Effects of Cement on CLAY barrier performance - phase II

Objetivo

Cements will be used intensively in radioactive waste repositories. During their degradation in time, in contact with geological pore water, they will release hyper-alkaline fluids rich in calcium and alkaline cations. This will induce geochemical transformations that will modify the containment properties of the different barriers (geological media and EBS, i.e. clay-based engineered barriers). ECOCLAY I identified major geochemical reactions between bentonite and cement. ECOCLAY II proposes to investigate aspects such as radionuclides sorption, kinetics of the geochemical reactions, coupled geochemistry / transport processes, conceptual and numerical modelling and performance assessment. The whole hyper-alkaline plume (EBS, clay and granite host rock) will be studied within the project. To do so, ECOCLAY II brings together the efforts of 8 European countries on this subject with an aim of supplementing studies.
