Description
Transport of solutes (dissolved substances) and colloids with the water in the backfill by pressure-induced flow: advection.
SKB Number
SKB FEP Number
BfT09
Main Category
Main category for FEP
Internal process
System Component
System component to which the FEP applies
Backfill in tunnels
Handling
Explanation of how the FEP is treated
Intact canister - Resaturation/ "thermal" period. Simplified assumptions of mass transport of dissolved species during saturation.
Intact canister - Long-term after saturation and "thermal" period. Included in geosphere modelling. Cases without the backfill path are considered.
