Borehole seals

Handling

Explanation of how the FEP is treated

Intact canister, Resaturation/ "thermal" period: Can be neglected as long as the bentonite component remains in place. The case of lost sealing is assessed in the modelling of the geosphere. Intact canister, Long-term after saturation and "thermal" period: Can be neglected as long as the bentonite component remains in place. The case of lost sealing is assessed in the modelling of the geosphere.
