核聚变反应堆环境中材料性能的预测依赖于计算模型，并且将继续这样做，直到第一代核聚变发电厂投入使用，并允许观察长期行为。与此同时，模型得到了实验的支持，这些实验试图复制最终操作条件的某些方面。2019年，一群顶尖专家在国际能源署（IEA）的主持下会面，讨论了聚变材料建模的现状和持续挑战，以及先进的实验表征如何帮助模型改进。本次审查取材于该讲习班期间进行的讨论。讨论的主题包括辐照诱导缺陷产生的建模和基本性质，气体行为，聚类和偏析，缺陷演变和相互作用，以及新的和新颖的多尺度模拟方法，以及通过先进的观察和表征技术将建模与实验联系起来的最新努力。
Prediction of material performance in fusion reactor environments relies on computational modelling, and will continue to do so until the first generation of fusion power plants come on line and allow long-term behaviour to be observed. In the meantime, the modelling is supported by experiments that attempt to replicate some aspects of the eventual operational conditions. In 2019, a group of leading experts met under the umbrella of the IEA to discuss the current position and ongoing challenges in modelling of fusion materials and how advanced experimental characterisation is aiding model improvement. This review draws from the discussions held during that workshop.Topics covering modelling of irradiation-induced defect production and fundamental properties, gas behaviour, clustering and segregation, defect evolution and interactions are discussed, as well as new and novel multiscale simulation approaches, and the latest efforts to link modelling to experiments through advanced observation and characterisation techniques.
