I have a tremendous love for the fast breeder reactors (particularly Superphénix); that we had that technology so long ago astounds me. However, I recognise that they are technically challenging.

From a modern, pragmatic point of view, I'm very partial to SMRs and AMRs (advanced modular reactors). They are also easier to implement on non-technical grounds (e.g. site permissions).

France has basically abandoned their fast breeder effort. They defunded the next fast reactor.
