Description
The hydraulic conductivity of a degraded plug may be high and transport of dissolved species may be rapid, but since the geometry is restricted, the plug will not affect the overall transport pattern in the repository.

Explanation of how the FEP is treated
Failed canister, Resaturation/ "thermal" period: Assumed to be part of the tunnel with high hydraulic conductivity (no failures are expected this period).
Failed canister, Long-term after saturation and "thermal" period: Assumed to be part of the tunnel with high hydraulic conductivity.
