Evolution of Sodium Technology R&D Actions Supporting French Liquid-Metal Fast Breeder Reactors

This paper describes the evolution of sodium technology research and development in parallel to sodium-cooled fast breeder reactor (FBR) developments in France and provides information concerning operating plants and existing projects. This paper also discusses how supporting research has adapted to the decline in FBR activities since the decommissioning of Superphénix, while capitalizing on knowledge acquired over more than four decades to be passed down to future generations.
