Update on the Chemical Thermodynamics of Uranium, Neptunium, Plutonium, Americium and Technetium


Book Description

This volume is part of the series on "Chemical Thermodynamics", published under the aegis of the OECD Nuclear Energy Agency, and updates and expands the thermodynamic data on inorganic compounds and complexes of uranium, neptunium, plutonium, americium and technetium contained in the previous volumes of the series. A review team, composed of seven internationally recognized experts, has critically reviewed during five years all the scientific literature containing chemical thermodynamic information for the above mentioned systems that has appeared since the publication of the earlier volumes. The results of this critical review carried out following the Guidelines of the OECD NEA Thermochemical Database Project have been documented in the present volume, which contains new tables of selected values for formation and reaction thermodynamical properties and an extensive bibliography.

Uranium Enrichment and Nuclear Weapon Proliferation


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.




Ion Exchange Technology


Book Description




Application of Ion Exchange Processes for the Treatment of Radioactive Waste and Management of Spent Ion Exchangers


Book Description

Ion exchange is one of the most common and effective treatment methods for liquid radioactive waste. This book reviews the current literature on the subject and reports on the existing state of the art of the application of ion exchange processes for liquid radioactive waste treatments and of the management of spent ion exchange media.




Ion Exchange and Solvent Extraction


Book Description

The growth in the world's nuclear industry, motivated by peaking world oil supplies, concerns about the greenhouse effect, and domestic needs for energy independence, has resulted in a heightened focus on the need for next-generation nuclear fuel-cycle technologies. Ion Exchange and Solvent Extraction: A Series of Advances, Volume 19 provides a com




Rare Metal Extraction by Chemical Engineering Techniques


Book Description

Rare Metal Extraction by Chemical Engineering Techniques describes the use of chemical engineering techniques in the extraction and purification of rare metals such as uranium, thorium, and zirconium as well as hafnium, titanium, beryllium, and vanadium. The various chemical extraction stages from ore to metal are discussed. Comprised of nine chapters, this book begins with an examination of ore breakdown processes including dilute acid leaching and the breakdown of concentrated acids, alkalis, and fluorides as well as chlorination. The reader is then introduced to ion-exchange purification; solvent extraction; and dryway conversion processes. Subsequent chapters focus on metal production by high-temperature reduction techniques; molten salt electrolytic processes; and iodide decomposition processes. The final chapter includes a selection of complete flowsheets for the extraction and purification rare metals from ores. This monograph will be of value to metallurgists, chemical engineers, chemists, and others who are interested in the extraction of rare metals.







Ion Exchange in Analytical Chemistry


Book Description

Analytical Chemistry, Volume 38: Ion Exchange in Analytical Chemistry provides a broad survey of the important role that ion exchange can and should play in chemical analysis. This book focuses on the plate-equilibrium theory of chromatography, which is less difficult theoretically than the mass-transfer theory. Organized into 11 chapters, this volume begins with an overview of the earliest recorded application of ion exchange. This text then examines how high temperature affects ion-exchange resins. Other chapters consider the exchange of ions between a solid ion-exchanging material and a solution, which is a typically reversible reaction. This book describes as well the relatively simple separations and other applications of ion exchange to analytical chemistry. The final chapter deals with the interesting nature of the metal complexes formed within the exchanger and describe the use of ion-exchange distribution studies to determine the stability and nature of complexes existing in the solution. This book is a valuable resource for analytical chemists.




Ion Exchange Technology


Book Description

This book provides comprehensive coverage of developments in ion exchange areas which would continue to have major impacts in the general pursuit of pollution control and pollution prevention. Its nine chapters can be split into four different theme areas: trace contaminants removals; new materials; desalination and finally controlling gaseous pollutants. This would have value for practicing engineers, scientists and researchers who are pertaining to ion exchange technology. It would also server the needs of those trying to explore and identify new technologies in the areas of pollution control and pollution prevention.
