The third edition of this popular book is updated to include a completely revised discussion of reactor technology, an improved discussion of the reactor physics, and a more detailed discussion of basic nuclear physics and models. bull; Introduces the basics of the shell model of the nucleus and a beginning discussion of quantum mechanics. Discusses both U.S. and non-U.S. reactor designs, as well as advanced reactors. Provides for a more detailed understanding of both reactor statics and kinetics. Includes updated information on reactor acidents and safety.

Preface to Third Edition This revision is derived from personal experiences in teaching introductory and advanced level nuclear engineering courses at the undergraduate level. In keeping with the original intent of John Lamarsh, every attempt is made to retain his style and approach to nuclear engineering education. Since the last edition, however, considerable changes have occurred in the industry. The changes include the development of advanced plant designs, the significant scale-back in plant construction, the extensive use of high speed computers, and the opening of the former Eastern Block countries and of the Soviet Union. From a pedagogical view, the World Wide Web allows access to many resources formerly only available in libraries. Attempts are made to include some of these resources in this edition. In an attempt to update the text to include these technologies and to make the text useful for the study of non-western design reactors, extensive changes are made to Chapter 4,Nuclear Reactors and Nuclear Power.The chapter is revised to include a discussion of Soviet-design reactors and technology. The use, projection, and cost of nuclear power worldwide is updated to the latest available information. In Chapter 11,Reactor Licensing and Safety,the Chernobyl accident is discussed along with the latest reactor safety study, NURG 1150. A section is also included that describes non-power nuclear accidents such, as Tokai-Mura. The basic material in Chapters 2-7 is updated to include newer references and to reflect the author's experience in teaching nuclear engineering. Throughout the text, the references are updated were possible to include more recent publications. In many topic areas, references to books that are dated and often out of print had to be retained, since there are no newer ones available. Since these books are usually available in college libraries, they should be available to most readers. Chapter 9 is retained in much its same form but is updated to include a more complete discussion of the SI system of units and of changes in philosophy that have occurred in radiation protection. Since many of these changes have yet to reach general usage, however, the older discussions are still included. As in the second edition, several errors were corrected and undoubtedly new ones introduced. Gremlins never sleep!
