IAEA Publishes Report on Aging Management of Spent Fuel Dry Storage Systems

The International Atomic Energy Agency (IAEA) has published the findings of a decade-long study on aging management of spent fuel dry storage systems. According to IAEA estimates, by the end of 2024, spent fuel discharged from nuclear power plants worldwide had exceeded 400,000 tonnes of heavy metal (tHM). Of this, 106,000 tHM is in dry storage, a long-term storage method that is becoming increasingly common compared with wet storage. Most IAEA member states are still decades away from commissioning permanent spent fuel repositories, which means dry storage systems will likely need to continue operating safely beyond their design lifetimes. Wet storage has been in operation for decades, and the IAEA states that aging management of such facilities is generally well understood. Utilities choose dry storage for its passive safety features, and many dry storage facilities have already received license extensions. The IAEA expects demand for dry storage to continue growing, with service periods extending well beyond the original 20-to-40-year licensing terms, potentially exceeding 120 years. Aging management programs (AMPs) are therefore needed to verify continued safe operation.

MIT Develops Ultrafast X-ray Thermometry Method to Observe Heat Transfer in Multilayer Chip Structures

Researchers at the Massachusetts Institute of Technology (MIT) have developed a new method for observing how heat transfers through multilayer materials, which can be used to precisely measure heat flow variations inside electronic devices such as computer chips. The findings have been published in Nature Communications. As computer chips continue to shrink in size and power density keeps rising, device overheating has become a major factor limiting performance improvements. Traditional heat flow measurement methods face limitations when dealing with the multilayer structures of real electronic devices—for example, the commonly used time-domain thermoreflectance method struggles to distinguish heat transport in different material layers, while infrared imaging and other approaches also fail to capture rapid changes at microscopic scales. To address this issue...

Visualization of the Materials Discovery Cloud, a physics-based AI framework that integrates experimental data, simulations, and high-performance computing to predict how tiny defects affect the performance and lifespan of microelectronic devices. (Image provided by ChatGPT.) Microelectronic devices are widely used in smartphones, laptops, secure communications, and artificial intelligence hardware. As device dimensions continue to shrink and operating speeds increase, tiny defects within materials and at interfaces have a more pronounced impact on device stability. These defects can cause overheating, leakage current, switching instability, and other issues, or in certain conditions, improve electrical or thermal performance. Identifying critical defects and understanding their evolution under real-world operating conditions has become a key challenge in the design of next-generation microelectronic materials.

Final Voyage Completed for Rebar Cage Sea Transport to Hinkley Point C Nuclear Power Station

This summer, the cargo vessel Anfield Peak departed from the Port of Bristol in the UK, heading to Hinkley Point C Nuclear Power Station in Somerset. This marked the vessel's final voyage for the related transport mission. Previously, it had made over 100 round trips between the two locations, delivering factory-prefabricated rebar cages to the nuclear construction site. These rebar cages are large in volume and high in density, serving as critical foundational components in civil engineering construction. Under traditional practices, such rebar cages are typically prefabricated on-site before concrete pouring. The Hinkley Point C project, however, has shifted part of the rebar cage prefabrication process to a factory in Bristol, with the cages then transported by sea to the site for installation...

Department of Plasma Physics and Fusion Engineering at the University of Science and Technology of China Proposes New Three-Dimensional Magnetic Field Configuration for Stellarators

Stellarators confine high-temperature plasma using three-dimensional magnetic fields generated by external coils, enabling steady-state operation without relying on plasma current and avoiding instabilities such as disruptions, making them the fastest-growing technological route globally. However, if the three-dimensional magnetic field is not carefully optimized, trapped particles can experience significant radial drift, leading to a substantial increase in neoclassical transport losses. To suppress this drift, the magnetic field must satisfy the "omnigenity" condition, meaning that the time-averaged radial drift of all trapped particle orbits is zero. The most widely applied class of omnigenous magnetic fields is poloidal omnigenity (PO), and such configurations are also commonly referred to as quasi-isodynamic (QI) configurations...
