To develop new technologies for efficient operation and safe control of nuclear reactor systems, it is necessary to clarify quantitatively details of complicated thermal-hydraulic phenomena existing in energy transport and conversion processes. For example, understanding of reactor behavior, its consequences and impact in severe accidents, where the reactor core is largely damaged, is essential to evaluate reactor safety margins and to take measures for prevention of accident progression and for mitigation of accident consequences. In addition, in advanced nuclear reactors, to counter accidents, passive safety systems that rely only upon natural physical phenomena such as gravity, natural convection, etc. without electrical power supply and human intervention are required for reactor shutdown and the subsequent reactor cooling. In this research group, researches and developments relevant to safety designs and assessments are performed to enhance safety features of advanced light-water reactor, fast reactor and gas cooled reactor in the field of nuclear thermal-hydraulic and safety.
