Paper presented at the 57th U.S. Rock Mechanics/Geomechanics Symposium, June 25–28, 2023
Paper Number: ARMA-2023-0341
... ABSTRACT In Germany, rock salt is considered as a possible host rock formation for a repository for high-level nuclear waste. Crushed salt will be used for backfilling and sealing measures of open drifts and shafts, providing the tightness of the repository and the safe containment...

Paper presented at the 57th U.S. Rock Mechanics/Geomechanics Symposium, June 25–28, 2023
Paper Number: ARMA-2023-0356
... ABSTRACT The very low permeability of intact salt rocks makes them promising media for the geologic disposal of nuclear waste. However, permeating flow can occur through fractures in rock salt. These fractures can be induced by excavation operations that create a localized damage rock zone...
