First Experimental Result Published from the High-Intensity Heavy-Ion Accelerator Facility

Recently, the research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with collaborators, successfully produced and identified the rare isotope hafnium-153 using the High-Intensity Heavy-Ion Accelerator Facility (HIAF). This is the first physics result obtained during the commissioning of HIAF, demonstrating that China's new-generation high-intensity heavy-ion research facility is capable of exploring unknown nuclides and expanding the nuclear chart. It marks the official commencement of HIAF's scientific discovery journey. The result was published as a short communication in *Science Bulletin*. Figure: Position of hafnium-153 on the nuclear chart; the blue line indicates the boundary of known nuclides. Image | Hu Houyu, Li Hongfu. Atomic nuclei are composed of protons and neutrons, and different combinations of proton and neutron numbers form the diverse world of nuclides. Exploring unknown nuclides and investigating the boundaries of nuclear existence are important frontiers in nuclear physics. Hafnium-153 is located in the neutron-deficient heavy-mass region and is an important subject for studying the evolution of nuclear structure and the limits of nuclear stability. It had not been reported prior to this experiment. The discovery and precise measurement of this nuclide will help test nuclear theory models and deepen our understanding of nuclear structure regularities.

Danube at Record Low, Hungary's Paks Nuclear Plant Faces First Full Shutdown in 44 Years

On August 2, Hungarian authorities stated that the Paks Nuclear Power Plant may halt electricity generation due to the Danube River dropping to a historic low. This is the country's only nuclear power plant, with an installed capacity of approximately 2 gigawatts, generating nearly half of Hungary's total electricity output. The Paks Nuclear Power Plant draws water from the Danube for cooling. Due to persistent high temperatures and insufficient rainfall, the Danube's water level has been continuously declining recently. Hungarian water authorities predict that the river, which flows from Germany to the Black Sea, will see further drops in water levels in the coming days. As of 18:37 GMT on August 2, the Paks Nuclear Power Plant's output was only slightly above 10% of its installed capacity. Péter M...

Additively Manufactured CrMoTaTiV Refractory Alloy Demonstrates Excellent Radiation Resistance

A materials study released on July 31 shows that a research team used laser powder directed energy deposition (LP-DED) technology to fabricate a novel Cr₁₀Mo₂₅Ta₂₅Ti₁₅V₂₅ refractory complex concentrated alloy and systematically evaluated its structural stability and mechanical properties under irradiation environments. The study targets the demand for high-temperature, high-irradiation structural materials in next-generation nuclear fission and fusion devices. In the study, samples were subjected to 3.5 MeV Fe²⁺ ion irradiation at the Ion Beam Materials Laboratory of Los Alamos National Laboratory in the United States, at irradiation temperatures of room temperature and 650°C, with local doses reaching approximately 1.8, 6, and 18 dpa. Microstructural analysis...

Kangbuk Samsung Hospital in South Korea Validates Precision of New-Generation Surface-Guided Radiation Therapy System

The research team from the Department of Radiation Oncology at Kangbuk Samsung Hospital in South Korea announced on July 31 that they have completed validation of the geometric accuracy and respiratory tracking performance of a new-generation surface-guided radiation therapy system. The research findings have been published in the latest issue of the international academic journal *Radiation Physics and Chemistry*. In breast cancer radiotherapy, the deep inspiration breath-hold technique is commonly used in clinical practice to reduce radiation exposure to the heart and lungs. Traditional procedures typically require tattoo marks or drawn guide lines on the patient's skin surface, along with wearing sensors to monitor respiratory motion, which somewhat compromises treatment convenience and patient comfort. The new-generation surface-guided radiation therapy system validated in this study utilizes 3D stereoscopic cameras and thermal imaging technology...

Japan's Nuclear Plant Renewal Faces Labor Shortage Challenges

Japan is planning to replace its aging nuclear reactors to enhance the nation's energy independence. However, the key issue is that labor shortages are threatening the progress of this effort. According to reports, up to 70% of related companies have reported difficulties in recruiting personnel, placing greater strain on an already tight schedule. The government has approved plans to build up to five new nuclear reactors by 2040, but the human resource bottleneck at the operational level is becoming an increasingly serious problem. The labor shortage not only affects the progress of new projects but also puts pressure on the safe operation and maintenance of existing nuclear power plants. As aging reactors are gradually...

U.S. Team Traces Source of Anomalous Gamma Rays from Zinc-70, Nuclear Magnetic Transitions May Improve Models of Heavy Element Formation

An international research team led by scientists from the Facility for Rare Isotope Beams (FRIB) at Michigan State University has recently identified the source of the large number of low-energy gamma rays emitted by zinc-70 nuclei. The study suggests that magnetic transitions occurring within the nucleus are the key reason for this anomalous signal enhancement. The findings were published in the journal Nature under the title "Magnetic character of the low-energy enhancement in 70Zn." Gamma rays are electromagnetic radiation released when excited atomic nuclei transition to lower, more stable energy levels. For a long time, scientists have observed an anomalous increase in the number of low-energy gamma rays in some atomic nuclei, known as the low-energy enhancement (LEE), but its physical mechanism had remained unclear...

Hungary's Paks Nuclear Power Plant Faces Full Shutdown Due to Record Low Danube Water Level

Affected by persistent drought and high temperatures, the water level of the Danube River at the Budapest section dropped to 23 cm (fixed datum reading, a record low), restricting cooling water intake at the Paks Nuclear Power Plant. Starting Wednesday, July 29, Unit 3 was the first to be shut down; the operator, MVM Paks Nuclear Power Plant Ltd, subsequently stated on its official website that all four units would inevitably be disconnected within the next 24 to 72 hours, with power generation coming to a complete halt. MVM explained that the existing water volume of the Danube is still sufficient to cool the reactors, but the intake pumps can no longer draw water because the riverbed is exposed and the pump inlets are too far from the water surface—an equipment failure rather than an absolute shortfall in cooling water volume. To this end, the Hungarian side deployed 4 pumping barges and 2 floating cranes near the plant as an emergency measure, but with water levels expected to continue falling, a preventive full shutdown remains unavoidable.
