The document summarizes the organization and activities of the Nuclear Energy Division (DEN) of the French Alternative Energies and Atomic Energy Commission (CEA). The DEN is organized into strategic, functional, and operational divisions overseeing nuclear research reactors, fuel cycle facilities, dismantling projects, and simulation activities. Its four main centers are located at Saclay, Cadarache, Marcoule, and Fontenay-aux-Roses. The DEN works on optimizing current nuclear technology, developing 4th generation reactors, and cleaning up and dismantling end-of-life nuclear sites, with the goals of supporting the nuclear industry and developing future energy solutions.

6. The choice of France: sodium-cooled fast reactor (SFR) technology
Technology assets:
 Plutonium multi-recycling
 Preserving natural uranium resources
 Support for high-level waste management
This technology has already acquired a certain level of maturity but now remains to be
improved for the 4th Generation: safety, savings, availability, in-service inspection &
repair
Strong guarantee: the technology can be ready by 2040
Close-knit coordination with French and foreign industrial partners around the Astrid SFR
project
Technology of international standing
