Description

These are also sometimes called Onsagerian processes. Examples include thermal diffusion (transport of solutes due to temperature gradients), chemical osmosis (flow of solution caused by chemical potential gradients across a semi-permeable membrane), hyperfiltration (flow of solutes across a semi-permeable membrane that lets water flow by advection, but prevents solutes from doing so), and thermal osmosis (flow of solution in a porous medium down a temperature gradient).

Description of FEP Effects

Coupled transport processes could affect radionuclide transport, albeit such effects are likely to be minor in comparison to other effects.
