Short summary

We studied how crushed salt changes over time so that it can safely seal a future waste repository. By combining new laboratory tests with improved computer models, we created a clearer picture of how the material compacts and when it becomes tight. Our results reduce uncertainty in long‑term predictions and support safer planning for storing radioactive waste underground.
