Explanation of how the FEP is treated

Intact canister, Resaturation/ "thermal" period: Neglected. Due to the distance, chemical processes in this component will have limited impact on the performance of the rest of the repository. The hydraulic conductivity of this component will under all circumstances be high. Intact canister, Long-term after saturation and "thermal" period: Neglected. Due to the distance, chemical processes in this component will have limited impact on the performance of the rest of the repository.
