Page 6 - Dynamics and Control of Nuclear Reactors

Preface

The transient behavior of nuclear power reactors depends on the inherent character-
istics of the system and the performance of control systems. These issues must be
analyzed to predict and understand the performance of a power reactor. This book
deals with the methods needed for this analysis.
The book is designed to be useful as an introductory text and as a text for
advanced study. Customizing the presentation by an instructor to match the level
of the student is accomplished by selection of appropriate chapters and appendices.
Analysis of reactor dynamics is presented both in the time domain and in the fre-
quency domain. The basics of frequency response analysis of linear systems are
described in the appendix.
It is assumed that the student has introductory knowledge of nuclear reactor phys-
ics. Appendices that deal with basic material may be used as needed for introduction
or review. Advanced students with appropriate prior knowledge can omit these
Appendices. The authors strongly recommend that the student review the Appendi-
ces; these are an important supplement to the book chapters.
Appendices that deal with advanced topics are suitable for advanced readers.
These appendices are probably too detailed for use by introductory readers. Placing
advanced material in appendices avoids inclusion of topics in the body of the book
that would be confusing to introductory readers.
The book contains numerous problems and exercises. Some are designed to
familiarize readers with application of techniques presented in the book. They are
appropriate for readers of all levels. Some exercises and problems are more involved
and are intended for advanced readers. These include assignments that require
reporting on topics covered in the literature.
It is hoped that the approach used in this book will provide instructors with the
flexibility needed to adapt to the prior knowledge of the students in his/her class.
One might ask why a new book on nuclear power is needed. Many people think
that nuclear power is unsafe, too expensive or unnecessary because of other
environment-friendly options for producing power, mainly solar or wind power.
The reader deserves to know the opinion of the authors on the need for nuclear power.
It is as follows:

Ø Wind and solar power are intermittent due to dependence on nature. The authors
support the use of wind and solar to its maximum capability.
Ø Even though locally-produced power will increase, there will always be a need
for large power plants.
Ø Power generation from plants that burn fossil fuels will decrease because of
pollution and climate change concerns.
Ø Nuclear power plants are safe because of lessons learned, emphasis on safety in
reactor design and operation, and a strong safety culture. But, operators must
fully understand the reactor and its operational features in order to avoid mistakes.
