A batch of radioactive waste from the Korea Atomic Energy Research Institute deemed unsuitable for disposal due to documentation discrepancies

According to disclosures by relevant parties on August 5, a batch of radioactive waste shipped last year by the Korea Atomic Energy Research Institute (KAERI) to the low- and intermediate-level radioactive waste disposal facility (RWDF) in Gyeongju, North Gyeongsang Province, was deemed unsuitable for batch disposal due to inconsistencies between the declared documentation and actual contents. The Korea Radioactive Waste Agency (KORAD) conducted inspections after receiving the waste. KAERI shipped a total of 694 drums of radioactive waste to the disposal facility last year, of which 69 drums were inspected, and 32 were found to be non-compliant. The primary reason for non-compliance was discrepancies between the contents of the documents submitted by the institute and the actual inspection results after receipt. As a result, this batch of waste from the Korea Atomic Energy Research Institute...

Russian Researchers Develop High-Wear-Resistant Steel Sample for Nuclear Waste Processing

Novosibirsk State Technical University (NSTU) recently announced that Russian researchers have developed a steel sample with reinforcing elements. Experimental results show that the durability of this material is approximately 4 times that of 5KhNM tool steel currently used in nuclear power plant waste processing equipment. The research focuses on improving precipitation hardening steel structures. Precipitation hardening steel is a special class of alloy material that, after quenching and holding at specific temperatures, precipitates fine, hard particles within the steel, thereby enhancing strength and wear resistance. The researchers aim to replace existing 5KhNM tool steel with new high-strength alloys...

Researchers at the Institute of Modern Physics, Chinese Academy of Sciences, reveal the dual-directional role of shell effects in multinucleon transfer reactions

Recently, the research team from the State Key Laboratory of Heavy Ion Science and Technology at the Institute of Modern Physics, Chinese Academy of Sciences, together with collaborators, revealed the dual-directional mechanism of shell effects in multinucleon transfer reactions and proposed optimized reaction systems. This study provides new insights for the efficient synthesis of neutron-rich nuclides in the laboratory. The results were published in Physics Letters B. The synthesis and study of neutron-rich nuclides near the neutron magic number 126 are of special scientific significance, as the properties of these nuclides are directly related to how heavy elements such as gold and platinum in the universe are formed. However, efficiently producing these nuclides has long been an experimental challenge. Traditional fusion-evaporation...

Cosmic Rays "Probe" Soil Moisture from Above: Colorado State University Innovates Soil Moisture Monitoring Technology

Researchers at Colorado State University are utilizing a mobile cosmic-ray neutron rover to explore a novel soil moisture monitoring method. This technology is expected to provide data support for hydrological research, particularly in assessing the impacts of wildfires on landscapes. The rover is reportedly capable of estimating soil moisture over large areas by measuring changes resulting from the interaction of cosmic rays from outer space with hydrogen atoms in the soil. Unlike traditional sensors that only capture near-surface data at a limited number of points, or the coarse resolution of satellite remote sensing, this technology offers a mesoscale dataset that falls between the two, enabling more accurate mapping of moisture distribution...

Russia's Vector Research Center Proposes Quantum Dots for Boron Delivery in Neutron Capture Therapy

Russia's Vector Research Center has proposed using quantum dots as targeted boron delivery systems in boron neutron capture therapy (BNCT) to explore more precise approaches to tumor treatment. Yuri Tumanov, the center's chief researcher, presented this research progress at a conference on engineering biology and biopharmaceuticals. Boron neutron capture therapy is a cancer treatment method that combines boron-containing drugs with neutron irradiation. The basic concept involves first allowing boron-containing drugs to accumulate in tumor cells, then subjecting the patient to neutron irradiation, which triggers a nuclear reaction that releases energy concentrated within boron-containing cancer cells, thereby destroying tumor cells. How to construct boron delivery systems that are low-toxicity, highly efficient, and capable of participating in targeted tumor destruction remains one of the key challenges in this field...

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...

Brazilian research team uses stable isotope analysis to trace Amazon timber origins

Brazilian researchers are developing a timber traceability tool based on stable isotope analysis to help identify the origins of illegally logged wood in the Amazon region. Illegal logging is reported to be one of the major causes of deforestation in the Amazon. Local environmental and law enforcement agencies currently typically determine timber origins through plant anatomical characteristics, tree species distribution, and official records such as forest origin documents, but these methods are not always sufficient to prove that timber comes from legal areas. A research team at the Center for Nuclear Energy in Agriculture, University of São Paulo (CENA-USP) is mapping the isotopic distribution of Amazon trees. The method analyzes the ratios of different isotopes of elements such as oxygen, carbon, nitrogen, and strontium in wood cellulose to narrow down the potential harvesting areas of timber. Team leader Luiz Antonio Martinelli stated that stable isotopes are difficult to forge artificially, offering the potential to provide federal police with a more tamper-resistant technical tool.
