Fluoride salts are good for fissile uranium + fertile thorium. If you want to work with a plutonium/uranium 238 cycle then chloride salts are a better choice. Plutonium doesn't dissolve very well in fluorides.
Molten chloride reactors can have performance characteristics right out of science fiction, it seems possible for such a reactor to not only breed more fuel but to destroy the long-lived (500 year) fission products such as cesium and strontium.
It never gets upvoted on HN when I link it but I've been following MSRs for a while and even spoke at the first thorium energy conference and I've been watching people's thoughts about designs evolve and this one

is well ahead of the others.
