Energy Effects in Modeling Neutron Diffusion: Two-Group Models,curate eigenvalue and accurate reaction rates. Since the cross sections vary wildly by multiple orders of magnitude over the energy range in a typical nuclear reactor, the major problem becomes one of determining accurate multi-group cross sections for the design problem under consideration.

Numerical Methods in Modeling Neutron Diffusion,tions to linear transport equation. FEMP code is a computer code written in FORTRAN 77, to approximate the Boltzmann transport equation in one-dimensional form using a spherical harmonic for the angular variable and a linear finite element for the spatial variable.

Thermal Spectra and Thermal Cross Sections,a reasonable first approximation in performing rudimentary reactor calculations. The main aspect of nuclear reactor analysis, as we have learned so far, is a multi-group diffusion theory. In previous chapters, we developed the general form of multi-group diffusion equations and recommended a strateg

Perturbation Theory for Reactor Neutronics,e behavior of a reactor. On the other hand, for a uniform occurrence of perturbation throughout the entire reactor or a region of it, then, we use methods that we have so far discussed and presented in previous chapters, although we never encounter uniform perturbation in practice of reactor operati

Reactor Kinetics and Point Kinetics, to be of any practical application. The diffusion approximation, obtained by keeping only the PI terms of the spherical harmonic expansion in the angular variable of the directional flux, is frequently used in neutronic analysis. This chapter discusses reactor characteristics that change because of

Numerical Modeling for Time-Dependent Problems, raised during World War II in the United States by scientists involved in Manhattan Project and the US Atomic Bomb Program. In the past two decades, the Soviet Union, the United Kingdom, France, Germany, Japan, and India followed the United States in developing a nationalized plutonium-breeder reac
