Previous studies on chemical durability of radioactive waste forms mainly focused on samples containing no radionuclides. We performed a hydrothermal experiment with several variably self-irradiated natural titanites and the leaching results indicate that radiation damage has some influence over chemical durability through its ability to change the microstructures of materials, including cracks, holes, interconnected amorphous clusters, and nano-sized defects. However, chemical durability is not influenced if the variation in local microstructures induced by radiation damage is insignificant.

辐射损伤对钛矿结构和化学耐久性的影响。

先前对放射性废物形式的化学耐久性的研究主要集中在不含放射性核素的样品上。我们用几种可变的自辐照天然钛矿进行了水热实验，浸出结果表明，辐射损伤通过改变材料的微观结构（包括裂纹，孔洞，相互连接的无定形簇和纳米尺寸）的能力，对化学耐久性有一定影响。缺陷。但是，如果由辐射损伤引起的局部微观结构变化不明显，则化学耐久性不会受到影响。
