Official Title Professor
Affiliation Department of Nuclear Safety Engineering
Profile I have been involved in experimental research and numerical simulation for reactor safety engineering and severe accident evaluation based on the knowledge of thermal hydraulics.
Since 2002, I have been concerned with research and development of accelerator-driven subcritical reactors (ADSs) at Karlsruhe Institute of Technology (KIT) by using safety evaluation code SIMMER-III.
Since 2006, I have been leading the safety evaluation and licensing analysis of fast breeder reactors at Japan Atomic Energy Agency (JAEA).
Since 2017, I have been engaged in research and education related to nuclear safety engineering at the Department of Nuclear Safety Engineering, Tokyo City University.
