Description
Concerns the stimulation of microbial processes due to additives in the concrete bottom plate and consequences in terms of the production of sulphide, acid, gas and complexing agents.
SKB Number
SKB FEP Number
BP14
Main Category
Main category for FEP
Internal process
System Component
System component to which the FEP applies
Bottom plate in deposition holes
Handling
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: Separate assessment of the reactions that can take place in the bottom plate.
