The aims of the CFM project with its laboratory, in-situ and modelling approaches are to:
- Examine colloid generation rates and mechanisms at the Engineered Barrier System (EBS) – host rock boundary under in-situ conditions
- Evaluate the long-distance(~10m scale) migration behaviour of EBS-derived colloids in a water-conducting feature in a repository relevant flow system (i.e. with a very low flow rate/water flux)
- Study the long-term geochemical behaviour (mobility, mineralisation, colloid formation, etc.) of radionuclides at the EBS – host rock boundary
- Examine the reversibility of radionuclide uptake onto colloids
- Gain experience in long-term monitoring of radionuclide/colloid propagation near a repository
- Apply the results to improve repository performance assessments
- Contribute to the optimisation of EBS design and to the 'monitoring' debate
