Promising technologies are developing for the nuclear power
plant, reprocessing, and fuel fabrication of the FR cycle. FRcandidate concepts consisting of a combination of thesetechnologies are proposed.

Six FR cycle candidate concepts which have combined the FR cycle fieldsof reactor and fuel cycles.
