Alteration of vitrified radioactive waste in low temperature natural environments: a natural analogue approach.

这个项目的重点是确定核废料玻璃在地质处置设施中的长期(&10000年)行为。该项目将利用“自然模拟实验”，即玻璃暴露在与放射性废物处理相关的自然环境中数十至数百年。一个关键的结果将是将玻璃在这些复杂的低温环境中的变化与在高温实验室溶解测试中观察到的变化进行比较。博士将致力于对复杂环境中玻璃耐久性的详细机制理解，同时考虑到地下水组成、邻近矿物学和微生物如何影响玻璃腐蚀过程。

This project focuses on determining the long-term (>10,000 yrs) behavior of nuclear waste glass within a geological disposal facility. The project will utilize 'natural analogue experiments', where glasses have been exposed to natural environments with conditions of relevance to radioactive waste disposal for tens to hundreds of years. A key outcome will be to compare glass alteration in these complex low temperature environments, with alteration observed in high temperature, laboratory dissolution tests. The PhD will work towards a detailed mechanistic understanding of glass durability in complex environments taking into account of how groundwater composition, adjacent mineralogy and microbiology affect the glass corrosion process.
