Coupled thermomechnical effect on the swell pressure and reactive transport through compacted bentonite

Abstract

Deep geological disposal has been considered as one of the best ways to handle higher level nuclear wastes The compacted bentonite or sand bentonite blocks are used as a buffer material in the deep geological repository DGR for the safe disposal of high level nuclear waste HLW due to its favorable physicochemical and hydromechanical properties Buffer surrounding the waste canister experiences variation in the temperature for a long duration of time Such thermal effects are induced when hi...
