Modelling of radionuclides migration in the low pH cement / clay interface
Abstract (englisch):
Reactive transport modelling activities described in this work are focused on the definition of the conceptual
model and the selection of the chemical and transport parameters to be applied on laboratory through diffusion experiments performed in KIT-INE (see contribution of Ait Mouheb et al., this proceedings). The model includes different coupled processes which are thought to play a role in a through diffusion experiment of HTO, 36Cl-, 129Iand Be across the interface between bentonite porewater and low pH cement. One of these processes is the impact of porosity changes due to dissolution / precipitation reactions.
