South Korean civic groups oppose construction of spent fuel storage facility at Hanbit Nuclear Power Plant site
On September 4, the Joint Action Organization Against Hanbit Nuclear Power Plant in the Honam region of South Korea held a press conference in front of the high-level radioactive waste forum venue in Gochang County, North Jeolla Province, demanding the cancellation of plans to build a storage facility at the Hanbit Nuclear Power Plant site and proposing fundamental measures to address nuclear waste issues. The organization stated that Korea Hydro & Nuclear Power (KHNP) is pushing forward with the construction of temporary storage facilities at the plant site on the grounds that the spent fuel pools at Hanbit Nuclear Power Plant may reach saturation by 2030. The organization argued that this move fails to adequately respond to the opinions of residents near the plant and amounts to unilaterally shifting the burden of nuclear waste onto the local community. The organization stated that the current plan involves building storage facilities at the existing nuclear power plant site...

Russian Research Team Synthesizes Novel Metal-Organic Framework Material Capable of Immobilizing Radioactive Cesium
The Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences has synthesized a novel metal-organic framework material containing neptunium and cesium atoms. Research shows that this material is insoluble in water, resistant to high temperatures and intense radiation, and can stably "lock" radioactive cesium within its own structure, offering new insights for research on radionuclide immobilization and radioactive waste treatment materials. Metal-organic framework materials are a class of materials with high porosity and controllable crystal structures, whose lattices are typically composed of metal atoms connected by organic molecules. Since their pore sizes and structures can be tuned at the molecular level, these materials can be used to adsorb gases or specific nuclides. However, compared with traditional adsorbents such as activated carbon...

U.S. Completes Mechanical Property Measurements of Irradiated HALEU TRISO Fuel Particles
Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) have completed mechanical property measurements of irradiated high-assay low-enriched uranium (HALEU) TRISO fuel particles, providing new experimental data for the development and qualification of next-generation nuclear fuels. This is an optical cross-sectional image of an irradiated AGR-2 TRISO fuel particle in the Irradiated Fuels Examination Laboratory at Oak Ridge National Laboratory. Image credit: Oak Ridge National Laboratory, U.S. Department of Energy. TRISO fuel, or tri-structural isotropic fuel, features particles coated with multiple protective layers, typically including pyrolytic carbon layers and a silicon carbide layer. This structure provides strong fission product retention capability and is considered one of the key fuel options for advanced reactors, particularly high-temperature gas-cooled reactors. Understanding the property changes of these coatings after irradiation is a critical step in predicting fuel performance under reactor operating conditions.

Fudan team extracts CKM matrix element |Vus| via quantum entanglement in collider experiment for the first time
On the evening of September 2, 2026, Beijing time, the team led by Luo Tao from the Institute of Modern Physics at Fudan University, together with collaborators, published a research achievement titled "Exploring baryon semileptonic decays through polarization and entanglement" in Nature. This study, for the first time in a collider experiment, utilized quantum entanglement and polarization information to extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |Vus|, providing a new experimental pathway for precisely testing the Standard Model of particle physics. The CKM matrix describes the strength of transitions between different quarks under the weak interaction. Among them, |Vus| corresponds to the transition from the strange quark to the up quark, and its numerical precision is related to the test of the three-generation quark mixing mechanism in the Standard Model. Currently, results for |Vus| obtained from different decay processes still show discrepancies, and the unitarity test of the first row of the CKM matrix also exhibits some tension, necessitating more independent measurement methods for verification.

Non-compliant Welding Procedures at Two Units of South Korea's Hanbit Nuclear Power Plant
The Hanbit Nuclear Power Plant headquarters of Korea Hydro & Nuclear Power Co., Ltd. (KHNP) recently confirmed that Units 1 and 2 of the plant had used welding procedure specifications (WPS) that had not undergone impact testing during maintenance of the component cooling water heat exchangers. A retrospective inspection found that among 14 repair activities conducted since the relevant heat exchangers were replaced in 2007, 6 cases involved similar non-compliance. The issue was identified during the 28th planned preventive maintenance outage of Hanbit Unit 1. Inspections revealed that some welding procedure specifications used for repairs to the water chambers of the component cooling water heat exchangers did not meet requirements, involving repair work on worn areas inside the heat exchanger water chambers in the cooling systems of Units 1 and 2.
