Description
Freezing of the bottom plate is of no significance, since no long-term performance is expected from the concrete. The same process takes place in the material around the bottom plate as described in the corresponding process description for the buffer, see FEP Bu03. The bottom plate will not change anything in respect to freezing and thawing.

Handling
Explanation of how the FEP is treated
Intact canister, Resaturation/ "thermal period: Neglected since this requires permafrost conditions.
Intact canister, Long-term after saturation and "thermal" period: Of no significance since no long-term performance is expected from the bottom plate.
