FEP Effects
Description of FEP Effects
The EBS could be mechanically disturbed by physico-chemical degradation of the buffer, external forces (e.g. gallery roof or lining collapse, rock creep or faulting in near-field rock), volume increase of corrosion products, and/or the build-up of internal gas pressure. These disturbances could cause processes such as cracking, and movement of the overpack through the buffer.
