NEUP CINR-17-12628: Effects of Mineral Impurities and Heat on Uranium(VI) Sorption onto Bentonite

Mineral impurities are common in bentonite and clay buffer materials, proposed for many nuclear waste disposal options. We will investigate the effects of calcite impurities on uranium(VI) sorption onto montmorillonite before and after mineral exposure to heat. Based on experimental sorption data and EXAFS analysis we will develop a new surface complexation model to determine under which conditions impurity effects are relevant, and how they can be incorporated in performance assessment models.
