U.S. Completes Mechanical Property Measurements of Irradiated HALEU TRISO Fuel Particles

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

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.

Sweden's First New Nuclear Reactor Could Be Operational by Mid-2030s

Sweden's First New Nuclear Reactor Could Be Operational by Mid-2030s

Sweden's Minister for Energy and Industry, Ebba Busch, who also leads the Christian Democrats (KD), stated at a public hearing on September 3 that the country's first newly built nuclear reactor could be operational by the mid-2030s. When asked when the new nuclear unit could be connected to the grid, Busch indicated the mid-2030s. She also noted that the new nuclear project would not rely on direct state funding. However, the Swedish government has previously prepared a support framework for new nuclear construction. The arrangements could involve financial support amounting to hundreds of billions of Swedish kronor, including loans and electricity price guarantees totaling approximately 400 billion Swedish kronor. Busch stated that this is indeed a substantial sum, but its nature is that of loans and price hedging arrangements targeting critical infrastructure.
