AboutAbout the lab
Uncovering the mechanisms of heat and flow through experiments and computation
The Furuya Lab conducts research that clarifies the mechanisms of heat and flow through both experiments and simulations.
It also incorporates new methods such as machine learning to deepen its understanding of these phenomena.
Using 3D printing, microfabrication technologies, and instrumental analysis, the lab also takes on catalyst technologies, which add chemical reactions to heat and flow, as well as materials informatics.
The lab's research centers on themes related to the safety of nuclear power plants and fusion reactors.
Key terms
- Thermal-hydraulic analysis
- A method of investigating how heat is transferred and how fluids move, using computation
- Materials informatics
- A research field that uses data science methods to develop new materials efficiently
- PIV (particle image velocimetry)
- An experimental technique in which particles are added to a flow of water or air and the flow velocity is measured from images

ResearchResearch themes
The Furuya Lab studies heat and flow phenomena that occur in nuclear power plants and fusion reactors, using both experiments and simulations. It also works on developing technologies that lead to improved safety.
*Illustrative imageEvaluating thermal effects in fusion reactors
For a fusion power demonstration reactor, the lab models changes in temperature and pressure in the event of a coolant leak or loss of power using thermal-hydraulic analysis with the TRACE code, and evaluates the effects on heat.
*Illustrative imageEnvironmental sensing with optical fibers
The lab develops technologies that use optical fiber sensors to measure the distribution of temperature, radiation dose, and fluid velocity in the harsh environments of nuclear and fusion plants.
*Illustrative imageThermal stratification in spent fuel pools
This research uses experiments employing particle image velocimetry (PIV) and other methods, together with analysis, to clarify thermal stratification, the phenomenon in which water temperature separates into layers when the cooling function of a spent fuel pool is lost.
*Illustrative imageSuppressing evaporation of spent fuel pool water
The lab devises methods to suppress the evaporation of cooling water in spent fuel pools during a loss of power, and verifies them through experiments.
