Hungary Plans to Sink Two Barges Near Paks Nuclear Power Plant to Raise Danube Water Level

Hungarian authorities plan to conduct controlled sinking of two giant barges, each about 80 meters long, in the river section near the Paks Nuclear Power Plant on August 14, aiming to raise the local water level of the Danube and ensure cooling water supply for the nuclear power units. According to European sources, after the two barges are sunk, the water level in the relevant river section is expected to rise by about 20 centimeters. Recently, persistent high temperatures across many parts of Europe have driven the Danube's water level to a low point, putting pressure on water intake and power generation along the river. The Paks Nuclear Power Plant is the only operating nuclear power plant in Hungary. Due to the low water level of the Danube, the plant's power output has dropped to about 25% of its installed capacity. Earlier this week, Hungarian authorities also announced plans to build a riverbed weir on the Danube. Under current expectations, the project could raise the water level in the relevant river section by about 1 meter.

Linn County, Iowa, rejects rezoning application for data center site near nuclear power plant

The Linn County Board of Supervisors in Iowa said Monday it will not proceed with amendments to the EU-2 zoning district. This decision means that large data centers will not be permitted to be built near nuclear facilities through this zoning rule for the time being. The current EU-2 zoning primarily allows for nuclear power generation facilities, nuclear waste storage facilities, and natural gas power generation facilities, and does not list large data centers as permitted uses. The zoning adjustment drew attention due to the potential restart of the Duane Arnold Energy Center near Palo. If the nuclear facility were to resume operations, it could provide a stable power source for energy-intensive data centers, prompting interest from data center companies in surrounding...

Fractionated radiotherapy did not significantly alter surface properties of two types of dental restorative composites

On August 5, a recently published in vitro study showed that under a simulated clinical head and neck cancer radiotherapy regimen, the surface microhardness and roughness of two modern dental restorative composites did not change significantly. The study focused on the effects of therapeutic ionizing radiation on the durability of dental restorative materials. After head and neck cancer patients receive radiotherapy, the oral environment may change, including reduced saliva secretion, mucositis, radiation caries, and other issues, which may affect the surface condition and long-term performance of restorations. To this end, the research team selected Giomer resin composite based on glass ionomer technology and Or...

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...

Canadian laboratory validates molten salt separation process with real spent fuel, extracting nearly 90% of plutonium in 24 hours

A chemical experiment in Canada involving real commercial reactor spent fuel has achieved noteworthy progress. Canadian Nuclear Laboratories, in shielded hot cells at Chalk River, used irradiated spent fuel from CANDU reactors to validate the first phase of Moltex Energy's waste-to-stable-salt process. The experiment showed that within 24 hours, 89.4% of the plutonium was transferred into the molten salt; by 60 hours, this proportion rose to 94.3%. Meanwhile, the vast majority of uranium remained outside the salt phase, indicating that the process exhibits strong selectivity in separating target elements. This process, named WATSS, is not a plutonium purification route but rather a group separation technology. In addition to large quantities of uranium, spent fuel contains fission products as well as transuranic elements such as plutonium and americium, the latter being a significant source of long-term radiological risk. WATSS uses high-temperature chloride molten salt and specific reducing metals to convert transuranic oxides into salt-soluble forms, while most uranium oxides remain solid. In this experiment, researchers used niobium as the reducing metal; after 24 hours, only 0.05% of uranium entered the salt, dropping to 0.02% after 60 hours, demonstrating that it does not carry large amounts of uranium into the molten salt system.

DXA Screening Among U.S. Medicare Population Declines 35% Over Nearly Two Decades

A new study shows that between 2005 and 2023, the rate of dual-energy X-ray absorptiometry (DXA) examinations among U.S. Medicare beneficiaries declined significantly, by 35%. DXA is commonly used for bone density testing and osteoporosis-related screening, and the findings suggest that disparities in screening access across different populations are widening. Researchers analyzed claims data from more than 5 million Medicare beneficiaries. The results showed that DXA utilization fell from 7,255 exams per 100,000 beneficiaries in 2005 to 4,690 per 100,000 beneficiaries in 2023. The study was published in Osteoporosis International. The decline was not uniform across populations...

Basic research cracks an application challenge that has persisted for nearly half a century: quantitative prediction of neutron irradiation swelling via ion irradiation

Whether advanced nuclear energy systems can operate safely over the long term depends on the ability of structural materials to resist neutron irradiation damage. Neutrons create numerous atomic-scale defects in materials, which gradually aggregate into nanoscale cavities, ultimately causing material swelling, dimensional instability, and performance degradation. However, obtaining high-dose neutron irradiation data often requires years or even more than a decade, with high costs and post-irradiation sample radioactivity; in contrast, ion irradiation can simulate years of accumulated damage within days and is therefore widely adopted (approximately 95% of irradiation experimental data in existing literature come from ion irradiation). But the dose rate of ion irradiation is typically 3—4 orders of magnitude higher than that of neutron irradiation, making direct conversion between the two results difficult. Recently, the research team of Wang Chenxu and Wang Yugang from the Institute of Heavy Ion Physics, School of Physics, and the State Key Laboratory of Nuclear Physics and Nuclear Technology at Peking University, in collaboration with researchers from the University of Tennessee and other institutions, established a quantitative relationship between material swelling and irradiation dose and dose rate at fixed temperatures based on cluster dynamics simulations, theoretical derivations, and ion irradiation experiments, achieving prediction of neutron irradiation swelling using rapid ion irradiation and providing a new tool for rapid screening and lifetime evaluation of nuclear materials.
