This book was released on 1994 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: AECL Research is developing a concept for the permanent disposal of nuclear fuel waste in plutonic rock of the Canadian Shield. The Federal Environmental Assessment Review Panel has issued a set of guidelines to be used in preparing an environmental impact statement (EIS) that require the addressing of a number of microbiological factors and their potential to affect the integrity of the multiple barrier system on which the disposal concept is based. This report formulates views and positions on microbiological factors that could influence the performance of a disposal vault in plutonic rock. These include the presence and survival of microbes, biofilms, corrosion, biodegradation of emplaced materials, gas production, geochemical changes, radionuclide migration, colloid formation, mutation, pathogens, and methylation. Studies being performed to underscore and strengthen current knowledge are briefly discussed.
Book Synopsis Microbial Degradation Processes in Radioactive Waste Repository and in Nuclear Fuel Storage Areas by : J.H. Wolfram
Download or read book Microbial Degradation Processes in Radioactive Waste Repository and in Nuclear Fuel Storage Areas written by J.H. Wolfram and published by Springer Science & Business Media. This book was released on 1997-03-31 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose ofthe Workshop In the spirit of enhancing developments in science and technology by facilitating international scientific cooperation, the Science Committee of NATO is sponsoring AR W's in several selected priority areas. The objective of this workshop was to discuss what microbial mediated problems have been experienced in the area of nuclear waste management and spent fuel storage. Long term storage of high-level wastes in repositories is just starting in some countries. However, low and medium level wastes have been stored for several decades. In the area of spent fuel interim, storage has been extended at many locations far beyond the intended time. It was a priority of the workshop to examine and discuss what deleterious effects have been observed under these storage conditions or under conditions used in simulated trial tests for predicting material performance under the storage conditions. For example, one chronic problem that was discussed was possibility that microbial influenced corrosion (MIC) could be taking place in the wet storage of spent fuel thereby initiating or accelerating the process of corrosion. Another discussion in the area of waste forms, focused on the presence ofbiofilms which may be breaking down the structure of the waste form and thereby jeopardizing its integrity. The meeting focused on discussing the observations and data collected relating to problems encountered in the storage of these types of wastes, and sharing this information with others that have not monitored their facilities for similar problems.

Book Synopsis Natural Analogs in Support of the Canadian Concept for Nuclear Fuel Waste Disposal by : Jan J. Cramer
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 Synopsis The Microbiology of Nuclear Waste Disposal by : Jonathan R. Lloyd
Download or read book The Microbiology of Nuclear Waste Disposal written by Jonathan R. Lloyd and published by Elsevier. This book was released on 2020-10-22 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Microbiology of Nuclear Waste Disposal is a state-of-the-art reference featuring contributions focusing on the impact of microbes on the safe long-term disposal of nuclear waste. This book is the first to cover this important emerging topic, and is written for a wide audience encompassing regulators, implementers, academics, and other stakeholders. The book is also of interest to those working on the wider exploitation of the subsurface, such as bioremediation, carbon capture and storage, geothermal energy, and water quality. Planning for suitable facilities in the U.S., Europe, and Asia has been based mainly on knowledge from the geological and physical sciences. However, recent studies have shown that microbial life can proliferate in the inhospitable environments associated with radioactive waste disposal, and can control the long-term fate of nuclear materials. This can have beneficial and damaging impacts, which need to be quantified. - Encompasses expertise from both the bio and geo disciplines, aiming to foster important collaborations across this disciplinary divide - Includes reviews and research papers from leading groups in the field - Provides helpful guidance in light of plans progressing worldwide for geological disposal facilities - Includes timely research for planning and safety case development

The project participants also examined techniques for fuel characterization and advanced quality assessment/quality control. The key exercise included a round-robin experimental study on the measurements of fuel kernel and particle coating properties of recent Korean, South African and US coated particle productions applying the respective qualification measures of each participating Member State. The summary report documents the results and conclusions achieved by the project and underlines the added value to contemporary knowledge on HTGR fuel.
Book Synopsis An Assessment of the Feasibility of Indefinite Containment of Canadian Nuclear Fuel Wastes by : D. W. Shoesmith
Download or read book An Assessment of the Feasibility of Indefinite Containment of Canadian Nuclear Fuel Wastes written by D. W. Shoesmith and published by Pinawa, Man. : Whiteshell Laboratories. This book was released on 1995 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report analyzes the expected corrosion behavior of nuclear fuel waste containers in a conceptual Canadian disposal vault. The container materials considered are dilute titanium alloys and oxygen-free copper. The report presents various models that have been developed to predict container lifetimes, including the currently used model which does not take into account limitation of crevice corrosion and an outline of a model in which crevice corrosion is limited by repassivation. The disposal vault conditions considered change with time as the initially trapped oxygen is consumed and as the heat and radiation produced by the waste decay. The appendices contain detailed reassessments of the corrosion behavior of the two types of containers, in which model assumptions are examined and failure modes discussed.

Book Synopsis Safe Management of Wastes from Health-care Activities by : Yves Chartier
Download or read book Safe Management of Wastes from Health-care Activities written by Yves Chartier and published by World Health Organization. This book was released on 2014 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second edition of the WHO handbook on the safe, sustainable and affordable management of health-care waste--commonly known as "the Blue Book". The original Blue Book was a comprehensive publication used widely in health-care centers and government agencies to assist in the adoption of national guidance. It also provided support to committed medical directors and managers to make improvements and presented practical information on waste-management techniques for medical staff and waste workers. It has been more than ten years since the first edition of the Blue Book. During the intervening period, the requirements on generators of health-care wastes have evolved and new methods have become available. Consequently, WHO recognized that it was an appropriate time to update the original text. The purpose of the second edition is to expand and update the practical information in the original Blue Book. The new Blue Book is designed to continue to be a source of impartial health-care information and guidance on safe waste-management practices. The editors' intention has been to keep the best of the original publication and supplement it with the latest relevant information. The audience for the Blue Book has expanded. Initially, the publication was intended for those directly involved in the creation and handling of health-care wastes: medical staff, health-care facility directors, ancillary health workers, infection-control officers and waste workers. This is no longer the situation. A wider range of people and organizations now have an active interest in the safe management of health-care wastes: regulators, policy-makers, development organizations, voluntary groups, environmental bodies, environmental health practitioners, advisers, researchers and students. They should also find the new Blue Book of benefit to their activities. Chapters 2 and 3 explain the various types of waste produced from health-care facilities, their typical characteristics and the hazards these wastes pose to patients, staff and the general environment. Chapters 4 and 5 introduce the guiding regulatory principles for developing local or national approaches to tackling health-care waste management and transposing these into practical plans for regions and individual health-care facilities. Specific methods and technologies are described for waste minimization, segregation and treatment of health-care wastes in Chapters 6, 7 and 8. These chapters introduce the basic features of each technology and the operational and environmental characteristics required to be achieved, followed by information on the potential advantages and disadvantages of each system. To reflect concerns about the difficulties of handling health-care wastewaters, Chapter 9 is an expanded chapter with new guidance on the various sources of wastewater and wastewater treatment options for places not connected to central sewerage systems. Further chapters address issues on economics (Chapter 10), occupational safety (Chapter 11), hygiene and infection control (Chapter 12), and staff training and public awareness (Chapter 13). A wider range of information has been incorporated into this edition of the Blue Book, with the addition of two new chapters on health-care waste management in emergencies (Chapter 14) and an overview of the emerging issues of pandemics, drug-resistant pathogens, climate change and technology advances in medical techniques that will have to be accommodated by health-care waste systems in the future (Chapter 15).

Book Synopsis Environmental Consequences of the Chernobyl Accident and Their Remediation by : International Atomic Energy Agency
Download or read book Environmental Consequences of the Chernobyl Accident and Their Remediation written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.
