Download or read book Assessment of Contaminated Brine Fate and Transport in MB139 at WIPP written by and published by . This book was released on 2014 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the radionuclide release event of February 14, 2014 at the Waste Isolation Pilot Plant (WIPP), actinide contamination has been found on the walls and floor in Panel 7 as a result of a release in Room 7 of Panel 7. It has been proposed to decontaminate Panel 7 at the WIPP by washing contaminated surfaces in the underground with fresh water (Nelson, 2014a). A cost-effective cleanup of this contamination would allow for a timely return to waste disposal operations at WIPP. It is expected that the fresh water used to decontaminate Panel 7 will flow as contaminated brine down into the porosity of the materials under the floor - the run-of-mine (ROM) salt above Marker Bed 139 (MB139) and MB139 itself - where its fate will be controlled by the hydraulic and transport properties of MB139. Due to the structural dip of MB139, it is unlikely that this brine would migrate northward towards the Waste-Handling Shaft sump. A few strategically placed shallow small-diameter observation boreholes straddling MB139 would allow for monitoring the flow and fate of this brine after decontamination. Additionally, given that flow through the compacted ROM salt floor and in MB139 would occur under unsaturated (or two-phase) conditions, there is a need to measure the unsaturated flow properties of crushed WIPP salt and salt from the disturbed rock zone (DRZ).
Download or read book Modeling Gas and Brine Migration for Assessing Compliance of the Waste Isolation Pilot Plant written by and published by . This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the request of the WIPP Project Integration Office (WPIO) of the DOE, the WIPP Performance Assessment (PA) Department of Sandia National Laboratories (SNL) has completed preliminary uncertainty and sensitivity analyses of gas and brine migration away from the undisturbed repository. This paper contains descriptions of the numerical model and simulations, including model geometries and parameter values, and a summary of major conclusions from sensitivity analyses. Because significant transport of contaminants can only occur in a fluid (gas or brine) medium, two-phase flow modeling can provide an estimate of the distance to which contaminants can migrate. Migration of gas or brine beyond the RCRA ''disposal-unit boundary'' or the Standard's accessible environment constitutes a potential, but not certain, violation and may require additional evaluations of contaminant concentrations.

Download or read book Advances in Hydrogeology written by Phoolendra K. Mishra and published by Springer Science & Business Media. This book was released on 2013-04-16 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents different types of progress in hydrogeology, including conceptualization changes, different approaches to simulating groundwater flow and transport new hydrogeophysical methods. Each chapter extends or summarizes a recent development in hydrogeology, with forward-looking statements regarding the challenges and strengths that are faced. While the title and scope is broad, there are several sub-themes that connect the chapters. Themes include theoretical advances in conceptualization and modeling of hydrogeologic problems. Conceptual advances are further tempered by insights arising from observations from both field and laboratory work.
Download or read book Geological Repository Systems for Safe Disposal of Spent Nuclear Fuels and Radioactive Waste written by Michael J Apted and published by Woodhead Publishing. 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

Download or read book Household Waste Recycling written by Richard Waite and published by Routledge. This book was released on 2013-11-05 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Households in the UK each generate around one tonne of waste per year, and the successful management and disposal of this waste is becoming an increasingly important issue. In many cases, recycling is the most sensible option, and the UK government has set a target to recycle a quarter of all household waste by the year 2000. This book gives an overview of the waste management and disposal options currently available, and provides a comprehensive and up-to-date analysis of how recycling could develop. The author – one of the UK's leading experts – looks at how much of the waste is potentially recyclable, shows the various ways in which recyclable materials can be separated and reprocessed, and assesses the existing markets for recyclable materials. He gives an in-depth account of the important subject of packaging recycling, and compares the UK's progress and performance with what is happening elsewhere in Europe. He also discusses how the performance of current recycling schemes can be measured and costed, and forecasts future developments in the industry. Dr Richard Waite is a former Specialist Advisor to the House of Commons Environment Select Committee and is currently a consultant with Coopers & Lybrand. He established one of the first commercial MRFs in the country, and has advised many local authorities, central government departments (including the European Commission) and private sector organisations on recycling issues.
