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.
