clay nanocomposites, which are perceived as potential eco-friendly flame retardant systems. It examines the correlation between clay structural chemistry and high-temperature transformations with clay-assisted decomposition of organic macromolecules. In particular, it investigates the unique effects of metal ions like Mg2+, Al3+ and Fe3+ that are inherent in clays (smectite) on the combustion and thermo-oxidative decomposition of polyamide 6. The results indicate that metal ions present on/in montmorillonite platelets have preferential reactivity towards peroxy/alkoxy groups during polyamide 6 thermal decomposition. Lastly, a simple solution in the form of a physical coating on clay surface is proposed, based on the role of polymer–clay interfacial interaction.
Download or read book Environmental Soil Properties and Behaviour written by Raymond N. Yong and published by CRC Press. This book was released on 2012-03-05 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: From bridges and tunnels to nuclear waste repositories, structures require that soils maintain their design engineering properties if the structures are to reach their projected life spans. The same is true for earth dams, levees, buffers, barriers for landfills, and other structures that use soils as engineered materials. Yet soil, a natural resource, continues to change as a result of natural and anthropogenic stresses. As the discipline of soil properties and behaviours matures, new tools and techniques are making it possible to study these properties and behaviours in more depth. What Happens to Soil Under Weathering, Aging, and Chemical Stress? Environmental Soil Properties and Behaviour examines changes in soil properties and behaviour caused by short- and long-term stresses from anthropogenic activities and environmental forces. Introducing new concepts of soil behaviour, soil maturation, and soil functionality, it integrates soil physics, soil chemistry, and soil mechanics as vital factors in soil engineering. The book focuses on environmental soil behaviour, with particular attention to two main inter-related groups of soil–environment issues. The first is the use of soil as an environmental tool for management and containment of toxic and hazardous waste materials. The second is the impact of ageing and weathering processes and soil contamination on the properties and behaviour of soils, especially those used in geotechnical and geoenvironmental engineering projects. A Transdisciplinary Look at Soil-Changing Processes To determine short- and long-term soil quality and soil functionality, the authors emphasize the need to be aware of the nature of the stressors involved as well as the kinds of soil-changing processes that are evoked. This book takes a first step toward a much-needed transdisciplinary effort to develop a broader and deeper understanding of what happens to soil and how we can determine and quantify the effect of biogeochemical processes. It offers a timely resource for the study of soil properties and behaviours, effects of environmental changes, and remediation of contaminated soil.

Download or read book Trust in Construction Projects written by Anita Cerić and published by Routledge. This book was released on 2015-12-14 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between project managers representing project owners and those on the contractor side is often threatened by communication risk. The main communication risk minimization strategy in the construction phase is trust, which plays a major role in the success of key working relationships across the construction industry. This book investigates this phenomenon, and goes on to show that once developed, trust outshines all other strategies of communication risk minimization and is essential for project success. As part of this investigation, communication risk in construction projects is examined in detail, with a particular focus on the effects of information asymmetry on working relationships. Drawing on many years of empirical research involving project managers working internationally, Trust in Construction Projects also provides strategies to minimize information asymmetries in order to build trust, and ensure the success of construction projects. By increasing understanding of trust in construction projects, this book adds an important new perspective to the fields of construction management and project management. This is essential reading for researchers and students, as well as practitioners in these fields.

Download or read book Sustainable Engineering written by Catherine Mulligan and published by CRC Press. This book was released on 2019-01-30 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Engineering: Principles and Implementation provides a comprehensive overview of the interdisciplinary field of sustainability as it applies to engineering and methods for implementation of sustainable practices. Due to increasing constraints on resources and on the environment and effects of climate change, engineers are being faced with new challenges. While it is generally believed that the concepts of sustainable design must be adhered to so that future generations may be protected, the execution and practice of these concepts are very difficult. It is therefore the focus of this book to give both a conceptual understanding as well as practical skills to apply sustainable engineering principles to engineering design. This book introduces relevant theory, principles, and ethical expectations for engineers, presents concepts related to industrial ecology, green engineering, and eco-design, and details frameworks that indicate the challenges and constraints of applying sustainable development principles. It describes the tools, protocols, and guidelines that are currently available through case studies and examples from around the world. The book is designed to be used by undergraduate and graduate students in any engineering program (with particular emphasis on civil, environmental and chemical engineering) and other programs in which sustainability is taught, in addition to practicing scientists and engineers and all others concerned with the sustainability of products, projects and processes. Specific Features: Discusses sources of contaminants and their impact on the environment Addresses sustainable assessment techniques, policies, protocols and guidelines Describes new tools and technologies for achieving sustainable engineering Includes social and economic sustainability dimensions Offers case studies demonstrating implementation of sustainable engineering practices
