Adrien Couet's research includes the study of materials degradation in extreme conditions with a focus on current and advanced nuclear reactors. Couet studies how materials, their environment, and the stresses with which they come into contact, tend to couple in ways that are less than fortuitous for the maintenance and safety of a nuclear power plant. At the MaDCoR (Materials Degradation under Corrosion and Radiation) laboratory, Couet and his research group investigate high-temperature corrosion and irradiation effects in materials as well as the design of these materials to better withstand these aggressive conditions. The MADCoR lab’s vision is to understand corrosion and irradiation effects from a fundamental perspective using first-principles as well as high-throughput methods to accelerate materials discovery and qualification for a more sustainable future. The group’s area of research include molten salt corrosion, high-temperature gas and water corrosion, irradiation effects on microchemistry and microstructure of structural materials. To achieve these objectives, the MaDCoR lab is equipped with state-of-the-art experimental facilities. In addition, a large part of the group’s research focuses on a corrosion model Couet has been developing, called C4 (coupled current charged composition). The model is predictive in nature, and allows engineers to screen and diagnose certain materials based on their strengths.
