Preface

This text develops the theory of nuclear reactors from the fundamentals of fission to the operating characteristics of modern reactors. It is aimed at a senior undergraduate or first year graduate student level. It is designed as a two-semester text with the first half emphasizing reactor criticality analysis and all of the physics that goes into modern calculations. It will start with simplified one-group diffusion theory models and extend into sophisticated multigroup transport theory models. Each chapter will have at least one example covering the issues discussed. Desktop calculations will be discussed and demonstrated in examples. A small one-dimensional computer code will be provided to demonstrate the models discussed. Resonance theory, thermal scattering, and heterogeneous effects will be discussed and characterized. Detailed data sets will be provided that will allow two-, three-, and four-group desktop calculations. Additional multigroup data sets will be provided with the computer disk. The second half of the book will deal with the two main topics of interest to operating reactors—reactor kinetics/dynamics and in-core fuel management. Based on the fundamental physics discus
