Book excerpt: Azimuthal propagation of disturbances in a large aunular reactor is investigated by studying the equalization of neutron bursts in a ring or simply- periodic reactor. One-velocity diffusion theory is employed to obtain convenient expressions for the time required for approximate equalization of neutron density around the ring. (auth).
Download or read book Fast Pulsed and Burst Reactors written by E. P. Shabalin and published by Elsevier. This book was released on 2013-09-11 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fast Pulsed and Burst Reactors: A Comprehensive Account of the Physics of both Single Burst and Repetitively Pulsed Reactors discusses the physical principles involved in the operation of fast burst and periodic pulsed reactors. The text first covers the concerns in fast burst reactors, such as the kinetics and the effects of thermal shock. Next, the book deals with periodic burst reactions, which include the neutronics theory, reactivity modulation, and fluctuations. The text also talks about the principles and problems of control and safety of periodic pulsed reactors. The book will be of great use to individuals involved in the operation of nuclear power plant, such as nuclear engineers. The text will also benefit scientists involved in nuclear research.

Book excerpt: Some calculations have been made to estimate the characteristics of a neutron-burst type fast reactor similar to Godiva but made up of relatively small component parts--the so-called "layered assembly." One spherical and three cylindrical assemblies have been considered. Critical masses, assuming 5% voids, range from 58 to 65 kg of 93.4% enriched U/sup 235/. For a reactivity addition of 0.33 dollars above prompt criticals bursts between 2 x 10/sup 17/ and 6.7 x 10/ sup 17/ fissions were computed with accompanying temperature rises varying from 514 to 1600 deg C. The burst width at half-maximum was about 12 microseconds. To obtain an idea of the possibilities of stress reduction which might be achieved by layerings an assembly made of small rings was considered. While the critical masses obtained here are believed to be fairly accurates the predictions concerning mechanical energy generated, total fissions, and burst width may be subject to sizeable error due to the many simplitications required to allow hand computations. Neverthelesss considerable improvement in safety and burst-size is indicated by the use of a "layered assembly" instead of an assembly composed of relatively thick parts. (auth).

Download or read book Neutron Scattering in Earth Sciences written by Hans Rudolf Wenk and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 63 of Reviews in Mineralogy and Geochemistry provides an introduction for those not yet familiar with neutrons by describing basic features of neutrons and their interaction with matter as well illustrating important applications. The volume is divided into 17 Chapters. The first two chapters introduce properties of neutrons and neutron facilities, setting the stage for applications. Some applications rely on single crystals (Chapter 3) but mostly powders (Chapters 4-5) and bulk polycrystals (Chapters 15-16) are analyzed, at ambient conditions as well as low and high temperature and high pressure (Chapters 7-9). Characterization of magnetic structures remains a core application of neutron scattering (Chapter 6). The analysis of neutron data is not trivial and crystallographic methods have been modified to take account of the complexities, such as the Rietveld technique (Chapter 4) and the pair distribution function (Chapter 11). Information is not only obtained about solids but about liquids, melts and aqueous solutions as well (Chapters 11-13). In fact this field, approached with inelastic scattering (Chapter 10) and small angle scattering (Chapter 13) is opening unprecedented opportunities for earth sciences. Small angle scattering also contributes information about microstructures (Chapter 14). Neutron diffraction has become a favorite method to quantify residual stresses in deformed materials (Chapter 16) as well as preferred orientation patterns (Chapter 15). The volume concludes with a short introduction into neutron tomography and radiography that may well emerge as a principal application of neutron scattering in the future (Chapter 17).

Download or read book Transmission Electron Microscopy and Diffractometry of Materials written by Brent Fultz and published by Springer Science & Business Media. This book was released on 2012-10-14 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains concepts of transmission electron microscopy (TEM) and x-ray diffractometry (XRD) that are important for the characterization of materials. The fourth edition adds important new techniques of TEM such as electron tomography, nanobeam diffraction, and geometric phase analysis. A new chapter on neutron scattering completes the trio of x-ray, electron and neutron diffraction. All chapters were updated and revised for clarity. The book explains the fundamentals of how waves and wavefunctions interact with atoms in solids, and the similarities and differences of using x-rays, electrons, or neutrons for diffraction measurements. Diffraction effects of crystalline order, defects, and disorder in materials are explained in detail. Both practical and theoretical issues are covered. The book can be used in an introductory-level or advanced-level course, since sections are identified by difficulty. Each chapter includes a set of problems to illustrate principles, and the extensive Appendix includes laboratory exercises.
