Explanation of how the FEP is treated
Intact canister - Resaturation/ "thermal" period. Through dissolution.
Intact canister - Long-term after saturation and "thermal" period. (Through dissolution) No gas phase is assumed to be present.
Intact canister - Earthquakes. (Through dissolution) No gas phase is assumed to be present.
Failed canister - Resaturation/ "thermal" period. Quantitative estimate based on empirical data (no failures are expected this period).
Failed canister - Long-term after saturation and "thermal" period. Quantitative estimate based on empirical data.
Failed canister - Earthquakes. Quantitative estimate based on empirical data.
