Description
The chemical and dissolution processes in which the gases found in the geosphere may be involved. Gaseous species are taken to be substances that exist as gases under the range of temperatures and pressures that include those of the repository and ambient conditions.

Explanation of how the FEP is treated
Excavation/operation: Composition of mixtures modelled based on the groundwater flow modelling, assumed local mineral equilibria and site understanding. This affects the concentrations of dissolved CO2.
Temperate: Modelling of diffusive transport of methane and hydrogen.
Periglacial: Modelling of diffusive transport of methane and hydrogen.
Glacial: Included in modelling of oxygen consumption.
Modelling of diffusive transport of methane and hydrogen.
Earthquakes: Not relevant.
