China has world’s first operational thorium nuclear reactor thanks to ‘strategic stamina’ (www.scmp.com)

It marks the first long-term, stable operation of the technology, putting China at the forefront of a global race to harness thorium – considered a safer and more abundant alternative to uranium – for nuclear power.

The experimental reactor, located in the Gobi Desert in China’s west, uses molten salt as the fuel carrier and coolant, and thorium – a radioactive element abundant in the Earth’s crust – as the fuel source. The reactor is reportedly designed to sustainably generate 2 megawatts of thermal power.

The problems however are not unsolvable

Meaning that they are not solved. I don't want the grid in my country powered by tech that is not proven safe, reliable, and with a good ROI.

Much much safer than the uranium we currently use

Potentially. It's not a technology proven in large-scale operational use.

If they make it work at scale, China becomes the first country in the world that essentially has unlimited energy.

If my aunt were to have bollocks, she'd be my uncle.

The "if" is doing a lot of heavy lifting in your sentence. And "unlimited energy" is a gross exaggeration. There are still downstream costs and environmental damage.

It's a matter of implementation versus invention.

If I asked you to build a hundred story skyscraper, that would be difficult, but we already have all of the technical components. All the component problems are already solved- we know how to make high quality steel, we know how to design the frame of such a building, we know how to anchor it into the ground, etc. You just need to put those technologies together in a functional design.

If I asked you to build me a spacecraft that goes faster than light, you couldn't, because that sort of propulsion system has never been built. And while we have theories on how one might build it, we don't currently have the capability to build any of those theoretical drive systems even as test articles (mainly because they need things in space larger than we have the capability to launch or will have the capability to launch anytime soon).

But if I asked you to build a thorium reactor, all of the component problems have been solved. We have a lot of coatings that resist corrosion, and so making valves and pipes out of them (and more importantly, designing the system of valves and pipes) takes work but we know how to do it. We understand how to make and process thorium fuel, even if we don't have much experience doing it.

As for your grid, I don't want my grade either powered by text that isn't safe reliable and productive, but the fact is we don't have that right now. A lot of power still comes from coal and similar shitty sources. So I will absolutely take less shitty.

Yeah I use the word if a lot, but that has a level of probability associated with it. I can say if we figure out a way to generate power from magic pixie dust tomorrow our energy problems will be solved but there's no probability of that. Here there is a technology that has been known to work since the 1900s, that we have built research reactors on, and that is now being actively developed. The "if" here has a high degree of probability.
