In a groundbreaking development, China has made history by running the first thorium molten salt reactor in the Gobi Desert's sands of Gansu Province. This achievement, which involved reloading fuel without powering down the reactor, represents a significant leap in nuclear technology, overcoming challenges that had persisted for over six decades. The revival of molten salt reactors, once abandoned by the U.S. in the 1960s, has now become China's nuclear frontier, blending declassified American research with Chinese expertise and determination. Operating at temperatures exceeding 700°C with molten fluoride salts, the reactor ensures safety by eliminating high-pressure systems, thus mitigating the risk of meltdowns through passive safety mechanisms. Furthermore, thorium reactors offer a solution to the pressing issue of radioactive waste, producing less plutonium and generating waste that decays faster than conventional nuclear reactors. One of the standout features of thorium technology is its potential to pave the way for a hydrogen future. The reactor's high temperatures enable the viability of thermochemical hydrogen production, offering a pathway towards a green hydrogen economy and the utilization of thorium-based energy in various sectors, including shipping. While this breakthrough signals a shift towards sustainable nuclear power, challenges remain, particularly in the realm of materials science. Molten salt reactors pose a unique challenge as the salts can be corrosive to metals, requiring the development of materials like Hastelloy-N that can withstand radiation, heat, and chemical corrosion over extended periods. With the U.S. stepping back from nuclear innovation, China has emerged as a frontrunner in the field, spearheading advancements in thorium technology and positioning itself as a leader in clean, non-military nuclear energy. Xu Hongjie, the project chief, emphasizes China's role as a successor in nuclear innovation, underlining the country's commitment to shaping the future of energy production.
