Description

The bottom plate will be saturated before the deposition of the buffer and the canister. The saturation phase is therefore of no concern in the assessment (see also FEP BP03).

Explanation of how the FEP is treated

Intact canister, Resaturation/ "thermal period: No specific assessment of the saturation of the bottom plate is done. Intact canister, Long-term after saturation and "thermal" period: Neglected - any affect from the bottom plate on gas migration would be positive, since it could act as a sink for released gas. However,the effect is impossible to quantify.
