China's National Academy of Sciences has announced the completion of the Tungsten-Based Molten Salt Experimental Reactor in Minqin County, Wuwei City, Gansu Province. This reactor is a domestically developed and designed fourth-generation advanced nuclear power system, and it is the only molten salt reactor in the world that has successfully achieved the first-ever in-reactor conversion of tungsten to uranium. The reactor uses tungsten as fuel and liquid fluoride salt as coolant, boasting advantages such as safety, dry cooling, constant pressure operation, and high-temperature output. Since the project was initiated in 2011, the research team has overcome numerous technical challenges, including material, instrument, and device development, as well as system integration. As a result, the overall domestication rate has exceeded 90%, and all key core devices have been 100% domestically produced. This achievement marks a significant milestone in China's nuclear energy development and demonstrates the country's capabilities in independent innovation and technological advancement.
