The 2011 Tohoku Earthquake and Tsunami catastrophe in Japan gave a clear message to every country that relies on nuclear energy of the urgent need to ensure that its nuclear infrastructure is resilient and possesses adequate redundancy and robustness in the event of natural disasters. Recent work conducted by the US Geological Survey and in Canada has shown that previous seismological studies, based on outdated geological data, dramatically underestimated the level of seismic hazard east of the Rocky Mountains (where all the currently operational Canadian nuclear infrastructure is located). This situation has created a critical need for major seismic qualification efforts within the Canadian nuclear energy industry. **The CaNRisk program relates to the seismic safety assessment and resilience enhancement of nuclear power plants (NPP) following an interdisciplinary system-level approach. The program training will focus on quantifying the probability of failure of critical structures, systems, and components in NPP reactor safety systems under different seismic hazard levels. The generated fragility data are essential to develop a scientifically rigorous framework for probabilistic risk assessment, which is emerging as the best practice for quantifying NPP resilience. The CaNRisk program also focuses on minimizing the environmental risk of spent nuclear fuel to be permanently stored within the planned Canadian Deep Geologic Repository. The proposed interdisciplinary academic training will be integrated with hands-on industrial internship and professional development experiences to facilitate smooth transition of the program trainees to the workforce. **Through meeting its objectives, the CaNRisk program will generate crucial knowledge that will continue to be in demand -especially as Canada's dependence on fossil fuels is reduced. Through its knowledge mobilization approach from the academia to industrial applications, the program will also position Canada as the world leader in nuclear resilience and sustainability technologies and develop the next generation of industry leaders in Canada and internationally.

2011年日本东北部地震和海啸灾难向依赖核能的每个国家发出了明确的信息，即迫切需要确保其核基础设施在发生自然灾害时具有复原力，并拥有足够的冗余和稳健性。美国地质调查局和加拿大最近进行的工作表明，以前的地震研究基于过时的地质数据，大大低估了落基山脉以东的地震危险程度（加拿大目前所有运行的核基础设施都位于那里）。这种情况造成了加拿大核能行业内的主要地震鉴定工作的迫切需要。** CaNRisk计划涉及采用跨学科系统级方法进行核电厂（NPP）的地震安全评估和恢复力增强。该项目培训的重点是量化不同地震危险等级下核电站反应堆安全系统中关键结构、系统和部件的失效概率。生成的脆弱性数据对于制定科学严谨的概率风险评估框架至关重要，这正在成为量化NPP弹性的最佳实践。CaNRisk计划还侧重于尽量减少永久储存在计划中的加拿大深层地质储存库内的乏核燃料的环境风险。拟议的跨学科学术培训将与实际工业实习和专业发展经验相结合，以促进计划学员顺利过渡到劳动力市场。** 通过实现其目标，CaNRisk计划将产生将继续需要的关键知识-特别是随着加拿大对化石燃料的依赖减少。通过从学术界到工业应用的知识动员方法，该计划还将使加拿大成为核弹性和可持续性技术的世界领导者，并在加拿大和国际上培养下一代行业领导者。
