Colloid and Radionuclide Retardation (CRR) - Experimental Concept

The experimental concept is based on the scenario shown below where the EBS-released radionuclides and the bentonite-derived colloids enter the host rock groundwater and migrate along a water-conducting fracture.

The GTS underground facilities are also available to interested 3rd parties for underground testing and research. The GTS offers cost-effective access to a fully developed, well characterised underground research facility with round the year logistical support - please contact Dr. Ingo Blechschmidt, Head of the Grimsel Test Site, for further details.
