Description

The integrated aspects of processes involved in transport of radionuclides in the water phase, i.e. advection and dispersion (mixing), diffusion and rock-matrix diffusion, sorption and speciation, colloid transport and radioactive decay.

Explanation of how the FEP is treated

Excavation/operation: Not relevant since engineered barriers are intact. Temperate: Advection, dispersion, matrix diffusion, sorption, and radioactive decay included in integrated modelling using FARF31 and MARFA. Periglacial: Advection, dispersion, matrix diffusion, sorption, and radioactive decay included in integrated modelling using FARF31 and MARFA. Glacial: Advection, dispersion, matrix diffusion, sorption, and radioactive decay included in integrated modelling using FARF31 and MARFA. Earthquakes: No credit taken for radionuclide retention in the geosphere i.e.geosphere far field is short-circuited.
