  • Project Pele, DOD’s HTGR Mobile Nuclear Microreactor, Breaks Ground

    Groundbreaking has kicked off at Idaho National Laboratory (INL), where Project Pele—the Department of Defense’s (DOD’s) full-scale transportable microreactor prototype—will be placed for testing in 2026. When operational, the reactor will become the “first-ever Generation IV nuclear reactor to generate electricity in the U.S.,” the DOD said on Sept. 24. Project Pele, developed under a […]

  • DOD Advances X-Energy Mobile Nuclear Microreactor as Second Project Pele Design

    The Department of Defense (DOD) has moved to develop a second transportable microreactor under Project Pele, granting X-energy a contract option to advance the design of its mobile advanced nuclear microreactor prototype. The one-year contract option will continue to provide funding for X-energy’s nuclear technology development, allowing the firm to develop its design to meet […]

  • X-energy and Dow Will Deploy a 320-MWe Xe-100 Nuclear Facility at Gulf Coast Site

    X-energy will demonstrate its four-unit 320-MWe Xe-100 advanced nuclear reactor facility under the Department of Energy’s (DOE’s) Advanced Reactor Demonstration Program (ARDP) at a Dow site in the U.S. Gulf Coast region by the end of the decade—not in Washington State as originally planned. The shakeup stems from a joint development agreement (JDA) the nuclear […]

  • DOD Picks BWXT Design for ‘Project Pele’ Prototype Nuclear Microreactor 

    The Department of Defense (DOD) has picked BWX Technologies’ (BWXT’s) microreactor design for its “Project Pele” full-scale transportable prototype. The selection closes out a much-watched contest with X-energy for the contract from the DOD’s Strategic Capabilities Office (SCO) to build and operate what could be the nation’s first advanced microreactor.  Lynchburg, Virginia-based BWXT will now […]

  • Green Light for Project Pele, Defense Department’s Mobile Nuclear Microreactor Demonstration

    The Department of Defense (DOD) will push forward on Project Pele, a much-watched mobile microreactor prototype, and demonstrate its full operation for a minimum of three years at an Idaho National Laboratory (INL) site. The DOD’s Strategic Capabilities Office (SCO) on April 15 formally released a record of decision (ROD) to proceed with the program, […]

  • China Starts Up First Fourth-Generation Nuclear Reactor

    The first of two units at China’s much-watched high-temperature gas-cooled modular pebble bed (HTR-PM) demonstration project was successfully connected to the grid on Dec. 20. The achievement marks a major

  • DOE Has Chosen Advanced Nuclear Reactor Demonstration Winners

    The Department of Energy (DOE) on Oct. 7 notified Congress that it has chosen recipients for its Advanced Reactor Demonstration Program (ARDP) and will make its selections public “next week.” The ARDP program, which the DOE officially launched on May 14, will essentially focus DOE and non-federal resources (through cost-shared agreements with industry) to enable […]

  • THE BIG PICTURE: Small Modular Reactors

    Interest in small modular reactors (SMRs) has ramped up of late owing to applications in niche electricity or energy markets where large reactors would not be viable—such as for cogeneration in countries with small grids, remote and off-grid areas, and for nuclear/renewable hybrid projects. Modular attributes may also enable SMRs to target the economics of […]

  • China Advances HTGR Technology

    China’s State Nuclear Power Technology Corp. (SNPTC) has completed the installation of its high-temperature gas-cooled reactor (HTGR) project, the joint venture told the International Atomic Energy Agency

  • Indonesia Considers Thorium Molten Salt Reactors

    Power-short Indonesia has been mulling building a nuclear power plant for nearly 15 years, and it is exploring a number of novel options, including high-temperature gas-cooled reactors (HTGRs) and a thorium

  • X-energy and Southern Nuclear Collaborate on Advanced Reactor Development

    GREENBELT, Md., Aug. 22, 2016 /PRNewswire/ — X Energy, LLC (X-energy) and a subsidiary of Southern Nuclear Operating Company (Southern Nuclear) have entered into a memorandum of understanding as a step toward commercializing and deploying X-energy’s High Temperature Gas-cooled Reactor (HTGR): the Xe-100. The Xe-100 reactor series will produce zero-emission energy around the clock to […]

  • On the Nuclear Frontier: New Designs Aim to Replace LWRs

    Generation III nuclear reactors have not shown much ability to overcome the weaknesses of conventional Gen-II light-water reactor technology, offering at best evolutionary approaches. Is there room for a more revolutionary approach? Many parties are exploring new technologies, but it’s impossible to tell which, if any, will succeed. Last August, Andy Revkin, The New York […]
