Single-phase, Two-phase and Supercritical Natural Circulation Systems brings together the latest research and knowledge into one unique reference and provides the reader with a deep understanding of natural circulation systems. This book will equip the reader with an understanding of how to detect unstable loops to ensure plant safety and reliability, calculate heat transport capabilities, and design effective natural circulation loops, stability maps and parallel channel systems.

Dr. Vijayan brings to this work a wealth of varied experience and knowledge, and adopts a very methodical, applied approach. Each chapter begins with an introduction of the circulation system, before discussing each element in detail and analyzing their effect on the performance of the system. He presents the use of thermosyphon heat transport devices in nuclear and other industrial plants, a common information need for students and researchers alike, and provides detailed discussion on how to calculate the effects of changing specific elements of a system. This book is invaluable for engineers, designers, operators and consultants in nuclear, mechanical, electrical and chemical disciplines.



  • Presents single-phase, two-phase and supercritical natural circulation systems together in one resource to fill an existing knowledge gap, aimed at the nuclear, mechanical and chemical engineering disciples
  • Guides the reader through relevant processes such as designing, analyzing and generating stability maps and natural circulation loops, calculating heat transport capabilities and maintaining natural circulation system operations
  • Includes global case studies and examples to increase understanding, as well as important IAEA standards and procedures

Dr Pallippattu Krishnan Vijayan is currently working as a Raja Ramanna Fellow at the Bhabha Atomic Research Centre (BARC) and his research focuses on natural circulation based passive safety systems for advanced reactors. Dr Vijayan, a chemical engineer from the University of Calicut joined BARC after completing the training course in nuclear science engineering conducted by BARC. He received his PhD from the Department of Energy Systems Engineering, IIT Bombay in 1989. A Distinguished Scientist, Dr Vijayan served at BARC in various positions such as group leader, head, thermal hydraulics section, head reactor engineering division and Director, Reactor Design and Development Group. He has worked nearly four decades in the field of thermal hydraulics of nuclear reactors and his specific field of expertise is natural circulation based passive safety systems. He played a key role in the thermal hydraulic design of thorium based Advanced Heavy Water Reactor (AHWR) and established large scale integral test facilities for its thermal hydraulic design validation. He participated in several International Atomic Energy Agency (IAEA) coordinated research projects and bilateral research projects like Indo-Italian, Indo-German, Indo-UK, Indo-Korea and AERB-US NRC. He was one of the experts invited by IAEA to formulate a training course on ‘Natural circulation phenomena and passive safety systems for advanced water cooled reactors’ and is a lecturer for this IAEA training course since 2004.
