China Successfully Operates World's First Thorium Molten Salt Reactor

An experimental Chinese nuclear plant reportedly just crossed a historic threshold, successfully operating the world’s first thorium-based molten salt reactor (TMSR). The Chinese Academy of Sciences’ Shanghai Institute of Applied Physics has broken a major scientific barrier by successfully converting thorium to uranium in a historic first.

The Hong Kong-based South China Morning Post reports that the breakthrough, which took place at an experimental reactor out in the Gobi Desert, is “poised to reshape the future of clean sustainable nuclear energy.”

The process works by using a “precise sequence of nuclear reactions” in which naturally occurring thorium-232 absorbs a neutron, becoming thorium-233. Through a decay process, that isotope breaks down into protactinium-233 and then finally into uranium-233, a potent form of nuclear fuel that can sustain chain reactions for nuclear fission.

While this bre akthrough was just publicized this month by a report by Science and Technology Daily, the TMSR has apparently been operational for years. Li Qingnuan, Communist Party secretary and deputy director at the Shanghai Institute of Applied Physics, told the outlet that “since achieving first criticality on October 11, 2023, the thorium molten salt reactor has been steadily generating heat through nuclear fission”.

If the reports are true,
