• NUCLEAR WASTE Technology to Reduce the Impact of Used Nuclear Fuel

    By Marguerite Huber

    Transmutation technologies can significantly reduce the mass, volume, activity and lifespan of commercial used nuclear fuel (UNF) by converting long-living hazardous isotopes into materials that decay more quickly.

  • NUCLEAR POWERVirtual Models Paving the Way for Advanced Nuclear Reactors

    By Marguerite Huber

    Computer models predict how reactors will behave, helping operators make decisions in real time. The digital twin technology using graph-neural networks may boost nuclear reactor efficiency and reliability.

  • NUCLEAR POWER‘The West Will Lead’: Utah, Idaho, Wyoming Team Up on Nuclear Energy Development

    By Katie McKellar

    Utah state leaders are taking the next steps in their efforts to make Utah a major nuclear energy development hub and a “national leader” in developing next-generation energy technology, reaching beyond state lines to do it.

  • ENERGY SECURITYThe Trump Administration Says It Wants a “Nuclear Renaissance.” These Actions Suggest Otherwise.

    By Gautama Mehta and Katie Myers

    For nuclear advocates, it’s an open question whether the Trump administration’s energy officials recognize the scale of the effort that would be required to achieve their purported ambition for a nuclear revival. In fact, some of the actions the administration has taken, such as tariffs and a shake-up at the Tennessee Valley Authority, could be getting in the way of such  revival.

  • NUCLEAR WASTEHow and Where Is Nuclear waste stored in the U.S.?

    By Gerald Frankel

    Around the U.S., about 90,000 tons of nuclear waste is stored at over 100 sites in 39 states, in a range of different structures and containers. For decades, the nation has been trying to send it all to one secure location. Perhaps there will be a temporary site whose location passes muster with the Supreme Court. But in the meantime, the waste will stay where it is.

  • NUCLEAR POWERResearch Drives Innovation in Gen-IV Reactor Safety and Efficiency

    By Kristen Mally Dean

    All U.S. nuclear reactors, which currently provide more than half of the nation’s carbon-free power, are first- or second-generation light water reactors. This means they use water as both a coolant and neutron moderator to control the nuclear reaction and produce useful electricity. Ut researchers pursue all kinds of reactor designs, and nuclear engineers at Argonne frame the future of nuclear design.

  • NUCLEAR WASTEU.S. Supreme Court Takes Up Texas Nuclear Waste Disposal Case

    By Dylan Baddour, Inside Climate News

    The case could establish the nation’s first independent repository for spent nuclear fuel in West Texas, despite the objections of state leaders.

  • NUCLEAR ENERGYExploring the New Nuclear Energy Landscape

    By Josh Blatt

    In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.

  • NUCLEAR POWERA Michigan Nuclear Plant Is Slated to Restart, but Trump Could Complicate Things

    By Izzy Ross

    The owners of a shuttered nuclear plant on the shores of Lake Michigan are still banking on its historic reopening later this year, despite the confusion of President Donald Trump’s first days.

  • NUCLEAR POWERNuclear Has Changed. Will the U.S. Change with It?

    By Christina Pazzanese

    Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.

  • NUCLEAR RESURGENCENuclear Is Here ... and Here and Here

    By Leo Williams

    The Oak Ridge National Laboratory (ORNL) helped start the nuclear age more than 80 years ago, and it remains at the forefront of nuclear research. The lab is also actively involved in promoting east Tennessee’s nuclear industry and consulting with nuclear businesses that move into the area.

  • ENERY SECURITYAssessing Small Modular Reactor Applications to Rebuild a Clean Economy in Post-War Ukraine 

    By Beth Burmahl

    Building on a decades-long partnership, the Argonne National Laboratory will play a leading role in planning and rebuilding the nuclear-generated clean energy infrastructure in post-war Ukraine.

  • NUCLEAR WASTEThe History of WIPP

    By Kim Vallez Quintana

    In 1975, the nation asked Sandia to investigate the possibility of building a repository in New Mexico for the disposal of radioactive transuranic defense waste. Little did those assigned to the project know that the task would absorb most of their careers and become one of the most controversial and important projects in U.S. history.

  • NUCLEAR PLANTSWar Risks from Nuclear Power Plants? Just Look at Zaporizhzhia

    By Henry Campbell

    As evidenced in an International Atomic Energy Agency (IAEA) report released in September, Russia’s occupation of the Zaporizhzhia Nuclear Power Plant in Ukraine continues to create high risk of a nuclear disaster. In considering future conflicts, no one can safely assume that an enemy will avoid targeting nuclear power stations.

  • NUCLEAR PLANTSSafer and More Precise Nuclear Plant Dismantlement

    As the need for technologies to cut and dismantle reactors and internal structures increases due to the end of the operational lifespan of nuclear power plants, an innovative laser cutting technology for nuclear dismantlement has been developed.
