Nuclear NewsNEW See inside Iowa's only nuclear power plant, set for restart in 2029NextEra Energy secured a 1.9 billion dollar federal loan to restart the shuttered Duane Arnold nuclear plant in Iowa. The 562-megawatt facility aims to resume commercial operations by the first quarter of 2029. Most of the generated electricity will supply Google data centers. The multi-billion dollar recommissioning project faces regulatory hurdles and a legal challenge from an advocacy group regarding radioactive waste storage. Industry observers note that the restart highlights a broader federal push to bring closed reactors back online to satisfy growing energy demands from the technology sector. NextEra wins $1.9 billion government loan to restart Duane Arnold nuclear plant. Costs will reach 'multiple billions of dollars,' exec says. PALO — Ray Wheaton warned visitors to hang onto the...

Nuclear NewsNEW New Mexico land commissioner announces uranium mining ban on state trust landsNew Mexico Land Commissioner Stephanie Garcia Richard signed an executive order banning new uranium mining projects across more than 13 million acres of state trust lands. The directive aims to prevent potential environmental and public health contamination from future extraction while prioritizing the cleanup of approximately 50 abandoned legacy sites located on state properties. Future land commissioners retain the authority to overturn the order. Garcia Richard said Friday that the risks of environmental and health harms from uranium mining outweigh any revenue to state coffers. New Mexico...Core Content
Core ContentNuclear NewsNEW Lightbridge Secures Access to Idaho National Laboratory's Advanced Test Reactor Loop Facility to IrrLightbridge Corporation has secured access to the Advanced Test Reactor loop facility at Idaho National Laboratory to conduct irradiation testing on its proprietary fuel rodlets. This five-year project involves testing uranium-zirconium alloy fuel in both cylindrical and multi-lobe geometries under controlled conditions that replicate the environment of a commercial light-water reactor. This testing phase is a requirement for fuel qualification and provides the empirical data necessary for regulatory review and utility adoption. By subjecting fuel samples to prototypic coolant chemistry, tempe...Core Content

Nuclear NewsNEW More than a Decade of Data to Ensure a Lifetime of Reactor SafetyArgonne National Laboratory concluded a 14-year testing program at the Natural Convection Shutdown Heat Removal Test Facility to validate passive safety systems for advanced reactors. The generated datasets allow developers to verify modeling codes for decay heat removal without human intervention or external power. These results support the design and licensing of Generation IV reactors by providing empirical data on air and water-based cooling systems. Researchers at Argonne National Laboratory in Illinois completed a 14-year campaign to help inform the safety features of new advanced reacto...Core Content
Core ContentNuclear NewsNEW FIA white paper guides Agreement States on fusion regulationThe Fusion Industry Association released a white paper offering guidance to Agreement States regarding the regulation of commercial fusion facilities. The document outlines strategies for states to prepare their licensing programs, manage radioactive materials, and address potential regulatory gaps. It encourages early collaboration between states to establish consistent oversight and reciprocity frameworks. The NRC plans to regulate fusion under a framework similar to particle accelerators, shifting primary oversight responsibilities to Agreement States. Because these states will manage licensing, inspection, and decommissioning, the industry faces a decentralized regulatory landscape. Establishing clear, predictable state-level policies is necessary to attract capital investment and ensure developers can navigate the deployment of commercial-scale fusion projects across multiple jurisdictions. The Fusion Industry Association has released a white paper providing guidance to current and future Agreement States on how to prepare for potential commercial fusion energy companies that ma...Core Content

Nuclear NewsNEW Google’s revived nuclear power plant gets $1.9B loan from US governmentThe U.S. Department of Energy has issued a $1.9 billion loan to NextEra Energy to support the restart of the Duane Arnold Energy Center in Iowa. The facility, which has been shuttered since 2020 following storm damage, is scheduled to return to service by 2029 with a capacity of 615 megawatts. This project reflects a broader trend of tech companies securing firm, carbon-free power from retired nuclear assets to support the energy demands of AI data centers. As utilities face rising electricity consumption, the refurbishment of mothballed reactors provides a faster path to grid capacity than ne...Core Content

Nuclear NewsNEW West Virginia Takes ‘Significant Step Forward’ In Campaign To Host Federal Nuclear CampusWest Virginia has signed a memorandum of understanding with the U.S. Department of Energy to compete as a potential site for a nuclear lifecycle innovation campus. The state joins Idaho, Tennessee, Utah, Oklahoma, and Louisiana in the selection process for the facility, which aims to centralize nuclear fuel and technology development. The proposed campus would integrate fuel fabrication, enrichment, reprocessing, and waste storage, potentially supporting small modular reactors for manufacturing and power generation. This initiative aligns with federal goals to quadruple domestic nuclear capaci...Core Content

History & TriviaThe Hiroshima Atomic Blast Forged a Metal Never Seen Before on EarthGeologists led by the University of Florence have identified a previously unknown iron-chromium alloy within microscopic fallout debris from the 1945 Hiroshima atomic bombing. The 10-micrometer grain exhibits a complex, highly ordered cubic crystal structure that formed due to the extreme temperatures and rapid cooling rates of the nuclear fireball. This discovery highlights that nuclear blast debris contains a unique library of metastable materials that are difficult to replicate in laboratory settings. For the nuclear industry, these findings demonstrate that fallout particles serve as a phy...Core Content
