Diffusion of Neutrons in a Heavy Elements Medium and Application to the Multigroup Diffusion Theory

Radiation Mechanics

Mechanics is the science of studying energy and forces, and their effects on matter. It involves mechanisms, kinematics, cross sections, and transport. Radiation mechanism describes how various types of radiation interact with different targets (atoms and nuclei). The book addresses the above four aspects of radiation mechanics integrating these aspects of radiation behavior in a single treatise under the framework of "radiation mechanics". - Covers all aspects of radiation mechanics - Helps non-nuclear graduates readily familiarize themselves with radiation - Integrates and coordinates mechanisms, kinematics, cross sections and transport in one volume - End of each chapter problems to further assist students in understanding the underlying concepts - Use of computations and Internet resources included in the problems

The Theory of Neutron Slowing Down in Nuclear Reactors

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.
