Another company called Flibe is said to be working around the current regulatory restraints by designing thorium reactors for US military bases for which no regulator restraints apply.
The US DOE is currently funding a Canadian thorium reactor company which also is not under current US regulatory constraints.
The US Nuclear Regulatory Commission NRC doesn’t have any rules yet that apply to the molton salt designs. All of their regulations were designed for light water reactors.
I think there will be some movement in this area in the next couple years.
Whether its fast enough to get the 4-5 US companies involved in 4th generation msr tech into first place in the molten salt reactor race remains to be seen.
That is a positive outlook...it would be nice to see.
