我们报告了英国 HLW MW+25% 模拟玻璃在同地地质处置设施的模型超碱性条件下的化学耐久性分析。将玻璃粉末和整料在饱和 Ca(OH)(2) 中溶解 168 天。高浓度 Ca（>200mg/L）存在下的溶解度比水中的溶解度低一个数量级。直到 Ca:Si 比例达到
We report analysis of chemical durability of UK HLW MW+25% simulant glass under model hyperalkaline conditions of a colocated geological disposal facility. Glass powders and monoliths were dissolved for 168days in saturated Ca(OH)(2). Dissolution in the presence of high concentrations of Ca (>200mg/L) was an order of magnitude lower than dissolution in water. Dissolution of Si did not occur until a Ca:Si ratio of
