I wonder how you’d transfer the heat without exposing the steep to radiation. I assume that would be bad anyways. I wish I paid attention more in physics, would love to know how such a system could be built.

Today we avoid radiating electric generation equipment by running two steam loops through a heat exchanger; one that interacts with the hot reactor and a second that spins the generators. Perhaps you could do similar with molten salt loops? Might be tough finding a material that would work as an exchanger at the required temperatures though.
Just using electricity is probably cheaper and easier; large power plants are crazy efficient already.
Thorium-based reactors famously are constrained by the lack of such material which would withstand the contact with hot molten salt, especially somewhat radioactive.
As anyone with a boat knows, salt water is insanely corrosive and gets into everything. Even large container ships have to be regularly serviced.
I can only what hot molten salt does to industrial processes.
