FEP Effects
Description of FEP Effects
The stress field in the EBS will be determined by the regional stress field and by local changes to the stress field caused by excavation, waste emplacement and thermal evolution of the EBS. After re-saturation of the GDF, the supercontainer will be subject to hydrostatic pressure. Changes to these stresses could damage components of the EBS.
