The way modern society is going, a LOT of power is going to be required along with an increase in the distribution network (EV's). Where it comes from, and how the "wires" are made are critical areas of research. Unless some novel research succeeds, distasteful decisions are going to be made to keep things going.
This boldly claims that molten salt reactors are safe, but my understanding is that these systems require carefully engineered coatings to function and that in practice every such system has leaked liquid sodium. The statement may be essentially true kind of like saying elevators are safe, but there is still room for risk analysis and expectation of occasional failures.
> In essence, a molten salt reactor [MSR] is a vessel that contains a hot liquid salt which a nuclear reaction takes place
The tl;dr on the page is missing a crucial word near "which", making the sentence nonsensical to me.
A molten salt reactor is, first and foremost, a distraction.
By the time any production molten-salt reactor design could get proved out and the first commercial one built, renewables + storage will be providing all our power for much less money than it ever could.
But we can waste a lot of $billions on it that could instead go to build out a hell of a lot of panels and wind turbines.
