To investigate the aqueous durability of UK nuclear waste glasses. The project involves making the link between the behaviour of complex glasses and their simplified analogues from which mechanistic information on dissolution and passivation can be determined. Simplified borosilicate glasses will be formulated to mimic the behaviour of the complex glasses presenting at the UK waste vitrification plant at Sellafield. A combination of ICP-MS, electron microscopy and nuclear magnetic resonance measurements of glasses will be made to determine the nature of the alteration layer on the glass surface and its influence on the overall level of glass dissolution.

研究英国核废料玻璃的水耐久性。该项目涉及在复杂玻璃的行为与其简化的类似物之间建立联系，从中可以确定有关溶解和钝化的机械信息。简化的硼硅酸盐玻璃的配方将模仿英国塞拉菲尔德废物玻璃化工厂生产的复杂玻璃的行为。将结合ICP-MS、电子显微镜和核磁共振测量玻璃，以确定玻璃表面蚀变层的性质及其对玻璃溶解总体水平的影响。
