Three units at France's Gravelines nuclear power plant automatically shut down due to jellyfish intrusion

French utility EDF recently stated on its website that three units at the Gravelines nuclear power plant in northern France automatically shut down after a large influx of jellyfish clogged the filtration system, triggering safety measures. The statement indicated that the incident occurred on August 10, 2026. Due to the jellyfish intrusion, three units at the Gravelines plant automatically shut down, while a fourth unit reduced its power output. The plant has a total of six reactors, of which the fifth reactor had already been shut down for planned maintenance, and the sixth reactor remained in operation. The Gravelines plant experienced a similar situation a year earlier, when a large number of jellyfish entered the relevant water intake and filtration systems, causing four reactors to automatically shut down...

Unanimously Approved! China's First ISO International Standard in the Field of Fusion Fueling Officially Released

On August 10 local time, the international standard ISO 19991:2026, "Fusion Technology — Experimental Magnetic Confinement Fusion Facilities — Ultrasonic Molecular Beam Injection Fueling Technology for Fusion Devices," formulated by China, was officially released. Earlier, during the final voting process, all 12 countries, including France, Germany, and Russia, cast affirmative votes. This is the first ISO international standard in the field of fusion fueling and the second ISO international standard in the fusion field led by the Southwestern Institute of Physics (SWIP) under the China National Nuclear Corporation (CNNC). Ultrasonic molecular beam injection fueling technology is a key fuel supply technology for controlled nuclear fusion devices. This technology, an advanced fusion fueling technology originally developed by China, forms high-speed, directional molecular beams through adiabatic gas expansion. It features high speed, strong directionality, relatively high fueling efficiency, and low particle recycling, significantly enhancing the fuel control capability of fusion devices. It has been applied to more than ten magnetic confinement fusion experimental devices both domestically and internationally.

Scientists from a small town in Uttar Pradesh, India, gain international recognition: exploring AI-assisted nuclear reactor control

Samendra Roy, a scientist and resident of Payagpur in the Bahraich district of Uttar Pradesh, India, along with his team, has recently attracted attention from the international academic community. The research focuses on the potential applications of artificial intelligence in the operation and control of nuclear reactors. The findings have been published in *npj Artificial Intelligence*, a journal under the Nature Publishing Group, marking the team's work's arrival on a prestigious international academic platform. The study primarily explores the role of agent-based physics-informed artificial intelligence in nuclear reactor control. The research team believes that during nuclear reactor operation, control systems often face complex environments and highly challenging decision-making scenarios, and AI technology is expected to play a significant role in the future in areas such as assisting judgment, optimizing control processes, and enhancing operational management capabilities.

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.

US Hanford Submits Permit Modification Applications to Accelerate Tank Waste Cleanup via "Vitrification + Grouting"

The U.S. Department of Energy's Hanford Field Office recently submitted two permit modification applications to the Washington State Department of Ecology, planning to accelerate the cleanup of radioactive waste in tanks at the Hanford site through a dual-track treatment strategy of "vitrification + grouting." The DOE stated that this approach is expected to reduce risks from aging tanks and save taxpayers billions of dollars. The waste primarily targeted by these applications is low-activity liquid waste processed through the Tank-Side Cesium Removal system, which removes more than 99.9% of radioactive materials from the treated waste. The DOE stated that the proposed permit changes would integrate tank-side treatment, grout solidification, and out-of-state disposal into a standardized process to continue advancing the treatment and transfer of some waste beyond the capacity of the Waste Treatment and Immobilization Plant.
