Introduction of research fields

Nuclear Engineering

We engage in education and research related to reactor physics, reactor engineering, radiation, nuclear fuel, nuclear reactor material and other fields that serve as the basic and fundamental technology for nuclear power generation as well as decommissioning measures in the aim of improving the safety and economic efficiency of existing light water reactors and developing new reactors such as fast breeder reactors. In addition to the world’s most advanced research and education on nuclear power for the achievement of a low-carbon society, we are tackling the matters of medical use of radiation and nuclear disaster prevention engineering in the aim of achieving results that can contribute to the local society and research and development using facilities in Fukui Prefecture.
