Description
The formation of aqueous complexes between radionuclides and anthropogenic or naturally occurring chemical agents such as organic materials. Chemical agents may be present in GDF materials or otherwise be introduced into the GDF, e.g. from spillage of oil, hydraulic fluid, or solvents during GDF construction and operation. Organic compounds may also be present in the host rock and be transported by groundwater into the EBS.

Description of FEP Effects
Complexation of radionuclides with chemical agents in the EBS porewater could affect solubilities and radionuclide speciation, and thus radionuclide migration.
