中國科學家利用美國舊有的研究成果和數十年的耐心,將釷基核能帶入現實生活。
中國剛剛在核能領域邁出了一大步,重啟了釷基熔鹽反應器——無需停堆換料。這項古老的技術幾十年前由美國首次嘗試,後來被放棄。它使用熔鹽安全地容納液態釷燃料。這意味著它不會像傳統反應器那樣熔化,產生的廢物也更少。
原型機自2024年中期在戈壁沙漠運行,可為約2,000戶家庭供電。釷比鈾更容易找到,也更常見,使其成為未來一種很有前景的能源。中國甚至發現了足夠全國使用數萬年的釷。
沒有人確切知道他們是如何解決阻礙過去努力的棘手問題的,但緩慢而穩定的努力最終獲得了回報。這可能會改變全球清潔核能的格局,並有助於減少碳排放。
Chinese scientists bring thorium nuclear power to life using old US research and decades of patience.
China just made a big move in nuclear energy by restarting thorium-based molten salt reactors—without needing to shut them down to refuel. This old tech, first tried and then dropped by the U.S. decades ago, uses molten salt to safely hold liquid thorium fuel. That means it can’t melt down like traditional reactors and creates way less waste.
The prototype, running since mid-2024 in the Gobi Desert, can power about 2,000 homes. Thorium is easier to find and way more common than uranium, making it a promising energy source for the future. China even found enough thorium to power the country for tens of thousands of years.
No one’s sure exactly how they solved the tricky problems that stopped past efforts, but slow, steady work paid off. This could change the game for clean nuclear energy worldwide and help cut carbon emissions.
