Description

The most important mechanism under saturated conditions is transport of water in liquid phase, which is driven by a water pressure gradient, see FEP Bu04.

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.
