The SKB Task Force on Engineered Barriers
The objective of the Task Force on Engineered Barriers is development of general and effective tools for the advanced coupled THMC analysis of buffer and backfill behaviour.
The goals of the THM group are to:
- verify the capability to model THM processes in unsaturated as well as saturated bentonite buffer and backfill materials
- validate and further develop material models and computer codes by numerical THM modelling of laboratory and field tests and compare modelling results with measured results
- evaluate the influence of parameter variations, parameter uncertainties and model imperfections
- develop the codes to 3D standard
The goals of the C group are to:
- develop models and concepts for reactive transport
- link the atomic scale to the macroscopic scale in bentonite
- test numerical tools on provided experimental data (benchmark testing)
