A Deep Geological Repository (DGR) is the facility intended to store the nuclear waste (Intermediate Level Waste or High-Level Waste) inside a stable geological formation. The DGR is based on the “multibarrier principle” that comprises a series of artificial and natural barriers to isolate the waste from biosphere. Such a unique facility, which is built in a few countries at a depth >500m, will involve the excavation of a network of tunnels in the suitable host rock. Also shafts and ramps will be required to connect with the surface facilities.
Due to the underground conditions and the nature of the waste, complex Thermo-Hydro-Mechanical and Chemical (THCM) processes will take place. Main objective of the DGR is to safely contain the highly pollutant waste for thousands of years. We gained valuable experience by completing successful projects during last 25 years. We support our clients with distinctive specialisation as well as in-depth knowledge in this field. Together, we develop the best solutions.
