Nuclear Disaster Prevention Systems Lab
Machine-translated · View original
A lab that studies the properties of nuclear fuels and new materials.

AboutAbout the lab
From nuclear fuel to thermoelectric materials: understanding the properties of materials
The Nuclear Disaster Prevention Systems Lab (Kurosaki Lab) studies the physical properties of nuclear fuels and reactor materials, develops new materials through materials informatics, and develops inexpensive, non-toxic, high-efficiency thermoelectric materials.
The lab also evaluates how the physical properties of nuclear fuel change when fission products accumulate in it, and works on developing accident tolerant fuel, which has drawn attention since the Fukushima Daiichi Nuclear Power Plant accident.
Key terms
- Fission products
- Other elements produced when nuclear fuel undergoes fission
- Accident tolerant fuel
- Nuclear fuel designed so that it is less likely to fail even if an accident occurs
- Thermoelectric material
- A material that generates electricity directly from a temperature difference
- Materials informatics
- A method of searching for new materials using large amounts of materials data and machine learning
ResearchResearch themes
The lab studies the physical properties of nuclear fuels and reactor materials, materials informatics, and thermoelectric materials.
*Illustrative imageFission Products and the Properties of Nuclear Fuel
The lab makes simulated fuels by adding various fission products to uranium dioxide, and evaluates how the accumulation of fission products changes the thermal conductivity and hardness of nuclear fuel.
*Illustrative imageNew Accident Tolerant Fuel
As candidates for accident tolerant fuel, which has drawn attention since the Fukushima Daiichi Nuclear Power Plant accident, the lab produces uranium silicides of various compositions and evaluates their physical properties.
*Illustrative imageMaterials Informatics
Using machine learning on large-scale materials data, the lab develops new nuclear fuel materials and thermoelectric materials.
*Illustrative imageInexpensive, Non-Toxic Thermoelectric Materials
Aiming at waste heat recovery and at technology that generates power over long periods from small temperature differences, the lab develops new thermoelectric materials based mainly on silicon.
