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.

In this paper some results of a study on the compatibility of SiC/SiC fiber ceramic composite with Li2O in fusion-relevant conditions are presented. The compatibility experiments were carried out at 800°C in flowing helium (0.1 L/min) containing 0.1% hydrogen. In these conditions, specimens of composite were kept in contact with Li2O under a static pressure of 20000 Pa for 2232 h in a chamber made of Inconel 600. Both as-received and exposed SiC/SiC specimens have been characterized. The results obtained demonstrate that SiC/SiC ceramic composite is chemically corroded only on the surface in these conditions and that its main physicochemical characteristics are not appreciably affected.
