Explanation of how the FEP is treated
Intact canister, Resaturation/ "thermal" period: No specific assessment of the saturation of borehole seals is done. The process is expected to be rather fast since the diamteter is small.
Intact canister, Long-term after saturation and "thermal" period: Neglected, no gas is expected to enter the borehole seals.
