Pushing the boundaries of materials science

Nuclear reactor systems support approximately 15% of Canada’s energy production, with a substantial 60% contribution in Ontario alone. In an evolving landscape of new energy technologies, the demands for enhanced performance of nuclear energy in increasingly rigorous environments and conditions are high. While conventional alloy development and traditional approaches have yielded some notable advancements, they still fall short of meeting these escalating demands. Understanding the intricate mechanisms behind alloy performance is challenging, and a comprehension of fundamental processes remains elusive, impeding the design of materials essential for the deployment of safer, longer-lasting reactors.

Through a multidisciplinary lens that incorporates experimental and computational methods, Dr. Yanwen Zhang’s research integrates both a science-driven exploration of model concentrated solid-solution alloys and experience-informed analysis of conventional dilute alloys. Her research aims to realistically predict alloy degradation, while uncovering insights into self-healing mechanisms, structural stability, and deformation tolerance under high stress, temperature, radiation, and other extreme material conditions. Through collaborative efforts with academic partners, national labs, and the nuclear industry, this work has the potential to impact various sectors, enhance the efficiency, reliability, safety, and cost-effectiveness of nuclear energy systems, as well as contribute to the safe disposal of spent nuclear fuel. Ultimately, this research seeks to usher in a new era of safe, resilient, and high-performing nuclear energy solutions that will support Canada in its transition to a low-carbon future.
