Description
The high chemical gradient at the concrete/host rock interface may be a source of colloidal particles to which radionuclides can become attached (sorption, incorporation). These colloids are likely to be immobile in the fine pore structure of the undisturbed Opalinus Clay (filtration), and may lead to clogging of Opalinus Clay pores.
