Full-scale Engineered Barriers Experiment FEBEXe - Aims
The initial aim of the FEBEX experiment, back in 1997, was to study the behaviour of the nearfield components (EBS, host rock) for a high-level radioactive waste repository in crystalline rock.
- Previous prediction/evaluation exercises indicated that the resaturation phase is poorly understood
- There is a significant underestimation of resaturation times
- Uncertainties in some key parameters (the evolution of thermal conductivity of partially saturated buffer, the scale dependence of measured thermal conductivities) are remaining
