Explanation of how the FEP is treated
Excavation/operation: Composition of groundwater in fractures modelled based on results of the groundwater flow modelling, assumed local mineral equilibria and site understanding.
Temperate: Composition of groundwater in fractures modelled based on results of the groundwater flow modelling, assumed local mineral equilibria and site understanding.
Periglacial: Composition of groundwater in fractures modelled based on results of the groundwater flow modelling, assumed local mineral equilibria and site understanding.
Glacial: Composition of groundwater in fractures modelled based on results of the groundwater flow modelling, assumed local mineral equilibria and site understanding.
Reactions with oxygen are considered in the analyses of oxygen penetration.
Earthquakes: Not relevant.
