Well..this is new! Long considered to be the next big step in atomic power generation..this is a game-changer--and to think they did by taking old US plans and using them as their basis!



Chinese scientists have completed a major breakthrough in clean energy by reloading fresh fuel into a working thorium molten salt reactor.

They did this while the reactor continued running, marking a significant step forward in the global push to use thorium as a safer and more abundant alternative to uranium in nuclear power.

The milestone was revealed at a closed-door meeting on April 8 at the Chinese Academy of Sciences (CAS), where project chief scientist Xu Hongjie shared the news with colleagues.

In the 1960s, American researchers built and tested early molten salt reactors, but the United States eventually shelved the program in favor of uranium-based technology. “The US left its research publicly available, waiting for the right successor,” Xu said. “We were that successor.”

Xu and his team at the CAS Shanghai Institute of Applied Physics studied declassified American documents, recreated the old experiments, and then developed the technology further. “We mastered every technique in the literature – then pushed further,” he said.
The team’s efforts ramped up quickly. Construction on the current reactor began in 2018, and the team grew from a few dozen researchers to more than 400.

Many skipped holidays and stayed on-site for most of the year. The reactor reached criticality in October 2023, achieved full-power operation by June 2024, and successfully completed in-operation thorium reloading just four months later.

The country is already building a much larger thorium molten salt reactor that is scheduled to reach criticality by 2030 and generate 10 megawatts of electricity.

Meanwhile, China’s shipbuilding industry has also unveiled blueprints for thorium-powered container ships that could enable zero-emission sea transport.

Its ik. The MAGA admn is cutting research.

Now I understand why you are so excited. Once again, China exploits technology America created.

Nope.
Excited because this is a game-changer. The fossil fuel folk won't like it..so the US will lag behind..yet again.
But for the rest of the world..it is a clear and clean answer to their power needs~

And it took your buddies the chinese to make the world realize this with 70 year old U.S. technology?
 
And I am just going to sit back and laugh when people start to comprehend what "Molten Salts" actually are.

And how insignificant 10 MW of power production actually is.

Wouldn’t even drive a submarine.

The importance of this is in the 'proof of concept'.
It will scale up..and up.
 
Hush, let the chi-com lovers live in their fantasy world.

Well, this is common in a lot of people who really do not understand science. They only think they do because of what some YT video or "journalist" tells them.

Such as "molten salt". Most people hear that, and think it is just table salt. But it is not, far from it. It is the chemical definition of "salt", and is quite toxic. Sodium fluroacetate, sodium nitrate, potassium chloride, and others. Whenever I hear "molten salt", I immediately think "high temperature toxic chemicals", because that is exactly what it is.

Nope. The fossil fuel folk would love
Clean nuclear. It's been usually the alternative energy guys who won't consider nuclear

Chemically ... salts are the lowest level of energy ... we'd use the one with the best heat capacity and high boiling point ... there's plenty of non-toxic options available ... the problem with water is it flashes into steam if the cooling pumps aren't kept running after a SCRAM ... like at the Fukushima plants, only one got their pumps running again ... with salt we don't have that problem, the boiling point is higher than the nuclear core ...

BTW: Potassium chloride is FDA-approved as human food ... just saying ...

So is Sodium Chloride. Does not mean you want multiple tons of it in a hot liquid form dumped on the landscape.

That would be as large of an ecological disaster as an oil spill. Possibly even larger as salts would be much more likely to enter the aquifer, spread downstream, and soak deeper into the ground. Oil is a very viscous fluid and actually resists flowing or being absorbed (which is why it makes an excellent lubricant). A property that molten salts do not share, they love being absorbed in water. And once absorbed, are pretty much impossible to get out of the water.

With oil and water, it just sits on top and you just have to absorb it off of the water. I believe that a 10,000 gallon oil spill would be far less destructive to the environment than a 5,000 gallon molten salt spill.

You want to use flammable liquids as a nuclear reactor coolant ??? ... 10,000 gallons of gasoline at 400ºC detonates when mixed with air ... yeesh ...

5,000 gallons is less than 20 cubic meters ... for comparison, the Connecticut River averages better than 500 cubic meters a second ... and the salt would be LESS TOXIC than the PCPs and other pollutants in that river right now ... and again, chemically these salts are generally non-reactive in nature ...

Here's a partial list of the other things released into the environment ... and you're worried about a little bit of salt ... wow ...
