Nuclear electricity/heat is a safe source of green and inexpensive electricity/ heat when there are appropriate measures to deal with the radiation. Being able to measure the effects of radiation and chemical corrosion on materials in different stages in the nuclear industry can give a critical edge to industry operation and design of any equipment related to the use and handling of radioactive materials. In this research program we are planning to develop such an understanding, that is of economic importance and in line with the environmental benefit of nuclear electricity, within Canada and at a global level. We will provide a detailed knowledge of corrosion not only at the surface but also under the surface at different depths as a function of time and this will help to prevent damages which in turn will result in better asset management.The Nuclear Energy Division (NED) is the unit within the Energy Sector that develops and implements Canadian government policy on nuclear energy. NED brought together provinces, territories, and utilities to undertake a pan-Canadian roadmap for the Small Modular Reactors (SMR), known as the SMR Roadmap. Advancing of SMR research and development in collaboration with appropriate international partners was one of the recommendations; and Canada's participation in the Generation IV International Forum is aligned with it. The SMR Action Plan recognizes SMRs as an opportunity for Canada to deliver on its energy priorities, while unlocking a range of complementary benefits: environmental, economic, geopolitical, and social. Our research can benefit SMRs of any class. It will help to develop better chemical environments in core, as well as efficient and safe storage of spent nuclear fuels. In any reactor (CANDU or SMR), determining the time dependence and modes of inhibition of chemical and radiation-based corrosion has profound implications on reactor operation, impacting both long-term performance and reliability of the reactor, as well as informing methodological chemical control decisions. Corrosion in core material and equipment can not only reduce the lifetime efficiency of a reactor, but if left unchecked, may lead to unexpected failure of equipment.

如果有处理辐射的适当措施，核电/热是一种安全的绿色和廉价的电/热来源。能够测量辐射和化学腐蚀对核工业不同阶段材料的影响，可以为工业运营和与使用和处理放射性材料有关的任何设备的设计提供关键优势。在这项研究计划中，我们计划在加拿大国内和全球范围内建立这样一种理解，即具有经济重要性，并与核电的环境效益保持一致。我们将不仅提供表面腐蚀的详细知识，而且还提供随着时间的变化而在不同深度的表面下的腐蚀的详细知识，这将有助于防止损害，这反过来将导致更好的资产管理。核能部门(NED)是能源部门内制定和执行加拿大政府核能政策的单位。NED将各省、地区和公用事业公司聚集在一起，为小型模块化反应堆(SMR)制定了一份泛加拿大路线图，称为SMR路线图。建议之一是与适当的国际伙伴合作推进工作人员-管理层关系的研究和开发；加拿大参加第四代国际论坛也与此一致。SMR行动计划承认SMR是加拿大实现其能源优先事项的机会，同时释放了一系列互补利益：环境、经济、地缘政治和社会。我们的研究可以使任何班级的SMR受益。它将有助于在堆芯中发展更好的化学环境，以及有效和安全地储存乏核燃料。在任何反应堆(CANDU或SMR)中，确定化学腐蚀和基于辐射的腐蚀的时间依赖性和抑制模式对反应堆的运行具有深远的影响，影响反应堆的长期性能和可靠性，并为化学控制决策提供信息。堆芯材料和设备的腐蚀不仅会降低反应堆的寿命效率，而且如果不加以控制，可能会导致设备的意外故障。
