This book was released on 1990 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: For high level and alpha bearing radioactive wastes, the disposal concept most generally agreed upon is the emplacement of the conditioned waste in deep underground respositories in stable geological formations. The report reflects the general consensus that long lived radioactive wastes can be isolated safely from human environment in such repositories located in deep, geological formations. One of the most important tasks in the development of underground disposal systems is the plugging of boreholes and the sealing of shafts excavated for either exploratory or operational purposes. Several countries have outlined proposals and identified geological formations for detailed examination as potential host media for waste repositories.

This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sealing of boreholes and underground excavations has not received much engineering attention until fairly recently. The growing awareness of and sensitivity to environmental concerns of the technical community as well as of the public at large has resulted in an increasing recognition of the fact that these geological penetrations may have an environmental impact. The issue of possible contamination resulting from migration along boreholes, adits, shafts or tunnels unquestionably has been raised most forcefully with in the context of nuclear waste disposal. Several nuclear waste disposal programs, notably the Civilian and the Defence programs of the US De partment of Energy, the US Nuclear Regulatory Commission and the Canadian and Swedish radioactive waste disposal programs have conducted major research efforts aimed at developing adequate seal designs for penet rations in host rock formations for high-level nuclear waste repositories. While a considerable data base has been gathered over the last two decades or so with regard to the performance of seals, most of the information is presented in research reports and widely scattered papers in journals and proceedings of conferences. Hence, the materials are not readily accessible to potential users such as designers, contractors or regulators who are not familiar with nuclear waste disposal programs.

The project was funded by the European Commission and the national governments and authorities. The project extends the basis for optimising repository design and construction and for predicting long-term performance of barriers in a salt repository for radioactive waste. The research includes in-situ investigations, laboratory experiments, forensic examinations, computational simutations and desk studies. In-situ investigations were conducted in the Asse salt mine subsequent to completion of the large-scale experiment 'TSDE' (Thermal simulation of drift emplacement) in wich six disposal cask mock-ups were heated for over eight years. Two disposal cask mock-ups and a large number of instruments were recovered, cores retrieved, and geophysical studies were conducted. Laboratory tests evaluated properties of the backfill and the rock salt, inckuding the disturbed zone. Physical, mechanical and hydrological experiments quantified parameter values requisite for material models and described attributes of backfill and rock salt at advanced stages of compaction and deformation. Post-test examination of candidate container material samples recovered from the TSDE test drift exhibited minimal corrosion. Modelling studies analysed the thermomechanical evolution of the TSDE experiment and evaluated extant predictive capabilities. Computational results compared favourably with in-situ experimental results including temperature profiles, stress distributions, displacements and the attendant properties of compacted backfill, intact rock salt and the excavation damage zone. Desk stidues addressed retrieval issues and documented the scientific and technical results of the entire TSDE project (1985 to 2002).
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.
Download or read book Disposition of High Level Waste and Spent Nuclear Fuel written by National Research Council and published by National Academies Press. 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.
Download or read book Disposal of All Forms of Radioactive Waste and Residues written by Michael Lersow and published by Springer Nature. This book was released on 2019-11-16 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes repository solutions for all types of radioactive waste and residues in different geotechnical repository structures. The focus is initially on existing or planned final disposal sites in Germany and the process of finding sites. However, international comparisons are drawn, especially to locations in the US. This affects both the repository structures and the legal requirements. The radioactive substances considered include residues from uranium ore processing, as well as low and intermediate level radioactive waste up to heat generating, high level radioactive wastes, such as spent fuel and vitrified waste from reprocessing. In order to evaluate the repository structures and their inventories, a dimensionless radiotoxicity index Ai / Fi [activity of radionuclide quantity (Ai) related to the exemption limit of radionuclide (Fi)] has been introduced. This gives the reader a well-founded overview of the degree of inconsistency in the handling of safety requirements for the respective geotechnical environmental structures. This creates the necessary transparency on this issue, which has not been previously available and is required by stakeholders today. The long-term security, the duration of the observation period and the certainty of the safety prognosis are also discussed in the book as well as the participation of subsequent generations in current and possible future repositories. This is vital as nuclear energy will continue to be used worldwide in the long term. The international repository projects presented have all been subjected to the same evaluation criteria. This applies both to existing operational project as well as those about to be commissioned and the processes for seeking locations. Special attention has been paid to monitoring, both operational and long-term monitoring. This broad range of topics makes this book a very valuable read for both the interested public and the professional world.
