The following five requirements must be fulfilled in order that colloid-facilitated transport of radionuclides in a potential repository host rock would be of significance to the long-term performance of a waste repository:
Colloids must be : present, mobile and stable under the given groundwater conditions (geochemical and hydrogeological environment), radionuclide association with the colloids must take place and the association must be irreversible.
Therefore the first outcomes of the CRR experiment are related to these five fundamental questions.
