Available in PDF, EPUB and Kindle. Book excerpt: 35p. By use of a modified thermobalance and reactor as the primary experimental tool for sample preparation and evaluntion, a process was developed by which parent uranium feed materials of widely variable reactivity and composition may be converted to a uniformly reactive uranium dioxide. Although numerous methods have been devised for improving the gas-solid reactivity of uranium dioxide toward hydrogen fluoride, none has overcome completely the initial variability of the available materials. Oxygen enrichment of uranium dioxide by incomplete reduction or partial reoxidntion accompanied by intermediate cooling increased hydrofluorination reactivity by as much as 50 per cent. However, this intentional introduction of uranyl fluoride as an impurity in the uranium tetrafluoride product incurs a fluorine penalty'' in its final conversion to uranium hexafluoride. Furthermore, uranyl fluoride impurity levels of this order cannot be tolerated in uranium tetrafluoride intended for reduction to metal. Complete atmospheric reoxidntion following the initial reduction of uranium feed materials to uranium dioxide produced urano-uranic oxide from which a stoichiometric uranium dioxide possessing uniform and much improved reaction characteristics could be made. Gains made available by the process are pointed out and problems remaining to be solved are formulated. (auth).

Download or read book Radiation Biophysics written by Edward L. Alpen and published by Academic Press. This book was released on 1997-10-22 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly revised and updated edition of Radiation Biophysics provides an in-depth description of the physics and chemistry of radiation and its effects on biological systems. Coverage begins with fundamental concepts of the physics of radiation and radioactivity, then progresses through the chemistry and biology of the interaction of radiation with living systems. The Second Edition of this highly praised text includes major revisions which reflect the rapid advances in the field. New material covers recent developments in the fields of carcinogenesis, DNA repair, molecular genetics, and the molecular biology of oncogenes and tumor suppressor genes. The book also includes extensive discussion of the practical impact of radiation on everyday life. Covers the fundamentals of radiation physics in a manner that is understandable to students and professionals with a limited physics background Includes problem sets and exercises to aid both teachers and students Discusses radioactivity, internally deposited radionuclides, and dosimetry Analyzes the risks for occupational and non-occupational workers exposed to radiation sources

Download or read book Uranium Enrichment and Nuclear Weapon Proliferation written by Allan S. Krass and published by Routledge. This book was released on 2020-11-20 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
