reactor is regarded as better option now. It offers significantly simpler chemical processing of the fuel salt, easier neutronics and better fuel efficiency, and the design proposed by Flibe Energy makes replacing the graphite element every 5 years an easy task. The added expense is thus more than outweighted by cheaper and simpler online reprocessing chemistry.

I dont know if MIT studies considered non-classical reactors such as MSR, probably not if they reached such conclusion. LFTR would be an exception because its fuel is more abundant (thorium is 4x more abundant than uranium) and does not need any enrichment and fuel rod manufacture for use in a MSR. Its essentialy a simple chemical procedure - take natural Th and mix it with FLiBe salt = fuel salt ready for use.

SMR = small modular reactor. It is about the size of the reactor, which is less than 500 MW. The type of SMR can be anything from LWR to LFTR. SMR LFTR combines advantages of both SMRs and LFTRs.
