This paper presents a catalogue of possible radiation-induced damage of rock aggregates, which was compiled using the relevant literature and confirmed numerically. The catalogue describes two common and six specific cases of rock aggregate damage. Additionally, the catalogue is supported by a validated numerical model, which is based on Rigid-Body Spring Model. The detailed numerical analysis and the result description of all the cases shown in the catalogue are presented in this paper. The main dependencies are also discussed and the related conclusions are drawn, of which the most important are that the damage of the rock can be delayed and increased rapidly after the delay; even a small amount (1%) of a highly expansive mineral leads to a significant reduction of mechanical properties of the rock; and a partial recovery of the elastic modulus of the rocks is possible even for significantly damaged rocks. It is believed that this paper will help to predict the radiation-induced degradation of rock aggregates as well as support the future development of related analytical models.

本文介绍了岩骨料可能受到辐射损伤的目录，该目录是利用相关文献编制的并经数值证实的。该目录描述了两种常见的岩石骨料损坏情况和六种特殊情况。此外，该目录由基于刚体弹簧模型的经过验证的数值模型提供支持。本文给出了目录中所有案例的详细数值分析和结果描述。还讨论了主要依赖关系并得出了相关结论，其中最重要的是岩石的破坏可以延迟并在延迟后迅速增加；即使少量 (1%) 的高膨胀矿物也会导致岩石的机械性能显着降低；即使对于严重受损的岩石，也可以部分恢复岩石的弹性模量。相信本文将有助于预测岩石骨料的辐射诱导退化，并支持相关分析模型的未来发展。
