Available in PDF, EPUB and Kindle. Book excerpt: This report describes a method for computation of neutron age to the indium resonance in arbitrary mixtures of nuclides. Ages of fission neutrons in a wide variety of modulators were calculated. The method is the Fourier transformed moments solution of the Boltzmann equation, evaluated with multigroup techniques. Initially, the evaluation was for 68 groups; however, the number of groups was systematically reduced until an eleven group set was selected as a reasonable compromise between accuracy and ease of computation. The program not only computes group ages, but also provides a slowing down spectrum of average group fluxes per unit lethargy versus lethargy. Combined with a cross section averaging subroutine, this code could provide all required fast constants for a few group reactor physics problem. The final code will handle any number of groups up to twenty. Input data for any one problem is minimal, the main portion of the input consists of a punched card cross section library. It is an economic, simple to execute, versatile code, which meets the engineering accuracy criteria initially postulated. (Author).

Book excerpt: This report describes a method for calculatingneutron age values for any homogeneous, nonmultiplying medium. The method accounts for the effects of both inelastic and anisotropic neutron scattering. In the derivation of the method, Fourier transform techniques are used to develop, from the multi-group diffusion model, two simple recursive formulas which generate group average neutron age. The group average neutron ages are then used to estimate the age as a continuous function of lethargy. The method is applied tocompute the age to indium resonance from a U-235 fission source in some sample moderators (Be, BeO, C, C12H10, and H2O). The quality of the results indicates that the method should provide good values of neutron age for use in reactordesign calculations. The prime advantage of the method is the ease with which the age calculations can be made. In many applications, hand calculations would be possible. (Author).

This book was released on 1979 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple relation is derived between the thick target yield of neutrons produced following (alpha, n) reactions in compounds or homogeneous mixtures and the yields in the separate constituents. It is necessary to assume that the Bragg law of additivity of stopping powers holds for the compound and to make the approximation that the stopping powers of all materials vary with energy in the same way apart from constant factors. The range of validity of the second hypothesis is examined in some detail. It is shown to be far superior to the approximation of a stopping power independent of energy. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Theory of Neutron Slowing Down in Nuclear Reactors focuses on one facet of nuclear reactor design: the slowing down (or moderation) of neutrons from the high energies with which they are born in fission to the energies at which they are ultimately absorbed. In conjunction with the study of neutron moderation, calculations of reactor criticality are presented. A mathematical description of the slowing-down process is given, with particular emphasis on the problems encountered in the design of thermal reactors. This volume is comprised of four chapters and begins by considering the problems of neutron moderation and their importance in all types of reactors. An asymptotic reactor model is described, and the calculation of the elastic scattering frequency is explained. Subsequent chapters focus on the process of slowing down in finite and infinite medium by analyzing capture by individual resonances; resonance integrals in heterogeneous systems; the slowing-down kernels; the spherical harmonics method; statistical methods; and small source theory. The final chapter presents numerical solutions of the Boltzmann equation and covers topics such as the multigroup approach, group constants, and solution of the multigroup equations. This book will be a useful resource for nuclear physicists and engineers.
