The international standard ISO 19991:2026 “Fusion Technology - Experimental Magnetically Restrained Fusion Facility - Ultrasonic Molecular Beam Injection and Feeding Technology for Fusion Devices”, developed by China, was officially released on August 10, local time. Earlier, during the final voting process, all 12 countries, including France, Germany, and Russia, voted in favor. This is the first ISO international standard in the field of fusion feeding, and the second ISO international standard for fusion developed by CNNC's Southwest Institute of Physics for Nuclear Industry. Ultrasonic molecular beam injection and dosing technology is a key fuel supply technology for controlled nuclear fusion devices. This technology is China's original advanced fusion feeding technology. It forms high-speed, targeted molecular beams through gas adiabatic expansion. It has the characteristics of high speed, strong directionality, high feeding efficiency, and low particle recycling. It can significantly improve the fuel control capacity of fusion devices, and has been applied in more than ten magnetically-constrained fusion experimental devices at home and abroad.
