Professor / Kazuyuki TAKASE
Dr. Takase has been assigned by the Japan Atomic Energy Agency, and has been studying complex heat and fluid phenomena in nuclear power plants. It is a very caring and friendly teacher who can give you accurate advice whenever a student gets stuck in research.

Research Content

Our laboratory mainly conducts the following research in the field of heat and fluidity.
・Numerical analysis on gas-liquid two-phase flow behavior in core subchannel
We are conducting a numerical analysis on the behavior of bubbles in a light water reactor.
Verification of bubble behavior is extremely important for improving LWR safety.
・Research on behavior and concentration reduction of hydrogen generated in long-term storage container for radioactive waste
Hydrogen becomes a flammable gas when mixed with air at 4% or more. The behavior and reduction of hydrogen concentration in the vessel when using hydrogen recombination catalyst are evaluated both experimentally and numerically.

A Day in the Lab

Our laboratory has no core time and can conduct research at its own discretion. Once a week, a seminar hold progress reports and study sessions related to the research content. The background of students belonging to the lab varies from mechanical, electrical and chemical, so don't worry if you don't have any knowledge about nuclear power! If you are interested, please come to our laboratory and ask. Also, there are international students in the lab, so you have the opportunity to use English and improve your language skills.
