Propriétés de transfert des géomatériaux pour le stockage des déchets radioactifs en formation géologique
ABSTRACT To prevent the dissemination of radionuclides at different timescales, a deep geological repository is assigned a number of safety functions, which complement each other to optimise the system's overall performance. Transfer properties have been studied for each confinment barriers in agreement with the environmental context of a disposal. Measurement methodologies have to cope with very low permeabilities and diffusivities. Uncertainties on the data have been dramatically reduced. R&D axes aim at understanding processes at a microscopic scale to better assess how they are modified with time and how the different barriers interact with each others.
