This task is, however, quite challenging because of several complex dynamic phenomena existing in a reactor. Quite often, the models developed would be of prohibitively large order, non-linear and of complex structure not readily amenable for control studies. Moreover, the existence of simultaneously occurring dynamic variations at different speeds makes the mathematical model susceptible to numerical ill-conditioning, inhibiting direct application of standard control techniques. This monograph introduces a technique for mathematical modeling of large nuclear reactors in the framework of multi-point kinetics, to obtain a comparatively smaller order model in standard state space form thus overcoming these difficulties. It further brings in innovative methods for controller design for systems exhibiting multi-time-scale property, with emphasis on three-time-scale systems.

The book, which is a result of the lectures given at the University of Michigan, is composed of seven chapters. The opening chapter of the book describes various physical phenomena influencing the temporal behavior of neutrons to provide insights into the physics of reactor dynamics and the interrelationships between various diverse phenomena. The text then presents a set of equations, called point kinetic equation, which describes the time behavior of the total power generated in the medium.

At least in the new sense. Let's say Plato, Rousseau.

The book also provides a short discussion on Gyftopoulos modification and Becker’s formulation. The next chapters explore the exact methods for solving the feedback-free point kinetic equations for a number of reactivity insertions and the validity of the various approximate methods of solution.

The book also examines the derivation of models for a certain reactor type and briefly discusses the validity of these models in certain cases against experimental data. A chapter focuses on a concise presentation of the stability theory of linear systems with feedback. Lastly, the concepts of stability in nonlinear reactor systems and the criteria for asymptotic stability in the large as well as in a finite domain of initial disturbances are covered in the concluding chapter.

The text is an ideal source for nuclear engineers and for those who have adequate background in reactor physics and operational and applied mathematics.

Author by: Jeffery Lewins Language: en Publisher by: Elsevier Format Available: PDF, ePub, Mobi Total Read: 55 Total Download: 755 File Size: 50,5 Mb Description: Nuclear Reactor Kinetics and Control highlights the application of classical control methods in the frequency space to the dynamic processes of a nuclear reactor.

This book contains nine chapters and begins with an introduction to some important mathematical theories related to nuclear engineering, such as the Laplace and Fourier transforms, linear system stability, and the probability theory. The succeeding chapters deal with the frequency space of classical linear design. A chapter describes a stochastic model for the “lumped reactor and presents equations that measure the departure from the mean, as well as representative experiments or applications of the theory to neutron detection.

The discussion then shifts to the aspects of reliability and its consequences for safety of nuclear reactors and some techniques for nonlinear studies centered on the use of the state space and its equations in the time domain. The final chapter introduces the modern electric analogue computer and derives the patching or programming rules that can be use to find solutions to problems of interest using the analogous behavior of electric circuits. This chapter also provide examples of intrinsic interest in nuclear engineering showing the programming involved and typical results, including the slower transients of xenon poisoning and fuel burn-up. This book is intended for nuclear engineers, physicists, applied mathematicians, and nuclear engineering undergraduate and postgraduate students. Author by: F Farmer Language: en Publisher by: Elsevier Format Available: PDF, ePub, Mobi Total Read: 65 Total Download: 503 File Size: 46,7 Mb Description: Nuclear Reactor Safety aims to put the nuclear hazard in perspective by providing an objective overall technical review of the field. It focuses on reactor accidents and their consequences.

The technical arguments will be concerned broadly with reactor accident conditions and will deal with both the arrangements necessary to prevent any dangerous diversion from normal operation and to ameliorate the consequences if such a diversion should occur. The book is organized into three parts. Part I describes the nature of fission products and the hazards to man and his environment resulting from the uncontrolled release of fission products in accident conditions. Part II discusses a quantitative approach to reactor safety assessment and the quantification of vessel integrity.

Part III deals with the basic principles of analysis and assessment of reactor safety, and then considers the specific safety problems of thermal and fast reactors in detail. This book is intended for two types of readers. First are technicians, those engaged in nuclear engineering: designers, constructors, and operators of nuclear stations, as well as those who would make a career in nuclear safety. Second are those (not necessarily scientists) who are tasked with making decisions in the field of energy use and allocation, or are concerned with environmental matters. Author by: Weston M. Stacey Language: en Publisher by: Elsevier Format Available: PDF, ePub, Mobi Total Read: 46 Total Download: 943 File Size: 48,9 Mb Description: Nuclear Science and Technology, Volume 10: Variational Methods in Nuclear Reactor Physics presents the mathematical methods of a variational origin that are useful in obtaining approximate solutions to science and engineering problems.

This book is composed of five chapters and begins with a discussion on the variation principles for physical systems described by both inhomogeneous and homogeneous equations to develop a generalized perturbation theory. Chapter 2 deals with the applications of variational estimates and generalized perturbation theory to neutron transport problems. Chapter 3 covers the variation principles of the Lagrangian form that are constructed for a general, linear- time-dependent process and for the specific case of the P1 neutron kinetics equations. Chapter 4 presents the general procedure for the variational derivation of synthesis approximations and their applications to problems in reactor physics.

This chapter also examines the relationship of the spatial synthesis and finite-element method and a hybrid method that combines features of both methods. Chapter 5 describes the relationship of variation theory with the Hamilton-Jacobi theory and with the optimization theories of the maximum principle and dynamic programming. Nuclear physicists and researchers will find this text invaluable.

This eight-chapter book emphasizes the determination of the system frequency response using nonsinusoidal input perturbations, which are useful since normal power reactor hardware can be used. This text deals first with the mathematical aspects of frequency response testing, with a particular emphasis on numerical Fourier transformations using analog or digital equipment. The subsequent chapters examine the important signals for use in frequency responses tests and the analysis of these signals using analog and digital computing equipment. The discussion then shifts to the frequency response functions that describe nuclear reactor dynamics.

This topic is followed by a presentation of techniques for extracting useful information from test results. A chapter highlights the most common control-rod drive mechanisms to assess their suitability for dynamics testing. The concluding chapter provides a brief summary of significant experiences with dynamics tests in nuclear reactors. Scientists, researchers, and workers in the field of nuclear reactors and related subjects will find this book invaluable.

Introduces Novel Applications for Solving Neutron Transport Equations While deemed nonessential in the past, fractional calculus is now gaining momentum in the science and engineering community. Various disciplines have discovered that realistic models of physical phenomenon can be achieved with fractional calculus and are using them in numerous ways. Since fractional calculus represents a reactor more closely than classical integer order calculus, Fractional Calculus with Applications for Nuclear Reactor Dynamics focuses on the application of fractional calculus to describe the physical behavior of nuclear reactors. It applies fractional calculus to incorporate the mathematical methods used to analyze the diffusion theory model of neutron transport and explains the role of neutron transport in reactor theory. The author discusses fractional calculus and the numerical solution for fractional neutron point kinetic equation (FNPKE), introduces the technique for efficient and accurate numerical computation for FNPKE with different values of reactivity, and analyzes the fractional neutron point kinetic (FNPK) model for the dynamic behavior of neutron motion. The book begins with an overview of nuclear reactors, explains how nuclear energy is extracted from reactors, and explores the behavior of neutron density using reactivity functions.
