CRR - Radionuclide Migration Programme

The Radionuclide Migration Programme was a 10 year project carried out in shear zone AU 96 in the GTS along with parallel experiments at JNC's former URL at Kamaishi, north east Japan. The overall aim of the project was to examine the retardation of radionuclides in this shear zone. The first phase of the project involved extensive characterisation of the chemical and physical properties of this shear zone (Geology / Hydrogeology / Hydrology / etc).

The data from the extensive characterisation was used to create models that would predict the behaviour of radionuclides in a repository host rock. These models were then tested by carefully adding safety-relevant radionuclides to the shear zone and observing their in situ retardation behaviour.


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.
