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...

Utah Energy Hub Seeks Diversified Growth: Coal, Nuclear, and Data Centers in Parallel Development

On August 12, at the Carbon & Emery Energy Collaborative meeting held in Price, Utah, local government and energy companies discussed regional economic development, coal production, nuclear energy projects, and the electricity demand driven by data centers. The core message conveyed at the meeting was that while coal remains a vital pillar for Carbon County and Emery County, the future of energy and economic growth no longer depends on a single source, but rather requires the combined support of coal, nuclear energy, and emerging industries. Carbon County Commissioner Jared Haddock noted that the county's taxable value has decreased by approximately $1 billion over the past decade, putting greater pressure on local government to maintain its tax base. To avoid...

U.S. nuclear company TerraPower partners with Korean firms to advance Natrium advanced nuclear deployment in America

U.S. nuclear company TerraPower, backed by Bill Gates, is accelerating the commercialization of its advanced nuclear reactors. The company announced on August 14 that it has reached cooperation agreements with South Korea's Hyundai Engineering & Construction and SK Innovation, aiming to advance the deployment of up to eight 345 MW Natrium reactors in the U.S. nuclear expansion. The first plant is expected to be completed by 2030, a timeline that underscores the urgency of deploying next-generation nuclear technology in the United States. Under the agreement, Hyundai Engineering & Construction has been selected as the engineering, procurement, and construction contractor for up to eight future Natrium reactor projects. The cooperation arrangement also includes related financing guarantee mechanisms, intended to enhance project bankability and reduce uncertainties in the early stages of large-scale construction. TerraPower President and CEO Chris Levesque stated that this marks a new phase of international cooperation with leading Korean institutions, reflecting the growing reliance of advanced nuclear projects on cross-border supply chains and engineering capabilities.

Idaho National Laboratory's Hot Fuel Examination Facility Named U.S. Nuclear Historic Landmark

The American Nuclear Society (ANS) recently designated the Hot Fuel Examination Facility (HFEF) at Idaho National Laboratory (INL) as a Nuclear Historic Landmark. Since becoming operational in 1975, the facility has conducted post-irradiation examination of nuclear fuel and materials, and continues to support research on advanced reactors, commercial nuclear fuel, and related energy security. HFEF is located within the Materials and Fuels Complex (MFC) at Idaho National Laboratory and houses the largest inert-atmosphere hot cell in the United States dedicated to nuclear materials research. The hot cell operates in an argon environment and features approximately 4-foot-thick shielding walls, enabling remote, non-destructive, and high-precision examination of highly irradiated fuel and material samples while reducing worker radiation exposure.
