Europe's High Temperatures and Droughts Impact Nuclear Power Operations, Ukrainian Expert Says Climate Adaptation Tied to Energy Independence

Recent prolonged high temperatures, droughts, and falling river levels across Europe have put pressure on the operation of some nuclear power plants that rely on river water for cooling. Nuclear facilities in France, Hungary, Romania, and Slovenia have successively experienced power reductions or shutdowns, forcing some countries to ease supply pressure through electricity imports and adjusted consumption arrangements. Katie Huff, a professor of nuclear engineering at the University of Wisconsin-Madison, stated that the impact of climate change on nuclear power operations is mainly reflected in two aspects: first, droughts lower river levels, making it difficult for plants to obtain sufficient cooling water; second, when air and water temperatures are high, nuclear plants face stricter restrictions on discharging warm water into rivers to avoid further affecting the aquatic environment.

Ikata Nuclear Power Station Reports 5 Notifiable Events in July, None Causing Radiological Environmental Impact

Shikoku Electric Power Co. reported on August 10 that the five events reported to Ehime Prefecture, Ikata Town, and relevant local governments from the Ikata Nuclear Power Station in July 2026 did not fall under legally required reporting events and caused no radiological impact on the environment. The five events were as follows: On July 3, an employee of a partner company at the Ikata Nuclear Power Station experienced physical discomfort at an office location in a non-controlled area and was transported by ambulance at 17:18 that day. The employee was conscious at the time and experienced no radiation exposure or radioactive contamination. On July 16, during the decommissioning process of Unit 2 at the Ikata Nuclear Power Station, seawater leakage was discovered at the flange of the seawater outlet pipe of emergency diesel generator 2B in the reactor auxiliary building. After maintenance personnel determined that a detailed inspection of the flange was required, the leak point was isolated, and the leakage was confirmed to have stopped at 15:38 that day. The maximum estimated volume of leaked seawater was approximately 7 cubic meters, all of which was recovered in the floor drain sump within the building and did not flow outside. Subsequent inspection revealed a through-hole approximately 7 mm in diameter at the flange, and the station replaced the flange and confirmed water flow integrity, restoring normal conditions at 14:05 on July 17. This event did not affect the unit or cause radiological environmental impact, and further investigation into the cause will be conducted.

U.S. Laboratories Plan "Materials Discovery Cloud" to Use AI to Predict Impact of Defects in Microelectronic Devices

Researchers at the U.S. Department of Energy's Argonne National Laboratory, Lawrence Berkeley National Laboratory, Oak Ridge National Laboratory, and Northwestern University are planning to develop a Materials Discovery Cloud platform that leverages a physics-based artificial intelligence framework to predict how tiny defects affect the performance and lifespan of microelectronic devices. 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.
