Book excerpt: SRI International has projected the rate, duration, and magnitude of geomorphic processes and events in the Southwest and Gulf Coast over the next million years. This information will be used by the Department of Energys̀ Pacific Northwest Laboratory (PNL) as input to a computer model, which will be used to simulate possible release scenarios and the consequences of the release of nuclear waste from geologic containment. The estimates in this report, although based on best scientific judgment, are subject to considerable uncertainty. An evaluation of the Quaternary history of the two study areas revealed that each had undergone geomorphic change in the last one million years. Catastrophic events were evaluated in order to determine their significance to the simulation model. Given available data, catastrophic floods are not expected to occur in the two study areas. Catastrophic landslides may occur in the Southwest, but because the duration of the event is brief and the amount of material moved is small in comparison to regional denudation, such events need not be included in the simulation model. Ashfalls, however, could result in removal of vegetation from the landscape, thereby causing significant increases in erosion rates. Because the estimates developed during this study may not be applicable to specific sites, general equations were presented as a first step in refining the analysis. These equations identify the general relationships among the important variables and suggest those areas of concern for which further data are required. If the current model indicates that geomorphic processes (taken together with other geologic changes) may ultimately affect the geologic containment of nuclear waste, further research may be necessary to refine this analysis for application to specific sites.

Available in PDF, EPUB and Kindle. Book excerpt: 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, hydrogeology, hydrochemistry, and construction techniques. It specifically examines the disposal of steel canisters with spent reactor fuel in mined repositories (MR) at medium-depth, and in very deep boreholes (VDH). While disposal in mined repositories has been widely tested, the option of placing high-level radioactive waste in deep boreholes has been considered in the US, UK, and elsewhere in Europe, but has not yet been tested on a broad scale. This book examines the possibility of safe disposal for very long periods, proposing that the high salt content and density of groundwater at large depths are such that potentially contaminated water would not rise high enough to affect the more shallow biosphere. Features: Presents the best practices for disposal of spent fuel from nuclear reactors. Assesses waste isolation capacities in short- and long-term perspectives, and the associated risks. Describes site selection principles and the economics of construction of different types of repositories. Includes an appendix which provides the latest international recommendations and guidelines concerning the disposal of highly radioactive waste.

Book excerpt: 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 model, and the second chapter covers geologic predictions and radioactive waste disposal. Chapter 3 also talks about radioactive waste disposal, with emphasis on the application of predictive geology. Chapter 4 discusses salt domes and Chapter 5 tackles the use of fault-tree analysis for probabilistic assessment of radioactive-waste segregation. The sixth chapter covers predictive geology in nuclear-waste management, while the seventh chapter tackles nuclear power on unstable ground. The eighth chapter deals with long-term thermohydrologic behavior of nuclear-waste repositories. Chapter 9 discusses the influence of faulting on groundwater flow and contaminant transport, while chapter 10 covers the influence of microfissures in crystalline rock on radionuclide migration. The eleventh chapter tackles the long-term prediction of the fate of nuclear waste deeply buried in granite, and the twelfth chapter talks about the use of quantitative evaluation of the contribution of geologic knowledge in exploration for petroleum. The last chapter deals with resource-estimation models and predicted discovery. Researchers and professionals concerned with the effects of radioactive materials to the environment will find this book a great source of information.

This book was released on 2001-07-05 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focused attention by world leaders is needed to address the substantial challenges posed by disposal of spent nuclear fuel from reactors and high-level radioactive waste from processing such fuel. The biggest challenges in achieving safe and secure storage and permanent waste disposal are societal, although technical challenges remain. Disposition of radioactive wastes in a deep geological repository is a sound approach as long as it progresses through a stepwise decision-making process that takes advantage of technical advances, public participation, and international cooperation. Written for concerned citizens as well as policymakers, this book was sponsored by the U.S. Department of Energy, U.S. Nuclear Regulatory Commission, and waste management organizations in eight other countries.

Book excerpt: The Scope of Work undertaken covers three main tasks, described as follows: (Task 1) CDM provided consulting services to the University on modeling aspects of the study having to do with transport processes involving the local groundwater system near the repository and the flow of fluids and vapors through the various porous media making up the repository system. (Task 2) CDM reviewed literature related to repository design, concentrating on effects of the repository geometry, location and other design factors on the flow of fluids within the repository boundaries, drainage from the repository structure, and the eventual transport of radionucldies away from the repository site. (Task 3) CDM, in a joint effort with LLL personnel, identified generic boundary and initial conditions, identified processes to be modeled, and recommended a modeling approach with suggestions for appropriate simplifications and approximations to the problem and identifiying important parameters necessary to model the processes. This report consists of two chapters and an appendix. The first chapter (Chapter III of the LLL report) presents a detailed description and discussion of the modeling approach developed in this project, its merits and weaknesses, and a brief review of the difficulties anticipated in implementing the approach. The second chapter (Chapter IV of the LLL report) presents a summary of a survey of researchers in the field of repository performance analysis and a discussion of that survey in light of the proposed modeling approach. The appendix is a review of the important physical processes involved in the potential hydrologic transport of radionuclides through, around and away from deep geologic nuclear waste repositories.
