Implementing Geological Disposal of Radioactive Waste Technology Platform
The project will investigate how surfaces of solids with a flourite structure – UO2, ThO2, CeO2 and CaF2 - change with time during dissolution, and how those changes affect the dissolution rate.
Laboratory experiments monitoring dissolution of crushed synthetic material will be performed, in connection with first principles calculations. The experimental data will guide the calculations, and vice versa, to develop a computational model of how the surfaces of flourite-structures evolve during dissolution.
The final aim of the REDUPP project is to reduce the uncertainties in the spent nuclear fuel dissolution rates used when assessing the long-term safety of geological disposal concepts of nuclear waste.
