I seriously doubt there’s any useful overlap between nuclear for space and for terrestrial power generation. Even if there were, we’ve spent close to a century proving that nuclear is expensive and time consuming to run and thorium’s theoretical advantages re mostly only in comparison to existing nuclear technology. Research is always good, but that really looks like a dead end, especially in comparison to something that is cheap and ubiquitous, and entirely ready, just needs scale out. Even that is already happening
In some countries nuclear is cheap and ubiquitous. The key is simple standardization.
In France for instance, nuclear accounts for about 70% of their power. They operate 57 nuclear reactors, all of which are one of 4 reactor designs. By having standardized designs these reactors are cheaper to maintain, parts and equipment are more available. The engineers that run the facilities are more familiar with every aspect of the plant, operating procedures are better understood. It's easier to find qualified engineers and technicians. Accidents are uncommon (I believe they've never had any kind of major accident).
The price French households pay for power is comparable to what we pay in the US and they generate significantly less CO2 per capita. They also have less reliance on oil states.
We could have that too if we were motivated to make it happen.
And trains!
