Our solutions

A large share of the electricity produced today in France and around the world comes from nuclear reactors using enriched uranium.

After several phases of conversion and transformation, and during the various stages of its life cycle, this fuel undergoes operations including enrichment, processing and recycling in industrial facilities.

These operations are carried out at research and manufacturing sites such as those of the CEA and Areva and also at warehouses and waste storage sites such as those of the ANDRA. For these sites, Actemium offers specialized and comprehensive solutions in electricity, control systems, radioprotection, nuclear ventilation and physical protection. Omexom, another VINCI Energies brand, offers solutions for electricity production plants.
