The "Chain-Building" Lessons from Europe's Fusion Supply Chain: An Industrial Paradigm Leap from "Building Devices" to "Nurturing Chains"

When examining the global race toward commercializing controlled nuclear fusion, external attention is often drawn to record-breaking plasma temperatures, confinement times, and device scales. However, as the industry gradually enters the deep waters of transitioning from physics experiments to engineering construction, what ultimately determines whether parties can cross the commercialization chasm is often no longer merely theoretical breakthroughs in the laboratory, but rather the thickness of the industrial supply chain hidden behind the spotlight. Recently, Europe's "Fusion for Energy" organization (F4E, Fusion for Energy) officially released the research report "Building Europe's Fusion Supply Chain: 2007–2026." This report, which systematically reviews nearly two decades of construction history, discloses that through more than €7 billion...

CNNC Atom High-Tech Sodium Iodide Capsules Supplied Directly to Macao for the First Time

Recently, sodium iodide [¹³¹I] capsules independently developed and produced by Atom High-Tech Co., Ltd., a subsidiary of China Isotope & Radiation Corporation under CNNC, successfully arrived at clinical frontlines in Macao, achieving the first stable supply of domestically produced sodium iodide [¹³¹I] capsules to Macao and completely filling the previous gap in Macao's lack of this clinical diagnostic and therapeutic service. It is understood that sodium iodide [¹³¹I] capsules are core radiopharmaceuticals widely used clinically for the diagnosis and treatment of thyroid diseases. Previously, Atom High-Tech had successfully achieved routine supply of short-half-life radiopharmaceuticals to Macao; the successful launch of this new product will strongly support Macao medical institutions in carrying out systematic radionuclide therapy and effectively reduce the burden of cross-border medical treatment on local patients.

Russia proposes optical laser monitoring method for spent nuclear fuel reprocessing

Recently, a research team from Sechenov University in Russia, together with the Proryv Project and the All-Russian Scientific Research Institute of Inorganic Materials (VNIINM), published latest results in the journal Applied Spectroscopy, proposing a non-contact optical method for continuous monitoring of the spent nuclear fuel reprocessing process. It is reported that in the liquid-liquid extraction process of spent nuclear fuel reprocessing, traditional laboratory analysis has problems such as long sampling time and increased risk of radioactive waste. The research team introduced Raman Spectroscopy to monitor the state of extractants such as tributyl phosphate in the organic phase, measuring a median error of about 1%; meanwhile, laser-induced breakdown spectroscopy (LIBS) was used to determine the concentration of metal elements in the aqueous phase, with an average error controlled at 4%–8%, achieving near-real-time synchronous monitoring of the two-phase streams.

IAEA Urges Kenya to Improve Radioactive Waste Policy

Recently, the International Atomic Energy Agency (IAEA) conducted a nine-day Artemis radioactive waste management assessment mission to Kenya and released its assessment findings in Nairobi, calling on Kenya to introduce a national radioactive waste management policy as soon as possible before introducing nuclear power and to strengthen the independence of its regulatory body. It is reported that this is the first Artemis assessment conducted by the IAEA in Africa, initiated at the request of the Kenyan government. The assessment team acknowledged Kenya's significant progress in radioactive waste management in recent years, while also recommending that Kenya develop a comprehensive policy framework covering nuclear energy, the nuclear fuel cycle and radioactive waste, and deepen regulatory...

Russian Floating Nuclear Power Plant Improves Air Quality in Arctic City

Recently, the Russian floating nuclear power plant Akademik Lomonosov released its latest environmental monitoring report. The report shows that since the nuclear power plant officially took over most of the heating load of Pevek in the Chukotka Autonomous Okrug in 2022, total pollutant emissions into the local atmosphere have plummeted from 11.64 tons to 2.281 tons, a reduction of nearly 80%. It is reported that Rosatom has established 11 automated radiation monitoring stations in Pevek and its surroundings to conduct comprehensive monitoring of air, water quality, soil, and waste. Monitoring results indicate that all environmental impact indicators are better than the established national standards, with average levels less than 10% of the maximum permissible...

Exploring the Frontier of Advanced Fusion Physics: Physical Mechanisms and Engineering Challenges of D–³He Secondary Neutron Suppression under the Synergy of Hot Tails and Spin Polarization

In the process of controlled nuclear fusion advancing from theoretical exploration to commercial validation, the choice of fuel pathway has always been the core variable determining the engineering feasibility and economics of a reactor. For a long time, the deuterium–helium-3 (D–³He) reaction has been regarded as an ideal "low-neutron" ultimate fusion scheme because its primary products are only charged particles (helium-4 and high-energy protons), it does not directly produce neutrons, and it possesses the potential for direct energy conversion. However, under the traditional thermal equilibrium plasma framework, D–³He is not a truly neutron-free fuel. In October 2026, the U.S. Princeton Plasma Physics Laboratory (PP...

Russia's Nuclear Icebreaker Leningrad Completes Anti-Icing System Installation

Recently, the Baltic Shipyard, a subsidiary of Russia's United Shipbuilding Corporation (ОСК), announced that it has successfully installed the anti-icing device turbo-compressor unit for the Leningrad, the sixth nuclear-powered icebreaker of Project 22220 currently under construction. It is reported that this domestically produced high-performance compressor can provide large-flow compressed air, forming an air-water curtain through underwater exhaust ports on the hull, thereby significantly reducing friction between the hull and ice and scouring away ice debris and accumulated snow. Combined with the 45 mm thick special steel used in the hull's ice belt, this anti-icing system can ensure that the nuclear-powered vessel maintains optimal navigation performance and structural safety when operating in the extreme cold latitudes of the Arctic.

Topological Fusion of Magnetic Mirror and Stellarator: How Fu Guoyong's Team's "Linked-Mirror" Deduces a New Engineering Pathway for Controlled Nuclear Fusion

After decades of fundamental theoretical exploration and engineering trial and error, global controlled nuclear fusion is accelerating into the deep waters of commercial validation. Faced with the engineering limits of the Tokamak approach under extreme parameters and the manufacturing complexity ceiling confronting traditional Stellarators, Chinese research teams are opening a new pathway that combines physical feasibility with engineering economy. Recently, the team led by Fu Guoyong, Professor at the School of Physics of Zhejiang University, Director of the Zhejiang University Fusion Theory and Simulation Center, and Founder of Jingjie Fusion Energy, officially released on the preprint website arXiv a research paper titled "A Novel Linked-Mirror Device for Fusion." Through three-dimensional numerical computation, the study obtained for the first time equilibrium solutions of the Linked-Mirror configuration under finite Beta (the ratio of plasma pressure to magnetic pressure) conditions. This breakthrough marks a decisive step for this technical pathway from a purely theoretical concept toward an engineering validation device.
