ITER Tokamak Advances Assembly in France, Fusion Experiment Targets 150 Million Degree Celsius Plasma

The ITER tokamak being assembled in southern France is one of the most closely watched large-scale experimental devices in global nuclear fusion research. The machine weighs approximately 23,000 tonnes in total and adopts a donut-shaped toroidal structure, using strong magnetic fields to confine high-temperature plasma, with the goal of replicating on Earth the conditions for fusion reactions that occur inside stars. Its plasma volume is approximately 830 cubic meters, far exceeding previous tokamak devices, and it is therefore expected to validate the key physics and engineering technologies required for future commercial fusion reactors. ITER adopts the toroidal tokamak structure because charged particles can move along toroidal paths under strong magnetic fields, thereby minimizing direct contact with the device's inner walls...

UK's Materials Detritiation Facility at Culham Resumes Operations to Support JET Fusion Decommissioning Materials Research

The UK Atomic Energy Authority recently announced that the Materials Detritiation Facility (MDF) at Culham has resumed operations following a 12-month engineering shutdown and upgrade. Experimental data produced by the facility has already been used to support research related to the removal of materials from the Joint European Torus (JET) device, providing a basis for waste management strategies under the JET Decommissioning and Repurposing (JDR) project. Over three years of plasma operations, deuterium-tritium (DT) experiments conducted at JET have left residual amounts of tritium in the tokamak's walls and internal components. This phenomenon is associated with tritium's tendency to enter materials under high-power fusion operating conditions. For JET decommissioning work, accurately determining the tritium...

Two IPP studies reveal edge turbulence mechanisms in fusion plasmas from first principles

On August 10, 2026, two research teams at the Max Planck Institute for Plasma Physics (IPP) independently published findings that, for the first time, explain key phenomena in the extremely thin edge layer of fusion plasmas starting from fundamental physics equations. Both papers were published in Physical Review Letters, with one highlighted as an editor's suggestion. For stable operation of a fusion power plant, two requirements must be met simultaneously: on the one hand, the plasma at temperatures of around 100 million degrees Celsius must be effectively confined to achieve fusion ignition conditions; on the other hand, the generated heat must be distributed over a sufficiently large area to prevent damage to the device walls from excessive local heat loads. Whether this conflict can be resolved depends largely on a region only a few centimeters thick at the plasma edge.
