US experiment reveals diamond melting behavior under high pressure, potentially advancing inertial confinement fusion research

Researchers at Lawrence Livermore National Laboratory published a new study in Nature Physics documenting the melting process of diamond at pressures approximately three times greater than those at Earth's core. The experiments showed that under high-pressure conditions, diamond floats in liquid metallic carbon, similar to how ice floats in water. This finding helps improve inertial confinement fusion experimental models and provides new evidence for understanding the potential "diamond rain" phenomenon inside ice giant planets such as Neptune and Uranus. The latest melting experiments confirmed that under high pressure, diamond floats in liquid metallic carbon, just as ice floats in a glass of water.

St. Lucie Nuclear Power Plant Unit 1 Manually Shut Down After Three Control Rods Dropped into the Core

According to an event notification submitted to the U.S. Nuclear Regulatory Commission (NRC), Unit 1 of the St. Lucie Nuclear Power Plant, located on Hutchinson Island, Florida, USA, experienced a manual reactor shutdown at 9:47 a.m. Eastern Time on August 13, 2026. At the time of the event, the unit was in Mode 1 and operating at 100% power. The shutdown was caused by three control rods dropping into the reactor core. The U.S. Nuclear Regulatory Commission classified the event as a non-emergency. The licensee stated that the shutdown was completed in accordance with procedures, all systems responded normally after the shutdown, and operators subsequently stabilized the unit in Mode 3, i.e., hot standby condition. Decay heat was removed by diverting steam to the main condenser via turbine bypass valves and the main feedwater system...

U.S. Department of Energy Awards $271 Million to Support Extended Operation of Diablo Canyon Nuclear Power Plant

The U.S. Department of Energy (DOE) recently awarded $271 million to Pacific Gas and Electric Company (PG&E) to support the continued operation of the Diablo Canyon Nuclear Power Plant. The funding will be used to ensure the plant maintains safe and reliable power generation during the license extension period and to support workforce stability. In April of this year, the U.S. Nuclear Regulatory Commission (NRC) approved a 20-year extension of the operating licenses for both units at Diablo Canyon. Under the previous schedule, the plant's two units were originally slated to cease commercial operation in 2025. Assistant Secretary for Nuclear Energy Ted Garrish stated that keeping Diablo Canyon operational is of great significance in meeting California's growing demand for affordable, reliable, and safe electricity. The Civil Nuclear Credit Program is helping protect this critical baseload power source and prevent premature retirement of reliable generation facilities from the grid.

SLAC team observes progressive melting of copper under extreme heat in real time

Researchers at the SLAC National Accelerator Laboratory, under the U.S. Department of Energy, and their collaborators used the Mega-electron-volt Ultrafast Electron Diffraction (MeV-UED) facility to observe in real time the melting process of copper atoms under extreme temperatures. The study was published in Nature Communications. Future fusion power plants will need to replicate fusion reactions that occur inside stars here on Earth. The core plasma can reach temperatures of hundreds of millions of degrees Celsius, while surrounding structural materials must withstand sudden, intense thermal shocks. Copper and its alloys, owing to their excellent thermal conductivity, are considered capable of serving as "heat sinks" in fusion systems...

Study Reveals Three-Dimensional Pore Networks Inside Uranium-Zirconium Metallic Nuclear Fuel

Researchers at the Massachusetts Institute of Technology (MIT), in collaboration with Idaho National Laboratory (INL), conducted three-dimensional imaging studies on irradiated uranium-10 zirconium metallic fuel, revealing the internal pore networks within the fuel and their relationship with chemical changes and fuel-cladding interactions. The researchers believe these results will help improve metallic fuel performance models, providing references for extending the operating cycles of certain reactors and for the design of next-generation sodium-cooled fast reactor fuel systems. Uranium-10 zirconium (U-10Zr) is a uranium-zirconium alloy metallic fuel containing 10% zirconium, which has been extensively tested in sodium-cooled fast reactors such as Experimental Breeder Reactor II (EBR-II) and the Fast Flux Test Facility (FFTF). As advanced reactor research and development progresses, this type of metallic fuel has regained attention, but the details of pore formation, swelling, heat transfer, and interactions with cladding materials under reactor irradiation conditions still require further clarification.
