Geologic isolation of high-level nuclear waste from the biosphere requires special consideration in countries at high latitudes (>40°N) owing to the possibility of future episodes of continental glaciation (Talbot ). It is now widely recognized that Pleistocene continental glaciations have had a profound effect on rates of sediment erosion (Cuffey & Paterson ) and deformation. Nuclear waste is currently a significant political issue in Western Europe and North America and is becoming increasingly important in all other countries with existing or planned nuclear programmes. This is the first book to tackle in a comprehensive and integrated fashion the problems associated with the geological disposal of nuclear waste. cal approach to geologic isolation A geologic isolation system is much more than a site for disposal or dumping of radioactive waste. It is a system that consists of three principal elements: geologic setting, engineered barriers, and sealing systems. These elements must work together to isolate the waste as completely as possible. 1. 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.
Abstract. The authors consider the future of nuclear power in terms of radioactive waste management. The presentation tackles the subject in a detailed and integrated manner while making the information accessible both to those involved in the field and to the non-scientific reader. Predictive Geology: With Emphasis on Nuclear-Waste Disposal covers the proceedings of papers presented at sessions sponsored by the International Association for Mathematical Geology. The topics that this book tackles are issues relevant to nuclear-waste disposal. The first chapter discusses the use of plate tectonics as a catastrophe theoretic. Assessment of effectiveness of geologic isolation systems. Geologic factors in the isolation of nuclear waste: evaluation of long-term geomorphic processes and catastrophic events. waste in deep underground geological formations. The safe long-term sealing off of the waste in a repository, and its isolation from the biosphere, are guaranteed by a multi-barrier system consisting of geological and engineered barriers. The geology of the host rock is a crucial factor in this concept.
The concept of deep geological repositories for the long-term storage of nuclear waste relies on the following assumptions: (1) rock mass—and the associated stability of the physical, hydrological, and chemical environment—will constitute the primary physical barrier and part of the chemical and transport barriers for radionuclide isolation. INTERNATIONAL ATOMIC ENERGY AGENCY, Geological Disposal Facilities for Radioactive Waste, IAEA Safety Standards Series No. SSG, IAEA, Vienna (). This Safety Guide provides guidance on prevailing good practices for meeting and demonstrating compliance with, . Isolation in a geologic setting has been the generally favored solution to the high-level radioactive waste (HLW) problem since a scientific basis for nuclear waste management began to be. stable geological formations have isolated radionuclides for many millions of years. Objectives The main objective of this document is to summarize the basic principles and approaches to siting, design and construction of a deep geological repository for disposal of high level and alpha bearing.
