Download or read book Deep Geological Disposal of Radioactive Waste written by W. R. Alexander and published by Elsevier. This book was released on 2011-07-29 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep Geological Disposal of Radioactive Waste presents a critical review of designing, siting, constructing and demonstrating the safety and environmental impact of deep repositories for radioactive wastes. It is structured to provide a broad perspective of this multi-faceted, multi-disciplinary topic: providing enough detail for a non-specialist to understand the fundamental principles involved and with extensive references to sources of more detailed information. Emphasis is very much on “deep geological disposal – at least some tens of metres below land surface and, in many cases, many hundred of metres deep. Additionally, only radioactive wastes are considered directly – even though such wastes often contain also significant chemotoxic or otherwise hazardous components. Many of the principles involved are generally applicable to other repository options (e.g. near-surface or on-surface disposal) and, indeed, to other types of hazardous waste. Presents a current critical review in designing, siting, constructing and demonsrating the safety and environmental impact of deep repositories for radwaste Addresses the fundamental principles of radioactive waste with up-to-date examples and real-world case studies Written for a multi-disciplinary audience, with an appropriate level of detail to allow a non-specialist to understand
Download or read book Deep Hole Drilling Feasibility Study written by Fenix & Scisson and published by . This book was released on 1969 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is feasible to drill a hole to a depth of 50,000 feet by utilizing conventional rotary drilling equipment and techniques. Existing equipment is capable of drilling the hole but modifications of some equipment items are warranted for completion of the lower portion of the hole. The whole could be started with presently available equipment as soon as funds are available, a location established, and a contractor selected. While the upper portion of the hole (20,000 - 30,000 ft.) is being drilled, equipment modifications could be made and supplemental equipment developed. This would allow time to make the equipment available when needed for the lower portion of the hole. Two locations are considered as established by the criteria, both in the Coast Ranges Province of California in the vicinity of the San Andreas Fault. One location would be in an area where granitic rock outcrops at the surface while the other would be in an area where the granitic is overlain by 10,000 feet of sediments. The estimated time to drill the hole under ideal conditions at either location is 4-3/4 years at an estimated cost of $20,000,000. [$400/ft].

This book was released on 2017-05-25 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological Repository Systems for Safe Disposal of Spent Nuclear Fuels and Radioactive Waste, Second Edition, critically reviews state-of-the-art technologies and scientific methods relating to the implementation of the most effective approaches to the long-term, safe disposition of nuclear waste, also discussing regulatory developments and social engagement approaches as major themes. Chapters in Part One introduce the topic of geological disposal, providing an overview of near-surface, intermediate depth, and deep borehole disposal, spanning low-, medium- and high-level wastes. Part Two addresses the different types of repository systems – crystalline, clay, and salt, also discussing methods of site surveying and construction. The critical safety issue of engineered barrier systems is the focus of Part Three, with coverage ranging from nuclear waste canisters, to buffer and backfill materials. Lastly, Parts Four and Five focus on safety, security, and acceptability, concentrating on repository performance assessment, then radiation protection, environmental monitoring, and social engagement. Comprehensively revised, updated, and expanded with 25% new material on topics of current importance, this is the standard reference for all nuclear waste management and geological repository professionals and researchers. Contains 25% more material on topics of current importance in this new, comprehensive edition Fully updated coverage of both near-surface/intermediate depth, and deep borehole disposal in one convenient volume Goes beyond the scientific and technical aspects of disposal to include the political, regulatory, and societal issues involved, all from an international perspective

Book excerpt: This is the final report on a project to update and improve the conceptual design of deep boreholes for high level nuclear waste disposal. The effort was concentrated on application to intact US legacy LWR fuel assemblies, but conducted in a way in which straightforward extension to other waste forms, host rock types and countries was preserved. The reference fuel design version consists of a vertical borehole drilled into granitic bedrock, with the uppermost kilometer serving as a caprock zone containing a diverse and redundant series of plugs. There follows a one to two kilometer waste canister emplacement zone having a hole diameter of approximately 40-50 cm. Individual holes are spaced 200-300 m apart to form a repository field. The choice of verticality and the use of a graphite based mud as filler between the waste canisters and the borehole wall liner was strongly influenced by the expectation that retrievability would continue to be emphasized in US and worldwide repository regulatory criteria. An advanced version was scoped out using zinc alloy cast in place to fill void space inside a disposal canister and its encapsulated fuel assembly. This excludes water and greatly improves both crush resistance and thermal conductivity. However the simpler option of using a sand fill was found adequate and is recommended for near-term use. Thermal-hydraulic modeling of the low permeability and porosity host rock and its small (≤ 1%) saline water content showed that vertical convection induced by the waste's decay heat should not transport nuclides from the emplacement zone up to the biosphere atop the caprock. First order economic analysis indicated that borehole repositories should be cost-competitive with shallower mined repositories. It is concluded that proceeding with plans to drill a demonstration borehole to confirm expectations, and to carry out priority experiments, such as retention and replenishment of in-hole water is in order.

Available in PDF, EPUB and Kindle. Book excerpt: A study to evaluate the suitability of large-diameter augered boreholes for the disposal of low-level and intermediate-level wastes at Bruce Nuclear Power Development site was begun in 1984. The disposal concept consists of augering 1.5-3.0 m boreholes to a desired depth, placing the waste containers at the base of the hole and backfilling the space around and above the containers with a material of low permeability. A concrete slab and a compacted clay cover placed over the backfilled borehole provides protection and proper surface drainage.This report summarizes the field instrumentation monitoring; the numerical analysis of heat dissipation from a large concrete plug into the surrounding soil medium; contaminant migration along a gap at the clay/concrete interface; and laboratory hydraulic conductivity testing of composite clay/grout samples.
