Energy Creation Materials Science Lab
Machine-translated · View original
A lab that studies the treatment and disposal of nuclear fuel and radioactive waste.

AboutAbout the lab
The keywords are recycling and safety.
The Energy Creation Materials Science Lab, with the broad aim of harmonizing future energy development with the Earth's resources, studies next-generation nuclear fuel and the treatment and disposal of radioactive waste.
The lab's website regards spent fuel not as "troublesome" waste but as a treasure trove, and puts forward recycling and safety as its keywords.
Its research is divided into nuclear fuels such as ceramic fuels, solidified waste forms such as high-level waste glass, and the behavior of radionuclides in montmorillonite and granite.
On the lab's website, it is also referred to as the "Inagaki Lab."
Key terms
- Vitrified waste form
- Radioactive waste solidified in glass. How it dissolves over long periods is the subject of evaluation
- Bentonite
- A type of clay. The lab studies how elements diffuse in it
- First-principles calculation
- A method that predicts the properties of materials by calculation from the fundamental laws of physics, without relying on experimental data
- Molecular dynamics
- A method that tracks the motion of atoms and molecules on a computer to predict the properties of materials
ResearchResearch themes
Aiming to harmonize future energy development with the Earth's resources, the lab studies next-generation nuclear fuel and the treatment and disposal of radioactive waste. Its topics include evaluating the physical properties of nuclear fuel, the movement of elements in solidified waste forms and clay, and waste management using cement and minerals.
*Illustrative imageEvaluating the Physical Properties of Next-Generation Nuclear Fuel
The lab investigates physical properties under extreme conditions, such as the melting point of nuclear fuel and the viscosity of molten fuel, and also develops measurement methods. It pursues evaluation using lasers, prediction by first-principles calculations and molecular dynamics, and the evaluation of nitride fuels, alloy fuels, and fuel damaged in accidents.
*Illustrative imageTreatment and Disposal of Radioactive Waste
To dispose of radioactive waste from nuclear facilities stably, the lab evaluates the long-term safety of disposal systems by combining physical chemistry, geology, and engineering. It studies how vitrified high-level waste dissolves and how elements diffuse in bentonite.
*Illustrative imageWaste Management Using Cement and Minerals
This research uses the mechanisms of cement and minerals to manage waste from a range of industries, from the petroleum industry to the nuclear industry. The lab also works on capturing CO2 from exhaust gas.
