Download or read book Air and Concrete Scattering of Neutrons Monte Carlo Calculations written by M. B. Wells and published by . This book was released on 1958 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents results from Monte Carlo calculations of the angular distribution of neutrons scattered from air and concrete. The Monte Carlo method was used to evaluate the integrals that represent the contribution to the total scattered flux from the first five orders of scattering. The scattered neutron flux at various separation distances was computed for a 3.25 Mev point monodirectional source located at a height of 12.5 feet above the surface of a concrete slab. Differential scattering cross sections based on a complex square well model and differential scattering cross sections assuming isotropic scattering in the center of mass system were used in the Monte Carlo calculations. The method used in computing the variance of the scattered flux is outlined. The standard deviation computed was found to be generally not more than 10% of the scattered flux. This report supplements the information presented in Convair-Fort Worth report FZK-9-120A.

Available in PDF, EPUB and Kindle. Book excerpt: With this book we try to reach several more-or-less unattainable goals namely: To compromise in a single book all the most important achievements of Monte Carlo calculations for solving neutron and photon transport problems. To present a book which discusses the same topics in the three levels known from the literature and gives us useful information for both beginners and experienced readers. It lists both well-established old techniques and also newest findings.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental data were obtained on neutron and gamma-ray attenuation and on neutron activation for representative field materials and on air scattering of radiation. Field materials tested were dry sand, wet sand, clay, limestone, water, a soil mixture, and pine wood. Results of the experiments showed the following: of the materials tested a given thickness afforded more fast-neutron attenuation than gamma-ray attenuation. Secondary-gamma-ray production in expedient materials is an important consideration dependent on the water (hydrogen) content in the material.

Download or read book Monte Carlo Calculations of the Penetration of Normally Incident Neutron Beams Through Concrete written by F. H. Clark and published by . This book was released on 1967 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 05R Monte Carlo code (See ORNL-3622, NASA N65-17892) was adapted to calculate fast-neutron doses within and outside of concrete slab shields. Such calculations were performed for a variety of shield thicknesses (0 to 180 cm) and for various monoenergetic sources from 0.7 to 14 MeV. The concrete chosen is ordinary concrete with approximately 6% water content. Results are plotted as tissue kerma versus penetration distance for each source energy. The source is in each case a broad normally incident beam. (Author).

Download or read book Monte Carlo Principles and Neutron Transport Problems written by Jerome Spanier and published by Courier Corporation. This book was released on 2008-01-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-part treatment introduces the general principles of the Monte Carlo method within a unified mathematical point of view, applying them to problems in neutron transport. It describes several efficiency-enhancing approaches, including the method of superposition and simulation of the adjoint equation based on reciprocity. The first half of the book presents an exposition of the fundamentals of Monte Carlo methods, examining discrete and continuous random walk processes and standard variance reduction techniques. The second half of the text focuses directly on the methods of superposition and reciprocity, illustrating their applications to specific neutron transport problems. Topics include the computation of thermal neutron fluxes and the superposition principle in resonance escape computations.
