As far as I know there is, after 70 years of research in many nations, not a single industrial satisfactorily working fast-breeder reactor. Is there one? https://en.wikipedia.org/wiki/Breeder_reactor#Development_an...

The most advanced one is Russia's BN-800 (now burning 60% MOX). Its planned big brother was cancelled "In 2015, after several minor delays, problems at the recently completed BN-800 indicated a redesign was needed. Construction of the BN-1200 was put on "indefinite hold", and Rosenergoatom has stated that no decision to continue will be made before 2019." https://en.wikipedia.org/wiki/BN-1200_reactor

This is not due to a lack of interest or funding because Russia launched a new project towards another architecture and builds a small reactor: https://en.wikipedia.org/wiki/BREST_(reactor)
