Explanation of how the FEP is treated

Intact canister - Resaturation/ "thermal" period. Neglected since dose rate outside canister is too low to have any effect. Intact canister - Long-term after saturation and "thermal" period. Neglected since dose rate outside canister is too low to have any effect. Intact canister - Earthquakes. Neglected since dose rate outside canister is too low to have any effect. Failed canister - Resaturation/ "thermal" period. Neglected since dose rate outside canister is too low to have any effect. Failed canister - Long-term after saturation and "thermal" period. The effect of a-radiation from nuclides from a failed canister is estimated. Failed canister - Earthquakes. The effect of a-radiation from nuclides from a failed canister is estimated.
