Numerical modelingmodeling of the long term mechanical behaviour of underground storages
In this paper, a storage cell for the high level radioactive wastes is studied in order to identify and demonstrate the coupled phenomena evolving in the high level wasts (HLW) storage. According to the various important processes in the storage structures, special attention is paid on the coupling corrosion/strain processes. Due to the arrival of water from the geological formation, the metallic components will be corroded. As a result, its mechanical resistances reduce and an additional volume will be generated with the progression of corrosion. In the calculations, different materials are taken into account in the numerical simulations: argillite, steel and air. Based on the experimental investigations, different constitutive models are applied to every mentalinvestigations,differentconstitutivemodelsareappliedtoeverymaterial. These numerical calculations allow us to obtain some quantitative results describing the mechanical behaviour and coupling thermo-hydromechanical processes for a short-and long-term in the storage cell.
