CNL investigates alloy with potential reactor applications
A research team led by Canadian Nuclear Laboratories is studying a type of high-entropy alloy (HEA) that seems to withstand a cascade-involved irradiation environment at elevated temperatures better than stainless steel exposed to similar conditions. In a paper published in the Journal of Nuclear Materials, the researchers describe an HEA made of chromium, iron, manganese, and nickel (CrFeMnNi) that has the potential to improve the safety and functionality of nuclear reactors, as well as of spacecraft.
