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.AdvertisementIt 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.AdvertisementDuring the April 8 meeting, Xu said China “now leads the global frontier”, according to Guangming Daily.
