Too bad we do not know which exactly thorium salt mixes they are using, what the materials facing the molten salt at high neutron fluxes are and how they fare long term, whether they use on-site constant or batched fuel reprocessing, whether they kickstarted the reactor with enrichened uranium or reactor-grade plutonium waste and other such questions.
US experiments were broken off because of materials corrosion problem.
i think that lack of willingness to handle fresh fission products has a part in this, in normal reactor you can just do nothing and win (bulk of most dangerous isotopes decays completely within 5y, not possible to do this with MSR)
I think maybe also the fact that nuclear fusion is definitely frfr only a few years away from being viable, no cap, has contributed to a lack of fission research, too.
SMRs too
