Book excerpt: The CIuster EDZ international conference and workshop on the 'Impact of the excavation disturbed or damaged zone (EDZ) on the performance of radioactive waste geological repositories' was jointly organised by the European Commission (EC) and ESV Euridice EIG, Belgium, in the framework of the EC Cluster Forum (CLub of Underground Storage, TEsting and Research facilities for radioactive waste disposal), in Luxembourg, from 3 to 5 November 2003. The Cluster EDZ conference had three main objectives: 1. to establish the present understanding of the nature and properties of EDZ; 2. to establish the consequences of the EDZ and propose remedial action for the different repository stages (from the design stage to the closure phase); 3. to assess the impact of the EDZ on the long-term performance of geological repositories. The present proceedings include the papers presented at, and the conclusions from, the Cluster EDZ conference and workshop as follows: 1. introductory keynote addresses on the relevance of the EDZ for post-closure safety of deep geological repositories, the conclusions of previous international workshops on the EDZ and the lessons learnt in each of the specific host-rock considered as potential formation to build a deep underground repository for radioactive waste (plastic and indurated clays, crystalIine rock and salt); 2. 12 oral presentations and 19 additional poster presentations; 3. a report from each working group discussion on the four hast-rock formations; and 4. a proposal for generic definitions of excavation disturbed and damaged zones and an overall synthesis and conclusions of the conference and workshop. The Cluster EDZ conference was attended by 145 participants from 20 countries (13 European Union Member States and candidate countries, and Switzerland (associated country to the Euratom research and training programme), six third countries (Canada, Croatia, India, Japan, South Africa and the United States of America)), and the OECD/NEA.

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 Geological Disposal of Radioactive Waste in Deep Clay Formations written by X.L. Li and published by Geological Society of London Special Publications. This book was released on 2023-09-01 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of research into the geological disposal of radioactive waste in Belgium, the HADES underground research laboratory (URL) was constructed in a clay formation in the early 1980s. This was the world's first purpose-built URL in a deep clay formation. Over the past four decades, the HADES URL has played an important role in the research, development and demonstration (RD&D) of geological disposal. It enabled the in situ characterization of the clay host rock, it allowed experiments to be performed under realistic geological conditions and it demonstrated the feasibility of constructing, operating and closing underground repositories. This volume presents several key contributions of the HADES URL to both Belgian and international research into geological disposal. It not only compiles some important RD&D results, but also illustrates the essential role URLs such as the HADES URL have played in developing concepts for the geological disposal of radioactive waste.
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 Underground Injection Science and Technology written by C-F. Tsang and published by Elsevier. This book was released on 2005-12-28 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapters by a distinguished group of international authors on various aspects of Underground Injection Science and Technology are organized into seven sections addressing specific topics of interest. In the first section the chapters focus on the history of deep underground injection as well regulatory issues, future trends and risk analysis. The next section contains ten chapters dealing with well testing and hydrologic modeling. Section 3, consisting of five chapters, addresses various aspects of the chemical processes affecting the fate of the waste in the subsurface environment. Consideration is given here to reactions between the waste and the geologic medium, and reactions that take place within the waste stream itself. The remaining four sections deal with experience relating to injection of, respectively, liquid wastes, liquid radioactive wastes in Russia, slurried solids, and compressed carbon dioxide. Chapters in Section 4, cover a diverse range of other issues concerning the injection of liquid wastes including two that deal with induced seismicity. In Section 5, Russian scientists have contributed several chapters revealing their knowledge and experience of the deep injection disposal of high-level radioactive liquid processing waste. Section 6 consists of five chapters that cover the technology surrounding the injection disposal of waste slurries. Among the materials considered are drilling wastes, bone meal, and biosolids. Finally, four chapters in Section 7 deal with questions relating to carbon dioxide sequestration in deep sedimentary aquifers. This subject is particularly topical as nations grapple with the problem of controlling the buildup of carbon dioxide in the atmosphere. * Comprehensive coverage of the state of the art in underground injection science and technology * Emerging subsurface waste disposal technologies * International scope

Download or read book Gas Generation and Migration in Deep Geological Radioactive Waste Repositories written by R.P. Shaw and published by Geological Society of London. This book was released on 2015-06-11 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the behaviour of gases in the context of radioactive waste disposal is a fundamental requirement in developing a safety case for the disposal of radioactive waste. Of particular importance are the long-term performance of bentonite buffers and cement-based backfill materials that may be used to encapsulate and surround the waste in a repository, and the behaviour of plastic clays, indurated mudrocks and crystalline formations that may be the host rocks for a repository. The EC Euratom programme funded project, FORGE, has provided new insights into the processes and mechanisms governing gas generation and migration with the aim of reducing uncertainty. This volume brings together papers on aspects of this topic arising from both the FORGE project and work undertaken elsewhere. This has been achieved by the acquisition of new experimental data coupled with modelling, through a series of laboratory and field-scale experiments performed at a number of underground research laboratories throughout Europe.
