Graphite is used as the moderator in EDF Energy nuclear Advanced Gas Cooled Reactors. It also plays a structural role and the integrity of graphite components has a high impact on plant lifetime economics. The aim of the project is to gain a good understanding and evaluation of fracture in irradiated graphite components by complementary numerical and experimental approaches. An advanced modelling tool allowing automatic simulation of crack propagation in graphite bricks will be developed. An innovative experimental method will be elaborated to validate these models. Uncertainties related to the whole core mechanical behaviour will also be assessed. By supporting the decisions regarding AGRs plant life extensions, it will participate to the security of low carbon electricity supply in the UK in the next years, at affordable and competitive costs.

石墨用作EDF能量核晚期气体冷却反应器中的主持人。它还起着结构性的作用，石墨组成部分的完整性对植物寿命经济学产生了很大影响。该项目的目的是通过互补的数值和实验方法对受辐照的石墨成分中断裂的良好理解和评估。将开发出一种高级建模工具，允许在石墨砖中自动模拟裂纹传播。将详细阐述一种创新的实验方法来验证这些模型。与整个核心机械行为有关的不确定性也将被评估。通过支持有关AGRS植物寿命延长的决定，它将以负担得起的和有竞争力的成本在未来几年参与英国低碳电力供应的安全。
