Book Description

The vapor pressure of uranium hexafluoride, has been determined from 0 deg C to 85 deg C in a copper apparatus. The data obtained are given by the two equations log 10 P mm Hg = 2623.3/T + 10.8407 (solid, vapor), log 10 P mm Hg = -1505.9/T + 7.5223 (liquid, vapor) and the latent heats are: delta H sub sub = 12.00 kg-cal, delta H sub vap = 6.89 kg-cal. The experimental arrangement is shown in Figure 1. This consists of a reservoir A in a thermostat and a brass sylphon bellows for the measurement of pressure by a null method. The pressure above an atmosphere was read on a multiple mercury manometer using dibutylphthalate as a piston liquid. p2.

Book Description

With the narrative punch of Jonathan Harr’s A Civil Action and the commitment to environmental truth-telling of Erin Brockovich, The Fluoride Deception documents a powerful connection between big corporations, the U.S. military, and the historic reassurances of fluoride safety provided by the nation’s public health establishment. The Fluoride Deception reads like a thriller, but one supported by two hundred pages of source notes, years of investigative reporting, scores of scientist interviews, and archival research in places such as the newly opened files of the Manhattan Project and the Atomic Energy Commission. The book is nothing less than an exhumation of one of the great secret narratives of the industrial era: how a grim workplace poison and the most damaging environmental pollutant of the cold war was added to our drinking water and toothpaste.

Book Description

Originally published in 1983, this book presents both the technical and political information necessary to evaluate the emerging threat to world security posed by recent advances in uranium enrichment technology. Uranium enrichment has played a relatively quiet but important role in the history of efforts by a number of nations to acquire nuclear weapons and by a number of others to prevent the proliferation of nuclear weapons. For many years the uranium enrichment industry was dominated by a single method, gaseous diffusion, which was technically complex, extremely capital-intensive, and highly inefficient in its use of energy. As long as this remained true, only the richest and most technically advanced nations could afford to pursue the enrichment route to weapon acquisition. But during the 1970s this situation changed dramatically. Several new and far more accessible enrichment techniques were developed, stimulated largely by the anticipation of a rapidly growing demand for enrichment services by the world-wide nuclear power industry. This proliferation of new techniques, coupled with the subsequent contraction of the commercial market for enriched uranium, has created a situation in which uranium enrichment technology might well become the most important contributor to further nuclear weapon proliferation. Some of the issues addressed in this book are: A technical analysis of the most important enrichment techniques in a form that is relevant to analysis of proliferation risks; A detailed projection of the world demand for uranium enrichment services; A summary and critique of present institutional non-proliferation arrangements in the world enrichment industry, and An identification of the states most likely to pursue the enrichment route to acquisition of nuclear weapons.

Book Description

Fluorine: A Paradoxical Element, Volume Five, deals with the link between fluorine, humanity and the environment. It is divided into three main sections, including i) The history and developmental stages of fluorinated products, ii) Awareness of its importance in our environment, and iii) Recent contributions of fluoride products in medicine, pharmacy and our daily lives. Made engaging through interesting figures and accessible language, and written by a leading expert, Professor Tressaud, the book supports the work of scientists working in materials, toxicology and environmental science. It complements the author's edited series, Progress in Fluorine Science, covering recent advances. - Describes background and contextual information regarding the history, development of understanding, and applications of this important element - Explores the impacts of fluorine, both positive and negative, in the environment and biological systems - Includes applied, real-world information from agencies, such as CNRS, NASA, HWS and DOH

Book Description

The production of nuclear materials for the national defense was an intense, nationwide effort that began with the Manhattan Project and continued throughout the Cold War. Now many of these product materials, by-products, and precursors, such as irradiated nuclear fuels and targets, have been declared as excess by the Department of Energy (DOE). Most of this excess inventory has been, or will be, turned over to DOE's Office of Environmental Management (EM), which is responsible for cleaning up the former production sites. Recognizing the scientific and technical challenges facing EM, Congress in 1995 established the EM Science Program (EMSP) to develop and fund directed, long-term research that could substantially enhance the knowledge base available for new cleanup technologies and decision making. The EMSP has previously asked the National Academies' National Research Council for advice for developing research agendas in subsurface contamination, facility deactivation and decommissioning, high-level waste, and mixed and transuranic waste. For this study the committee was tasked to provide recommendations for a research agenda to improve the scientific basis for DOE's management of its high-cost, high-volume, or high-risk excess nuclear materials and spent nuclear fuels. To address its task, the committee focused its attention on DOE's excess plutonium-239, spent nuclear fuels, cesium-137 and strontium-90 capsules, depleted uranium, and higher actinide isotopes.

Book Description

Understanding radionuclide behaviour in the natural environment is essential to the sustainable development of the nuclear industry and key to assessing potential environmental risks reliably. Minimising those risks is essential to enhancing public confidence in nuclear technology. Scientific knowledge in this field has developed greatly over the last decade.Radionuclide behaviour in the natural environment provides a comprehensive overview of the key processes and parameters affecting radionuclide mobility and migration.After an introductory chapter, part one explores radionuclide chemistry in the natural environment, including aquatic chemistry and the impact of natural organic matter and microorganisms. Part two discusses the migration and radioecological behavior of radionuclides. Topics include hydrogeology, sorption and colloidal reactions as well as in-situ investigations. Principles of modelling coupled geochemical, transport and radioecological properties are also discussed. Part three covers application issues: assessment of radionuclide behaviour in contaminated sites, taking Chernobyl as an example, estimation of radiological exposure to the population, performance assessment considerations related to deep geological repositories, and remediation concepts for contaminated sites.With its distinguished editors and international team of expert contributors, Radionuclide behaviour in the natural environment is an essential tool for all those interested or involved in nuclear energy, from researchers, designers and industrial operators to environmental scientists. It also provides a comprehensive guide for academics of all levels in this field. - Provides a comprehensive overview of the key processes and parameters affecting radionuclide mobility and migration - Explores radionuclide chemistry in the natural environment - Discusses the migration and radioecological behaviour of radionuclides
