Mechanical and corrosion studies of nuclear materials at elevated temperatures and in molten salts

Small Modular Reactors (SMRs) are being developed to tackle the global need for safe, clean, economical energy. In contrast to traditional CANDU reactors, SMRs require materials to operate in more severe conditions - at higher temperatures and pressures and in more corrosive environments. Unfortunately, data about material behaviour in these conditions are severely lacking. This is a major barrier to ever licensing SMRs for deployment. In this project, we will produce critical data on the degradation mechanisms of nuclear materials in SMRs. Our team will examine typical Fe- and Ni-based nuclear materials at elevated temperatures up to 1,000°C and in molten fluoride (F) and chloride (Cl) salts. We will carry out corrosion, creep rupture, stress corrosion cracking, and corrosion fatigue tests and provide qualified data to support regulatory decision-making and oversight.
