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
