Molten Salt Reactors already lost to the Liquid Metal Reactors. Latter are cheaper, more reliable and don't need specific materials for cooling system with all advantages of Molten Salt Reactors. Also, use of liquid metal as coolant allow building of reliable fast neutron reactors, that are necessary for closing fuel cycle of NPPs.

There are operational LMRs in many countries already, Most powerful was build in France with more than 1.2GW electric power, but it was a prototype and reached 95% of power in 1996 and was decommisioned in 1997.

Currentrly, fast neutron LMRs works in Russia (commercial), China and India (prototypes).

LMR reactor allow to build very small reactors, Pratt&Wittney examined it as possible power unit of never implemented nuclear plane.

LMRs heavily used on icebreakers and submarines.

Most popular coolants are sodium and lead or lead-bismuth alloy.
