Description
For the copper plate (copper metal surface), no sorptio reactions are expected to take place. In the concrete part of the bottom plate, radionuclides and major ions may undergo a range of interactions with the matrix (hardened cement paste). In comparison, interaction with the aggregate material can often be neglected. Exception to this may be sorption of simple cations, especially Cs, to layer silicate materials contained in the aggregate material derived from crystalline rock, see FEP CA11.
