锆英石(CaZrTi2O7)、烧绿石(VIIIA2 VIB2 IV X6Y)和钙钛矿(CaTiO 3)是用于固定各种高放射性废物(HLW)形式1中的稀土元素(RE E)和锕系元素(ACT)的候选相。辐射损伤对结构的影响,从而对这些阶段的耐久性是重要的,他们的行为在处置库环境和风险评估的预测建模。
Zirconolite (CaZrTi2O7), pyrochlore (VIIIA2 VIB2 IV X6Y) and perovskite (CaTiO3) are candidate phases for the immobilisation of rare earth elements (REEs) and actinides (ACTs) in various high level radioactive waste (HLW) forms 1. The effect of radiation damage on the structure and consequently on the durability of these phases is important to predictive modelling of their behaviour in the repository environment and risk assessment.
