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.

Wachtebeke Municipal Council Reintroduces Nuclear Power Plant Motion

The municipal council of Wachtebeke, Belgium, has once again seen a motion regarding the construction of a nuclear power plant in Paulina Polder, but this time, unlike before, the motion has gained the support of the far-right PVV party. Previously, the plan had been highly controversial, with local residents and environmental organizations strongly opposing the construction of a new nuclear power plant in this sensitive wetland area. They fear irreversible environmental impacts and question the necessity of building new nuclear plants during the energy transition. The introduction of this motion marks a further strengthening of opposition to the project. The PVV's support increases the likelihood of the motion passing and places greater pressure on local authorities. More...

Buried Cesium-137 Sealed Source Discovered by Texas Patrol Officer Near Roadside in Midland County

According to the Texas Department of Public Safety, a corporal with the department recently discovered a buried cesium-137 sealed radioactive source with an activity of 100 millicuries during a routine patrol near a roadway in Midland County. The incident resulted in no injuries or radiation contamination, and public safety was not threatened. On July 24 local time, the corporal, assigned to the department's Radioactive/Nuclear Threat Detection Section, was patrolling near South County Road 1210 when the vehicle-mounted radiation detection system activated. He then used other detection equipment to survey the surrounding area and traced the radiation signal to an underground location. To ensure safe disposal, he requested assistance from local, state, and federal...

Units 3 and 4 of Dukovany Nuclear Power Plant to Undergo Joint Maintenance of Shared Systems

Dukovany Nuclear Power Plant staff will initiate a planned extended outage for Unit 4 on the evening of August 1, while Unit 3 will remain in its outage state. Both units will be offline simultaneously in August, and the plant will use this window to conduct comprehensive inspections, maintenance, and modernization of the shared facilities of Units 3 and 4. Bohdan Zronek, member of the Board of Directors of ČEZ Group and head of the nuclear energy division, stated that the simultaneous shutdown of Units 3 and 4 at Dukovany will place the plant under an intensive work schedule over the coming weeks. Experts from ČEZ and its suppliers will handle hundreds of tasks, and the effectiveness of the outage work depends on precise coordination across all stages. According to...

IIT Develops Novel Nanomaterial for Efficient Recovery of Rare Earth and Uranium Resources

Researchers at the Indian Institute of Technology Roorkee have developed an acid-resistant magnetic nanocomposite capable of recovering uranium and rare earth elements from acidic leach solutions. The material consists of core active nanoparticles encapsulated in a protective silica layer, enabling efficient absorption and extraction of these valuable resources in complex acidic aqueous media. By synthesizing the silica shell using biocompatible reagents, the researchers not only enhanced the material's corrosion resistance but also made it safer and more environmentally friendly. This novel nanocomposite demonstrated exceptional performance in laboratory tests, recovering up to 370 grams of uranium and rare earth elements per kilogram of material. It can operate effectively not only under conditions such as natural groundwater...

U.S. Explores New Methods for Lunar Ice Detection Using Synchrotron X-ray Microtomography and Seismic Models

On July 31, researchers at Lawrence Berkeley National Laboratory, in collaboration with scientists from the University of Maryland and the University of Hawaii, proposed a new method for locating subsurface ice deposits on the Moon using seismic waves. The findings, published in the journal Science Advances, are expected to provide a reference for interpreting detection data and locating water resources in future lunar landing missions. The research focuses on how subsurface lunar materials respond to seismic waves. The team developed computational models to predict the behavior of lunar subsurface media of varying compositions under seismic wave excitation. Experimental results showed differences in seismic response between ice-bearing and dry rocks, indicating that seismological methods have the potential to identify ice layers buried beneath lunar regolith and rock.

Four new units at India's Kudankulam nuclear power plant delayed by three years, cost overrun of 55% to $14.4 billion

The construction cost of four new units at the Kudankulam nuclear power plant being built by Russia's Rosatom in India has increased by 55% since 2024 due to delays. Each unit has a capacity of 1 gigawatt, and the updated total construction cost has reached 1.38 trillion Indian rupees (approximately $14.4 billion). Among them, the construction cost of Units 3 and 4 has increased by 73%, while the cost of Units 5 and 6 has risen by 40%. Russia had previously provided India with $4.2 billion in state credit for the construction of Units 3 and 4. Indian officials stated that the reasons for the delays include the impact of the COVID-19 pandemic, difficulties in the supply of specific materials and equipment, and problems faced by contractors.

Czech research team develops minimally invasive radiocarbon dating sampling method to aid dating of prehistoric rock art

A research team at the Czech Radiocarbon Laboratory (CRL) of the Nuclear Physics Institute of the Czech Academy of Sciences has developed a minimally invasive sampling method for dating carbon-based rock art, enabling the acquisition of materials needed for radiocarbon dating with virtually no damage to the rock art's appearance. After sampling, the outline of the rock art remains intact, with only a slight lightening of color in the sampled area. This method provides a new technical pathway for dating cave paintings of historical value. In the past, sampling of cave paintings was often strictly restricted for heritage conservation reasons, which also hindered related chronological determination efforts. The new method, through a gentler sampling approach, enhances the feasibility of dating carbon-based rock art while maximizing the preservation of its scientific and cultural value...
