Résumé / Abstract
In all nuclear power-generating countries, the management of spent nuclear fuel and long-lived radioactive waste is an important environmental issue. Disposal in deep clay geological formations is one of the promising options recommended at the international level. In this concept of the geological disposal system, the host clay formation is considered as a principal barrier on which rests the fulfilment of key safety functions. Hence, preventing unnecessary damage to the host formation is one of the objectives of repository design. A proper evaluation of the excavation-damaged zone (EDZ) in the host formation is, thus, an important issue for the long-term safety of underground disposal. As a side effect of radioactive decay, vitrified high-level wastes and spent fuel release a significant amount of heat, even after several decades of cooling in surface facilities. The influence of the thermal load generated by the radioactive waste on the performance of the disposal system is particula.
