Explanation of how the FEP is treated
Excavation/operation: Neglected since reactions are considered to be insignificant compared with the effects of reactions with fracture-filling minerals.
Temperate: Neglected since reactions are considered to be insignificant compared with the effects of reactions with fracture-filling minerals.
Periglacial: Neglected since reactions are considered to be insignificant compared with the effects of reactions with fracture-filling minerals.
Glacial: Modelling of oxygen penetration based on the groundwater flow modelling, matrix diffusion and reactions with matrix minerals.
Earthquakes: Not relevant.
