Full-scale Engineered Barriers Experiment FEBEXe - Observations & Results
As the experiment is running now over more than 12 years, a unique dataset including crucial long-term observations in terms of sealing, saturation and corrosion is generated.
- Temperatures in the bottom part continue being higher than those in the sides and upper part for each section. Temperature trends are increasing very slowly in the buffer and in the rock close to the heater.
- The total pressure in general continues increasing in the buffer and also in the contact bentonite/rock and bentonite/plug.
- The water content in the buffer continues increasing at all points. The biggest differences can be observed in the inner part but it is clearly rising elsewhere.
