Natural circulation systems in nuclear reactors: advantages and challenges

Abstract

Abstract Following the Fukushima disaster in Japan in March 2011, a number of questions and doubts about the safety of nuclear reactors have been raised globally and many nations have begun revising and improving the nuclear installations. Natural circulation plays a major role in nuclear accident. This significance of the natural circulation-based systems led us to study the natural circulation phenomena for better understanding and in order to ensure the safety and efficiency of natural circulation systems. This review focuses on the advantages and challenges of natural circulation systems.
