Unanimously Approved! China's First ISO International Standard in the Field of Fusion Fueling Officially Released

On August 10 local time, the international standard ISO 19991:2026, "Fusion Technology — Experimental Magnetic Confinement Fusion Facilities — Ultrasonic Molecular Beam Injection Fueling Technology for Fusion Devices," formulated by China, was officially released. Earlier, during the final voting process, all 12 countries, including France, Germany, and Russia, cast affirmative votes. This is the first ISO international standard in the field of fusion fueling and the second ISO international standard in the fusion field led by the Southwestern Institute of Physics (SWIP) under the China National Nuclear Corporation (CNNC). Ultrasonic molecular beam injection fueling technology is a key fuel supply technology for controlled nuclear fusion devices. This technology, an advanced fusion fueling technology originally developed by China, forms high-speed, directional molecular beams through adiabatic gas expansion. It features high speed, strong directionality, relatively high fueling efficiency, and low particle recycling, significantly enhancing the fuel control capability of fusion devices. It has been applied to more than ten magnetic confinement fusion experimental devices both domestically and internationally.

Vietnam to Develop 88 National Standards and 6 National Regulations Supporting Nuclear Power and Atomic Energy Applications from 2026–2030

Vietnam will develop standards and regulations for nuclear power development to support the construction of future nuclear power plants and advancements in atomic energy applications. To align with this goal, the country plans to establish 88 national standards and 6 national regulations during the period from 2026 to 2030, covering key areas such as nuclear power plant safety, radiation safety, environmental monitoring, and related equipment. These standards will reference existing practical experience from the International Atomic Energy Agency (IAEA), the International Organization for Standardization (ISO), and the International Electrotechnical Commission (IEC), and will be periodically reviewed and adjusted based on project progress and actual management needs. The development of these standards is carried out in four phases, each with clearly defined focal objectives...

National Standard Compiled by CNNC Mining and Metallurgy Technology Successfully Released

Recently, the national standard "Methods of Analysis of Uranium Ore Concentrate - Part 1: Determination of Uranium - Ferrous Sulfate Reduction - Potassium Dichromate Titration Method" (GB/T 11848.1-2026), compiled by CNNC Mining and Metallurgy Technology Group Co., Ltd. (Beijing Research Institute of Chemical Engineering and Metallurgy, CNNC), was officially released. With this, all 15 national standard methods for "Methods of Analysis of Uranium Ore Concentrate" (GB/T 11848.2-11848.16, implemented in May 2026) led by our company have been fully released. Uranium ore concentrate is an important intermediate product in the nuclear fuel cycle, with its core value lying in the uranium it contains. The determination of uranium content is a crucial link throughout the entire industrial chain from ore to nuclear fuel. This is not merely a simple compositional analysis, but a core step in ensuring economic benefits, product compliance, process safety, and conformity with international regulations. The control of impurity elements plays an important role in the uranium purification and conversion process. The determination of impurity elements is primarily aimed at meeting product control and quality assurance requirements, ensuring downstream process safety, and supporting nuclear safeguards and forensic traceability. The new series of analytical methods is better adapted to modern production processes and detection techniques.
