Clays and clay rocks are considered good natural engineered barriers for deep geological disposal of nuclear waste worldwide. Metal corrosion organic degradation in underground repositories generate significant amounts gas that should be able to migrate through the multibarrier system avoid potential pressure buildup, which could compromising integrity host rocks. The is expected accumulate lar...

Résumé. The two test cases presented herein aimed at simulating the transport migration of nuclides around a nuclear waste repository and belong to the "Two-Phases Numerical Test Data Base" presented in [1], [2]. They were initially designed in the framework of the French research group MoMaS [3]. The starting point in designing all the test cases presented in [1] comes from some of the main ch...
