Study at laboratory scale of the effects of the thermal gradient generated from the metallic container of radioactive waste, (simulated by carbon steel disks heated at 100-120 ºC), and the hydraulic gradient generated by a clayey host rock (simulated by the infiltration of saline solution at 1-2 MPa) on compacted bentonite blocks used as engineered barrier for radioactive waste confinement. The types of bentonite are studied: MX-80, FEBEX (reference bentonite in the Spanish concept for HLRW confinement) and a FEBEX bentonite saturated in Mg.
