A systematic strategy for the calibration of crushed salt constitutive models Open
Crushed salt is aimed to act as long-term barrier in a HLW repository in rock salt. The development of its sealing effect against radionuclide migration is determined by the porosity/permeability evolution governed by crushed salt compacti…

Confidence building in the prediction of crushed salt as long-term barrier Open
The safety concept of a repository in rock salt is based on a multi-barrier system in that barrier’s sealing effects are time dependent. In short-term of the post-closure phase, the safe containment of radionuclides is provided by the wast…

Compaction of crushed salt for safe containment – a summary of the KOMPASS projects Open
For the underground disposal of high-level nuclear waste in rock salt formations, the safety concept includes the backfilling of open cavities with crushed salt. For the prognosis of the sealing function of the backfill for the safe contai…

Compaction of Crushed Salt for Safe Containment - Overview of Phase 2 of the KOMPASS Project Open
Crushed salt may be used as backfill material and sealing measures of open cavities, drifts and shafts in nuclear waste repositories located in rock salt formations. The host rock salt will gradually compact the crushed over time due to sa…

Compaction of crushed salt for safe containment – Overview of phase 2 of the KOMPASS project Open
The KOMPASS project strives to improve the scientific basis behind using crushed salt for long-term isolation of high-level nuclear waste within rock salt repositories. Efforts to improve the prediction of crushed salt compaction began dur…
