Explanation of how the FEP is treated

Intact canister, Resaturation/ "thermal" period: Neglected under unsaturated conditions since the extent of aqueous reactions is limited. For saturated conditions the treatment is the same as for "Long term". Intact canister, Long-term after saturation and "thermal" period: Microbial effects in the central area are included in the description of the geochemistry in the repository.
