Abstract The French reference SON68 nuclear waste glass corrosion under H2O and D2O18 atmosphere was investigated at 35−125 °C and different relative humidities (92–99.9%). The hydration kinetic was followed by FTIR and solid characterization was achieved using SEM/EDX, Raman and TOF-SIMS. The water diffusion coefficients in the glass ranged from 8.7 × 10−22 to 5.3 × 10−19 m2 s−1. The alteration products were calcite, apatite, powellite and tobermorite. Pre-hydrated glass alteration in synthetic groundwater at 50 °C showed an instantaneous release of elements from the surface, making it important to evaluate well the vapour hydration period of the glass.

SON68 核废料玻璃在不饱和 H 2 O 和 D 2 O 18 蒸气条件下从 35 °C 变化到 125 °C 的动力学研究和结构演化

摘要 研究了法国参考 SON68 核废料玻璃在 H2O 和 D2O18 气氛下在 35-125 °C 和不同相对湿度 (92-99.9%) 下的腐蚀。水合动力学之后是 FTIR，并使用 SEM/EDX、拉曼和 TOF-SIMS 实现固体表征。玻璃中的水扩散系数范围从 8.7 × 10-22 到 5.3 × 10-19 m2 s-1。蚀变产物为方解石、磷灰石、powellite 和 tobermorite。50 °C 合成地下水中的预水化玻璃变质显示元素从表面瞬时释放，这使得很好地评估玻璃的蒸汽水化时间很重要。
