Abstract

After introducing the specific features of nuclear waste there follows an account of the main features of the deep geological disposal option. A fully coupled thermo-hydromechanical formulation developed to perform numerical analysis of underground repositories in the near field is described. The formulation is able to take into account the main phenomena that occur in the engineered barrier and immediately adjacent rock. Two examples of application are presented. The first one involves the analysis of a proposed repository scheme excavated in mudstone. The second one concerns the analysis of a large scale in situ heating test in rock salt where the barrier material is crushed salt. The modifications required to account for the behavior of saline materials are noted. The applications presented demonstrate the capability of the formulation to tackle engineering problems and constitute a good illustration of the potential of these methods to provide an enhanced understanding of repository behaviour.
