Nuclear NewsNEW Tennessee issues licence for fusion plantThe Tennessee Department of Environment and Conservation granted Type One Energy a byproduct material license for its commercial fusion project at the former Bull Run fossil plant site. This action establishes a state-level regulatory framework for fusion machines, distinct from fission reactor requirements. The developer plans to build a 400 MWe stellarator fusion plant as part of a multi-phase development campus in partnership with local institutions. The Tennessee Department of Environment and Conservation has issued the state's first fusion-specific byproduct material licence to Type One Energy in preparation for its commercial fusion project. Tennessee is the first US state to issue a licence under a new regulatory framework specifically for nuclear fusion machines. ; In 2023, the US...
Nuclear NewsNEW ATLAS, new MARAD partnership, among latest maritime nuclear announcementsThe International Atomic Energy Agency has launched the Atomic Technologies Licensed for Applications at Sea program to support nuclear technology in civilian shipping and floating power plants. Simultaneously, the Maritime Administration signed a cooperation agreement with Core Power, while Newcleo announced a consortium to design a 200-MWe nuclear-powered barge. These initiatives aim to establish regulatory and safety frameworks for deploying advanced reactors in maritime environments by the 2030s. For the nuclear industry, this shift represents a move toward non-traditional markets, requiri...
Nuclear NewsNEW 5 key questions the Army is still working out for its nuclear microreactor planThe U.S. Army has awarded $2.2 billion to five companies to develop and operate 20 nuclear microreactor prototypes at domestic military installations by 2028. The Janus program aims to secure power independence for bases against grid vulnerabilities and fuel supply chain disruptions. Officials acknowledge the technical complexity of the project and the possibility that some participating contractors may fail to meet deployment goals. The Army's top energy official recently walked reporters through a series of questions he’s grappling with as part of the push to deploy nuclear microreactors at...
Nuclear NewsNEW Raven-Flint Selected by DOE to Build America’s Second Uranium Conversion PlantRaven-Flint will construct the Torch pilot conversion facility at Idaho National Laboratory to produce 500 tonnes of uranium hexafluoride annually. The company successfully demonstrated a proprietary conversion process that eliminates the use of elemental fluorine. This project aims to expand domestic conversion capacity, which currently relies on a single facility built in 1958. The NRC has also docketed the company's license application for engineering-scale uranium research. Raven-Flint is selected for the DOE Nuclear Energy Launch Pad at Idaho National Laboratory and confirms production of...
Nuclear NewsNEW Lightbridge Selected for U.S. Department of Energy Launch Pad INL Program to Advance CommercializatiLightbridge Corporation has been selected for the Nuclear Energy Launch Pad initiative at Idaho National Laboratory. This program provides an accelerated pathway for the company to design and build a facility for manufacturing lead test assemblies of its proprietary fuel technology for use in commercial nuclear power reactors. The initiative aims to shorten the timeline for fuel commercialization by utilizing Department of Energy authorization for production-scale testing. By proving manufacturing processes at the Idaho site, the company intends to de-risk the transition to full-scale commerci...

Nuclear NewsNEW Will AI Appetite Unlock or Overload Nuclear’s Supply Chain? Technology companies are increasingly securing nuclear power to meet the continuous energy demands of artificial intelligence data centers. While this influx of private capital offers potential for supply chain expansion, industry experts warn that rapid project scaling could strain existing resources, labor pools, and manufacturing capacity for nuclear components. This surge in demand creates a tension between the need for rapid deployment and the rigorous safety and regulatory standards required for nuclear operations. If managed effectively, long-term tech investments could provide the stab...
Outage NewsNEW Browns Ferry 2 trips offline, unscheduled outage underwayBrowns Ferry 2 began an unscheduled forced short outage on August 27, 2026. This event ended a 448 day streak of operation without an unscheduled outage for the 1,259-MW General Electric BWR/4 unit. The unit has recorded one forced outage so far in 2026, compared to two forced outages during the entirety of 2025.

History & TriviaNEW The 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 physical record of extreme thermal events, potentially offering new insights into material behavior under rapid, high-energy phase transitions. The world changed forever on 6 August 1945. That was the da...
