Effects of osmosis on tunnel backfill characteristics (swelling pressure and hydraulic conductivity) .
SKB Number
SKB FEP Number
BfT14
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. Hydraulic conductivity in THM model chosen so as to handle the effect of salinity.
Intact canister - Long-term after saturation and "thermal" period. Evaluation through comparison with empirical data.
