Has anyone ever read much about LAMPRE?
(The reactor with the molten Plutonium-Iron eutectic as the fuel?)

Molten salts have problems of corrosion and operational feasibility will take a long time.
Lead presents erosion problems though it is used in Russia to a large extent
Sodium is benign to metals but has violent reactions with water and air.

The next generation of reactors could
a. Burn the used LWR fuel in fast reactors, or
b. Use a thorium-RG plutonium fuel in LWR/PHWRs.
A fast MSR should best have the liquid fuel confined to the core and heat transported by clean coolants. Same goes for LMFR.
The LWR/PHWR could use thorium fuel with long burn up and irradiate more thorium in the blanket to create stocks of U-233 thorium breeders could be possible with U-233 fissile.
