Book Natural Analogues in Radioactive Waste Disposal

Download or read book Natural Analogues in Radioactive Waste Disposal written by B. Come and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to validate predictive models of the very long-term processes which affect the performance of radioactive waste repositories, there has been an increased interest in the information and understanding which can be obtained from studying similar mechanisms in natural systems. These "natural analogues", as they are known in the jargon of waste management, have been studied sporadically for many years, but there has been a considerable rejuvenation of interest in the last four years, possibly owing to the fact that performance assessment methodolo gy is gradually maturing to the point where it needs the kind of support which analogues can offer. Since 1982, the Commission of the European Communities has been involved in specific work on natural analogues in the framework of its activities on radioactive waste management, principally within the MIRAGE project which concerns migration of radionuclides in the geosphere. As a consequence, the Commission took the initiative, in 1985, of establish ing a Natural Analogue Working Group (NAWG) whose members can benefit from the overall expertise available for managing their own natural analogue research programmes. In this group, modeller' s requirements and the results of field research are exchanged at regular intervals. A number of wide-ranging investigation programmes, both on national and international scales. are currently underway or being initiated, and several of these have been discussed recently at the NAWG.

Book Natural Analogue Studies in the Geological Disposal of Radioactive Wastes

Download or read book Natural Analogue Studies in the Geological Disposal of Radioactive Wastes written by W.M. Miller and published by Elsevier. This book was released on 2011-08-18 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first purpose of this book is to provide a comprehensive review of the state of development of natural analogue studies with emphasis on those studies which are relevant to the following repository designs: Nagra (Switzerland) disposal concepts for high-level waste/low and intermediate-level waste; SKB (Sweden) disposal concepts for spent fuel/low and intermediate-level waste; and Nirex (UK) disposal concept for low and intermediate-level waste. The book's second aim is to discuss the expanding application of natural analogues for non-performance assessment purposes, especially their potential for presenting the concept of geological disposal to various interested audiences in a coherent, understandable and scientifically legitimate manner. Much of the discussion of the book is relevant to concepts for geological disposal of radioactive wastes by other countries, and is concerned only with those physico-chemical processes which control the release of radionuclides from the near-field, and their subsequent retardation and transport in the geosphere.

Book Geological Disposal of Radioactive Wastes and Natural Analogues

Download or read book Geological Disposal of Radioactive Wastes and Natural Analogues written by W. Miller and published by Elsevier. This book was released on 2000-11-09 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many countries are currently exploring the option to dispose of highly radioactive solid wastes deep underground in purpose built, engineered repositories. A number of surface and shallow repositories for less radioactive wastes are already in operation. One of the challenges facing the nuclear industry is to demonstrate confidently that a repository will contain wastes for so long that any releases that might take place in the future will pose no significant health or environmental risk. One method for building confidence in the long-term future safety of a repository is to look at the physical and chemical processes which operate in natural and archaeological systems, and to draw appropriate parallels with the repository. For example, to understand why some uranium orebodies have remained isolated underground for billions of years. Such studies are called 'natural analogues'. This book investigates the concept of geological disposal and examines the wide range of natural analogues which have been studied. Lessons learnt from studies of archaeological and natural systems can be used to improve our capabilities for assessing the future safety of a radioactive waste repository.

Book Natural Analogues in Performance Assessments for the Disposal of Long Lived Radioactive Wastes

Download or read book Natural Analogues in Performance Assessments for the Disposal of Long Lived Radioactive Wastes written by International Atomic Energy Agency and published by . This book was released on 1989 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique and scientifically most difficult aspect of predictive safety analysis of repositories for long lived wastes is the extrapolation of short term field and laboratory data to the long periods of time required by regulatory agencies for performance assessment. Natural analogues may be the only way of obtaining data on the cumulative effect of the migration of radionuclides over the time-scales of interest. This report briefly summarizes the state of the art in this field for technical specialists and may also serve as an introduction to the subject for managers.

Book Natural Analogs in Support of the Canadian Concept for Nuclear Fuel Waste Disposal

Download or read book Natural Analogs in Support of the Canadian Concept for Nuclear Fuel Waste Disposal written by Jan J. Cramer and published by Pinawa, Man. : Whiteshell Laboratories. This book was released on 1994 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data used for the assessment modelling of the Canadian concept for disposal of nuclear fuel waste is mainly based on observations from short-term laboratory and field experiments, although it must apply to periods of 10,000 to one million years. Natural analogs can provide useful data and a qualitative illustration of the interaction of processes and materials in complex natural systems. This report reviews the available natural analog information used in support of the Canadian concept, with particular emphasis on the disposal of used CANDU fuel. The report gives a definition of natural analogs and an overview of the various types of analogs and analog studies; describes the main components of the disposal system, including the vault, the geosphere, and the biosphere, and gives specific examples for each; and describes several comprehensive natural systems that contain a number of features and processes similar to the disposal concept and that are under study by other countries as part of their waste disposal management programs.

Book Radioactive Waste Repository Licensing

Download or read book Radioactive Waste Repository Licensing written by Board on Radioactive Waste Management and published by . This book was released on 1992-02 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book recounts the issues raised and the viewpoints aired at a recent symposium on repository licensing. It summarizes the problems surrounding the setting of an Environmental Protection Agency standard for the release of radionuclides and the regulatory problems inherent in meeting such a standard. Symposium participants came from a variety of federal agencies and advisory groups, state governments, public interest groups, engineering firms, national laboratories, and foreign and international organizations. The book illustrates the strong feeling in the radioactive waste disposal community that changes must be made if the United States is to fulfill its promise of safe management of current and future nuclear waste.
