Geotechnical centrifuge modeling for simulating long-term radionuclide migration in large-scale fractured rocks

Deep geological disposal is a globally recognized and safe method for long-term management of high-level radioactive waste (HLW). However, over extended periods of nuclear waste storage, there is the potential for the waste canister to experience leaks due to corrosion or alterations in the geological environment. This could lead to the eventual release of radionuclides into the surrounding fractured rock, posing a risk of migration into the biosphere.
