Explanation of how the FEP is treated
Intact canister, Resaturation/ "thermal" period: No specific assessment of the saturation of the borehole seals is done. The process is expected to be rather fast since the diameter is small. For post-saturation, see "long-term".
Intact canister, Long-term after saturation and "thermal" period: Evaluation of swelling pressure and hydraulic conductivity of the bentonite part of the seal through comparison with empirical data.
