The thesis research will focus on studies of nanoparticulate bentonite clay colloids. These studies are fundamental to understanding how the material would act as a buffer in a geological disposal facility, sitting between the canisters containing high level nuclear waste and the walls of the bore holes where they will sit. The information that is sought is to form a better understanding of the selective binding of several cations (Cs, Ni and Eu), how these are affected by the average size of the colloid particles and how the colloid assists in transporting these through granite fissures. Specific aspects will include studying different ways to produce the colloids, size them and measure their flow.

本论文的研究重点是纳米膨润土胶体的研究。这些研究对于理解这种材料如何在地质处置设施中充当缓冲区是至关重要的，它位于含有高水平核废料的罐和它们将位于的钻孔壁之间。所寻求的信息是为了更好地了解几种阳离子（Cs，Ni和Eu）的选择性结合，这些如何受到胶体颗粒的平均尺寸的影响，以及胶体如何帮助通过花岗岩裂缝运输这些。具体方面将包括研究生产胶体的不同方法，确定其大小并测量其流量。
