Handbook on Thermal Hydraulics of Water-Cooled Nuclear Reactors, Volume 1, Foundations and Principles includes all new chapters which delve deeper into the topic, adding context and practical examples to help readers apply learnings to their own setting. Topics covered include experimental thermal-hydraulics and instrumentation, numerics, scaling and containment in thermal-hydraulics, as well as a title dedicated to good practices in verification and validation. This book will be a valuable reference for graduate and undergraduate students of nuclear or thermal engineering, as well as researchers in nuclear thermal-hydraulics and reactor technology, engineers working in simulation and modeling of nuclear reactors, and more.In addition, nuclear operators, code developers and safety engineers will also benefit from the practical guidance provided.- Presents a comprehensive analysis on the connection between nuclear power and thermal hydraulics- Includes end-of-chapter questions, quizzes and exercises to confirm understanding and provides solutions in an appendix- Covers applicable nuclear reactor safety considerations and design technology throughout
