Download or read book Extrapolated Experimental Critical Parameters of Unreflected and Steel reflected Massive Enriched Uranium Metal Spherical and Hemispherical Assemblies written by and published by . This book was released on 1997 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixty-nine critical configurations of up to 186 kg of uranium are reported from very early experiments (1960s) performed at the Rocky Flats Critical Mass Laboratory near Denver, Colorado. Enriched (93%) uranium metal spherical and hemispherical configurations were studied. All were thick-walled shells except for two solid hemispheres. Experiments were essentially unreflected; or they included central and/or external regions of mild steel. No liquids were involved. Critical parameters are derived from extrapolations beyond subcritical data. Extrapolations, rather than more precise interpolations between slightly supercritical and slightly subcritical configurations, were necessary because experiments involved manually assembled configurations. Many extrapolations were quite long; but the general lack of curvature in the subcritical region lends credibility to their validity. In addition to delayed critical parameters, a procedure is offered which might permit the determination of prompt critical parameters as well for the same cases. This conjectured procedure is not based on any strong physical arguments.

Download or read book Neutron Fluctuations written by Imre Pazsit and published by Elsevier. This book was released on 2007-10-05 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transport of neutrons in a multiplying system is an area of branching processes with a clear formalism. Neutron Fluctuations presents an account of the mathematical tools used in describing branching processes, which are then used to derive a large number of properties of the neutron distribution in multiplying systems with or without an external source. In the second part of the book, the theory is applied to the description of the neutron fluctuations in nuclear reactor cores as well as in small samples of fissile material. The question of how to extract information about the system under study is discussed. In particular the measurement of the reactivity of subcritical cores, driven with various Poisson and non-Poisson (pulsed) sources, and the identification of fissile material samples, is illustrated. The book gives pragmatic information for those planning and executing and evaluating experiments on such systems. - Gives a complete treatise of the mathematics of branching particle processes, and in particular neutron fluctuations, in a self-contained manner - The first monograph containing the theory and application of neutron fluctuations in low power ADS (spallation and pulsed sources) - Suitable as a tutorial and handbook/reference book for scientists and graduate students - One of the authors is the founder of the mathematical theory of neutron fluctuations in zero power systems

Download or read book Neutron Physics written by Karl-Heinrich Beckurts and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based upon a series of lectures I have occasionally given at the University of Gottingen since 1951. They were meant to introduce the students of experimental physics to the work in a neutron physics laboratory dealing with the problem of measuring neutron flux, diffusion length, Fermi age, effective neutron temperature, absorption cross sections and similar problems. Moreover, these lectures were intended to prepare the students for a subsequent lecture covering the physics of nuclear reactors. The original character of this series of lectures has been retained in the book. It is intended for use by students as well as anyone desiring to work on neutron physics measurements. The first half mainly covers the theory of neutron fields, i. e. essentially diffusion and slowing down theory. The second half is largely concerned with measurements in neutron fields. The appendix contains information and data which, in our experience, are frequently required in a neutron laboratory. The field of nuclear physics proper is briefly touched upon in the first two chapters, but only to the extent necessary for the understanding of the following chapters. The multitude of applications of neutron radiation has not been covered. The conclusion of this manuscript coincided with the end of my long period of activity with the Max-Planck-Institut fur Physik at Gottingen. To Professor HEISENBERG lowe thanks for his advice and suggestions for many of the subjects treated here.
Download or read book Investigating Developmentalism written by Dev Nath Pathak and published by Springer. This book was released on 2019-06-18 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compiling various strands of the dis/enchantment with development discourse in contemporary South Asia, with specific focus on the cases from India, this edited book brings together anthropologists, sociologists, economists, and historians to refresh the understanding of development. It introduces ways of thinking “otherwise” about development discourse and what the contributors term “developmentalism”—the social enchantment with development. The cultural discourse of development in contemporary South Asia manifests not only in the official programs of state agencies, but in cinema, television, and mass media. Dear to various stakeholders—from government leaders and manufacturers to consumers and the electorate—is the axiom of a “development(al) society.” Organized to bridge familiar understandings of development with radical ways of thinking through developmentalism, this book holds value for those engaged in the anthropology and sociology of development, development studies, South Asian studies, as well as for development professionals working for state and non-governmental organizations.
