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.

Belarusian NPP safe operation period may be extended to 100 years, with first spent fuel to be shipped to Russia for reprocessing in 2034
Stanislav Levitsky, head of the Rosatom representative office in Belarus, stated on the "Economic Environment" program of Belarusian TV Channel One that Belarusian nuclear energy development is backed by comprehensive safety assurances. He emphasized that while nuclear facilities can indeed have serious consequences if mismanaged, under the existing risk control system and modern technological support at the Belarusian NPP, nuclear power can become a low-cost, stable, and safe energy source. Levitsky believes that amid intense competition in the energy sector, some irresponsible players may use information tactics to create anxiety and attempt to provoke panic among the public...

Japanese research team demonstrates ion wakefield acceleration for the first time, accelerating protons to a maximum of 60 MeV
Kyushu University, the National Institutes for Quantum Science and Technology (QST), and Osaka University recently announced jointly that the research team used high-intensity laser irradiation on a foam target to experimentally demonstrate the ion wakefield acceleration mechanism for the first time, providing a new experimental foundation for research on next-generation laser-driven ion accelerators. The results were published in *Communications Physics* on August 3, Japan time. According to the report, the research aims to reproduce physical processes similar to high-energy particle acceleration in space within a laboratory setting. Traditional high-energy accelerators typically require long acceleration tubes or large ring-shaped facilities, while the strong electric fields generated by plasma waves are considered promising for advancing accelerator miniaturization. However, compared with electrons, protons and ions...

First Concrete Pour (FCD) Successfully Completed for the Conventional Island of Unit 2 at Guangxi Bailong Nuclear Power Plant
At 10:06 on August 9, after 38 hours and 46 minutes of continuous effort, the First Concrete Pour (FCD) for the conventional island of Unit 2 at the SPIC Guangxi Bailong Nuclear Power Plant was successfully completed, marking the full commencement of the main construction phase for the conventional island. The basement floor slab of the conventional island of Unit 2 adopts an integral raft foundation, divided into 9 construction zones using the sequence method. This concrete pour covered Zone 1, starting at 19:20 on August 7, with a cumulative pour of 1,732 cubic meters of concrete, conducted safely and orderly throughout the process. Since July, Typhoon Maysak directly struck Fangchenggang, bringing successive storms, followed by days of high temperatures at the Bailong nuclear site, posing significant challenges to on-site construction. In response...

Jiangsu's First uLinac HalosTx Integrated Ring-Gantry CT Linac Enters Clinical Use
On August 7, the first uLinac HalosTx integrated ring-gantry CT linear accelerator in Jiangsu Province was officially put into clinical use at the Third Affiliated Hospital of Nanjing Medical University (Changzhou Second People's Hospital). The system integrates a diagnostic-grade CT scanner and a ring-gantry accelerator on a single platform, shifting regional tumor radiotherapy from the traditional step-by-step positioning approach to a same-platform real-time model. Radiotherapy is one of the important modalities for cancer treatment. In the conventional split-system radiotherapy workflow, patients typically need to be transported between the CT room and the treatment room, and treatment plans are mostly formulated based on static images acquired beforehand. In cases such as tumor regression or changes in patient weight, previous images may not fully reflect the actual condition on the day of treatment...

Laser spectroscopy reveals for the first time the precise nuclear shape of fermium-255, offering new clues in the search for superheavy elements
An international research team has, for the first time, precisely determined the nuclear structure of the actinide fermium-255, confirming that its nucleus exhibits a pronounced prolate deformation, similar to a rugby ball. The study, published in *Physical Review Letters*, was conducted in collaboration with 18 institutions, including Johannes Gutenberg University Mainz in Germany, the Helmholtz Institute Mainz, and the University of Gothenburg in Sweden. The findings not only correct several unreasonable nuclear property values in previous standard data tables but also provide crucial experimental validation for modern nuclear theory models. Fermium is a synthetic heavy element that does not exist in nature. Fermium-255 contains 100 protons and 155 neutrons, making its experimental production extremely challenging. The research team...

First Main Girder of Main Crane B Hoisted into Place in Conventional Island of Lufeng Nuclear Power Plant Unit 1
The first main girder of Main Crane B, the first main crane in the conventional island of Lufeng Nuclear Power Plant Unit 1, began lifting at 8:45 on August 7, 2026, and was positioned at 11:31. This marks the official commencement of main crane hoisting work in Conventional Island Unit 1; all hoisting work for Main Cranes A/B is expected to be completed by August 10. The main building of Conventional Island Unit 1 of Lufeng Nuclear Power Plant Unit 1 is equipped with two main cranes, designated Main Crane A and Main Crane B, arranged on the same level with a lifting capacity of 240t/40t each. These are critical lifting equipment for the nuclear power plant, primarily used during the construction phase for hoisting major conventional island equipment such as steam turbines, generators, condensers, moisture separator reheaters, and condensate pumps, as well as other installation work including piping and valves. During the operational phase of the nuclear power plant, they are used for maintenance of the turbine-generator unit and other in-plant items during overhaul periods.

German team achieves first separation of tritium-containing hydrogen isotope mixtures using silver-exchanged zeolites
A team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and partners recently demonstrated a new method for separating hydrogen isotopes using silver-containing zeolites, successfully separating hydrogen isotope mixtures containing radioactive tritium through a porous solid material for the first time. The research findings were published in Nature Communications. Future fusion power plants will require not only high-temperature plasma and strong magnetic fields during operation, but also a stable fuel cycle system for recovering, separating, and reusing deuterium and tritium. Inside a fusion reactor, deuterium and tritium participate in reactions and release energy, but the fuel is not completely consumed, and the residual gas may also contain ordinary hydrogen (protium), forming a mixture of protium, deuterium, and tritium...

U.S. NRC to Debut Modernized Hearing Process in Advanced Reactor Licensing Review for the First Time
The U.S. Nuclear Regulatory Commission (NRC) will hold a public hearing on August 13 in Oak Ridge, Tennessee, to consider the Tennessee Valley Authority's (TVA) application to build a small modular reactor at the Clinch River site. This will mark the first time the NRC applies its modernized mandatory hearing framework in an advanced reactor licensing review. According to the NRC, the new hearing process is designed to give the public earlier insight into the agency's review of the project's safety and environmental impacts, while improving the transparency, predictability, and efficiency of licensing reviews. As part of its licensing modernization efforts, the NRC currently aims to complete construction permit-related decisions within 18 months. TVA plans to...
