Ask HN: What happened to the Thorium reactor hype?

There are a lot of technical problems related to online processing of the fuel, the reactivity of salts at high temperatures with metals, etc.

It's a matter of research and development, it can be done, if we devote enough resources to get across the finish line.

Wasn't that right around the time of Fukushima? https://en.wikipedia.org/wiki/Fukushima_nuclear_disaster

It never made much sense. Thorium wasn't solving the problem (cost) that was holding back nuclear energy.
