60 Years of U: Perspectives on resources, demand, and the evolving role of nuclear energy
Recent years have seen growing global interest in nuclear energy and rising confidence in the sector. For the first time since the early 2000s, there is renewed optimism about the industry’s future. This change is driven by several major factors: geopolitical developments that highlight the need for secure energy supplies, a stronger focus on resilient energy systems, national commitments to decarbonization, and rising demand for clean and reliable electricity.

The design of underground and closure structures for the Cigeo repository is mainly based on geomechanical constitutive models tested in the Meuse/Haute-Marne URL. Excavation modes adapted to the different repository components have been evaluated and tested. Specific methods for excavation and lining have been designed for access shafts and ramps, ILW and HLW disposal cells as well as sealing systems located in surface-to-bottom infrastructures and in drifts.
