Chinese scientists have achieved a milestone in clean energy technology by successfully adding fresh fuel to an operational thorium molten salt reactor, according to state media reports.

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 development was announced by the project’s chief scientist, Xu Hongjie, during a closed-door meeting at the Chinese Academy of Sciences on April 8, the official Guangming Daily reported on Friday.

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.

Some experts see the technology as the next energy revolution and claim that just one thorium-rich mine in Inner Mongolia could – theoretically – meet China’s energy needs for tens of thousands of years, while producing minimal radioactive waste.

A much bigger thorium molten salt reactor is already being built in China and is slated to achieve criticality by 2030. That research reactor is designed to produce 10 megawatts of electricity.

China’s state-owned shipbuilding industry has also unveiled a design for thorium-powered container ships that could potentially achieve emission-free maritime transport.

Meanwhile, US efforts to revive the development of a molten salt reactor remain on paper, despite bipartisan congressional support and Department of Energy initiatives.

I read that and thought "damn that's such a long time away" before realizing 2030 is in just 5 years now

5 years is a long time

China really is living in the future. Building new space stations, high speed rail and ever cheaper, cleaner energy.

Meanwhile , a single US state is approaching its third decade of trying to build a single line of high speed rail, and our federal politics consist of watching our most ancient boomers build a Gestapo while they are actively dying of old age.

This is HUGE!
