Nuclear power provides a large fraction of the electricity needed to meet the energy requirements of Canada and many other industrialized countries. It is one of the few proven technologies that can supply large-scale base-load electricity without generating greenhouse gases. This is particularly important in the province of Ontario where nuclear power already supplies 50% of the electrical energy consumed. Sustained operation of nuclear power plants is expected to be a part of our future balanced energy supply strategy. Key requirements for public acceptance of nuclear power are the safe operation of reactors and the implementation of a safe system for the long-term storage of spent nuclear fuel. A challenge facing both of these needs is potential corrosion where ionizing radiation is present. This can affect the integrity and lifetimes of reactor structures and the spent fuel waste containers. The Chair program is aimed at developing the knowledge and tools to address these and other issues arising from radiation-induced corrosion. The Chair and her group have previously established a world-leading laboratory for radiation-assisted corrosion studies. In collaboration with materials research groups at Western, Canadian research laboratories, and other institutes around the world, sophisticated corrosion studies have been performed. This has led to fundamental understanding of: (1) steady-state water radiolysis chemistry, (2) radiation-induced uniform corrosion of reactor materials (carbon steel and stainless steel and cobalt alloys), and (3) the radiolytic formation of solid oxide nanoparticles following corrosion. In the 3rd term of the IRC program, the Chair's research will be extended to address radiolysis chemistry in humid air and confined volumes. It will focus on corrosion in locations such as weld cracks or crevices. These environments are particularly important in addressing Canadian industry needs.

核电提供了满足加拿大和许多其他工业化国家能源需求所需电力的很大一部分。它是为数不多的能够提供大规模基本负荷电力而不产生温室气体的成熟技术之一。这对于安大略省尤为重要，该省的50%的电能已经由核电提供。核电站的持续运行预计将成为我们未来平衡能源供应战略的一部分。 公众接受核电的关键要求是反应堆的安全运行和乏核燃料长期储存的安全系统的实施。这两种需求面临的挑战是存在电离辐射的地方的潜在腐蚀。这会影响反应堆结构和乏燃料废物容器的完整性和寿命。主席计划旨在开发知识和工具来解决由辐射引起的腐蚀引起的这些问题和其他问题。 主席和她的团队此前已建立了世界领先的辐射辅助腐蚀研究实验室。与西方、加拿大研究实验室和世界各地其他机构的材料研究小组合作，进行了复杂的腐蚀研究。这导致了对以下方面的基本理解：(1) 稳态水辐射分解化学，(2) 辐射引起的反应堆材料（碳钢、不锈钢和钴合金）的均匀腐蚀，以及 (3) 固体氧化物的辐射分解形成腐蚀后的纳米颗粒。在 IRC 项目的第三个任期中，主席的研究将扩展到解决潮湿空气和密闭空间中的辐射分解化学问题。它将重点关注焊缝裂纹或缝隙等位置的腐蚀。这些环境对于满足加拿大工业需求尤其重要。
