Description

The volume of the top seal is small enough for its thermal evolution to be completely controlled by the slow and modest change in the temperature of the surrounding rock mass, regardless of the heat transport properties of the top seal materials.

Explanation of how the FEP is treated

Intact canister, Resaturation/ "thermal" period: Temperature as a function of distance from deposition holes is calculated. However, no specific estimate of the temperature in the top seal is made. Intact canister, Long-term after saturation and "thermal" period: Temperature as a function of distance from deposition holes is calculated. However, no specific estimate of the temperature in the top seal is made.
