The US/US industry doesn't care about thorium reactors - the industry is only interested in the Integral Fast Reactor, burning uranium. At least IFR can burn nuclear waste, so it isn't a total loss, but we've already lost the race to develop them to Russia by continuously canceling our test reactors (Russia has two ~2000MW online and is building a full scale reactor from what I remember). The industry estimates that IFRs burning just nuclear wast can power the world for 1500 years. When the US (and British) nuclear industry talks about thorium, they ALWAYS mean in solid fuel reactors where it is an inferior fuel. When thorium advocates talk about thorium, they ALWAYS mean in a liquid fuel design based on the 1960s molten salt reactor experiment (MSRE).
The private industry, China, and France seem to be the only ones that like LFTR (liquid fluoride thorium reactor, the modern update to the MSRE, though France's is liquid lithium, a less toxic salt, so it should be LLTR, but they call it something else), so even if the US eventually goes that direction, we will be last to develop a reactor and buy that tech from other countries. The US is no longer an innovator in this area, we are a consumer, and the NRC and congress is at fault for most of it.
