Explanation of how the FEP is treated

Intact canister, Resaturation/ "thermal" period: The plug is a part in the integrated treatment of piping. However, no assessment of piping in the plug itself is done. Intact canister, Long-term after saturation and "thermal" period: Neglected since piping only occurs suring the early part of repository evolution.
