Description

Speciation of solutes and sorption of solutes onto surfaces of water-bearing fractures in the rock and on the surfaces of the microfractures inside the rock matrix, where the water is more or less stagnant.

Explanation of how the FEP is treated

Excavation/operation: Not relevant. Temperate: Simplified Kd-approach for modelling sorption of radionuclides. Speciation considered in the selection of Kd values. Periglacial: Simplified Kd-approach for modelling sorption of radionuclides. Speciation considered in the selection of Kd values. Glacial: Simplified Kd-approach for modelling sorption of radionuclides. Speciation considered in the selection of Kd values. Earthquakes: Not relevant.
