ITER magnet energized to 34,000 amperes: why must a 330-tonne coil be verified starting from half rated current?

On October 30, at the International Thermonuclear Experimental Reactor (ITER) construction site in southern France, a 330-tonne D-shaped coil was transferred from the cryogenic test facility to a transport frame. ITER Organization announced on November 2 that this No. 17 toroidal field coil had been energized to 34,000 amperes at approximately 4 kelvin, reaching half of its rated operating current. The focus of the test was to compare the deformation measured under electromagnetic loads with structural models. For a magnet that will eventually be installed together with the vacuum vessel into a confined space, millimetre-scale shape changes, local heating at electrical joints and identification of quench signals all warrant separate verification before final assembly.

Floating Molten Salt Reactor Approaches Licensing Readiness: What New Issues Must Be Addressed When Putting Nuclear Power on a Barge

Coastal industrial parks need stable power, but onshore land, cooling conditions, and construction resources may not be easy to coordinate. Placing power generation facilities on floating platforms and having them centrally manufactured by shipyards has therefore become a deployment approach explored by some nuclear companies. It may change the construction location, but it will not detach the reactor from site, regulatory, and long-term operational responsibilities. Information published on November 3 shows that Denmark's Saltfoss is preparing to engage in pre-application communication with the U.S. Nuclear Regulatory Commission and plans to submit a regulatory communication plan in the first quarter of 2027. The company hopes to establish a licensing pathway for offshore molten salt reactor platforms. What has been disclosed so far is preparatory work and corporate goals, and should not be understood as having obtained...

Recycled chloride salt fuel prepares to enter research reactor: Can spent fuel become a resource, and what data must be obtained first?

Turning nuclear material into another kind of fuel. Idaho National Laboratory (INL) announced on November 2 that it will lead the IMPACT project to fabricate and test chloride salt fuel containing recycled transuranic elements. The project has received $7 million in support from the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) and plans to use nuclear materials already available at the laboratory to complete fabrication and property testing, and to conduct irradiation in the Advanced Test Reactor (ATR). This research advances the improvement of spent fuel utilization to a specific question: after recovered materials form new fuel, how exactly do they change in the reactor environment? Moltex participates in modeling and design-related work.

Startup "Marathon Fusion" Announces Transmutation of Mercury into Gold Using Thermonuclear Fusion Neutrons

Recently, San Francisco-based startup Marathon Fusion announced that it has successfully used high-energy neutrons produced by deuterium-tritium (D-T) thermonuclear fusion reactions to transmute the element mercury into gold, claiming that its yield reached ten times the previously recorded level at CERN. It is reported that the technology is based on high-energy neutrons released by D-T fusion reactions striking mercury-198 nuclei, stripping one neutron to convert them into the radioactive isotope mercury-197, which subsequently decays to ultimately form gold-197, the only stable isotope of gold. Marathon Fusion published gamma-ray spectroscopy as characteristic evidence for the presence of mercury-197; however, the specific mass of gold produced remains at...

China's Highest-Latitude High-Speed Railway, the Harbin-Yichun High-Speed Railway, Puts "Robot Doctor" into Service, Boosting Hollow Axle Flaw Detection Efficiency by 30%

China's highest-latitude high-speed railway, the Harbin-Yichun High-Speed Railway, has officially opened for operation. Faced with the dual challenges of opening a new line under extreme cold climate conditions and the high-intensity operation of EMUs, flaw detection of hollow axles—key load-bearing components of the car body—has become a core link in ensuring the safe and smooth operation of trains. Previously, flaw detection operations for EMU hollow axles mainly relied on manual operation, which not only imposed high labor intensity on maintenance personnel but also placed extremely high demands on detection accuracy and standardization. In response to the technical requirements under severe cold environments and the efficiency pain points of traditional manual maintenance, the Harbin EMU Depot of China Railway Harbin Group Co., Ltd., together with a scientific research team, successfully developed an intelligent mobile hollow axle ultrasonic flaw detector, which has already been put into trial use in EMU trial operations and routine maintenance.
