Explanation of how the FEP is treated
Excavation/operation: Neglected because of insignificant impact on geochemical conditions. Impact on radionuclide transport not relevant because of intact barriers.
Temperate: Neglected because of insignificant impact on geochemical conditions.
Bounding calculations of colloid-facilitated radionuclide transport performed.
Periglacial: Neglected because of insignificant impact on geochemical conditions.
Bounding calculations of colloid-facilitated radionuclide transport performed.
Glacial: Neglected because of insignificant impact on geochemical conditions.
Bounding calculations of colloid-facilitated radionuclide transport performed.
Earthquakes: Impact of earthquakes on colloidal processes not addressed, but simplified calculations of radionuclide transport carried out (see Ge24).
