As far as I know, there are no (public) models on Th reactors. The most advanced is an analytic simulation (without CFD) from a Chinese nuclear engineering lab, but nobody has a real clue about the precise input variables anyway, therefore no MC is even in sight, as of today. But marketing is well advanced. And as the Japanese say, assuming we do have a functionally correct model and a Th reactor design (or designs, since there are several configurations), that still doesn't say anything about the economic aspect (I do not mean the old economic model, where the byproduct of plutonium factories were sold as energy).
