Idaho Lab's DOME Nuclear Test Bed Now Open for Advanced Reactors

Innovations and Collaborations Pave the Way for Advanced Nuclear Technologies

The world of nuclear energy is witnessing groundbreaking advancements as institutions and companies push the boundaries of technology and innovation. From a pioneering nuclear test bed in Idaho to novel agreements in Turkey and Sweden, the industry is setting a new pace for development and deployment of advanced reactors.

Idaho's DOME Facility Leads Nuclear Innovation

Located on the vast Snake River Plain, the Demonstration of Microreactor Experiments (DOME) test bed at Idaho National Laboratory (INL) has opened its doors to private advanced nuclear reactor developers. This unique facility is a milestone in nuclear innovation, offering a platform for testing and demonstrating new reactor designs swiftly.

The DOME test bed, part of the National Reactor Innovation Center, is housed within the Materials & Fuels Complex at INL, and was historically used for developing the EBR-II reactor, a predecessor to modern advanced reactor designs. Its reopening provides a crucial environment for microreactor experiments reaching up to 20 MWt of thermal energy.

INL's Director, John Wagner, emphasized the facility's role in accelerating nuclear innovation by stating, “We are accelerating the next generation of nuclear innovators from concept to demonstration at a pace the industry has not seen in decades.”

This year, DOME will host experiments by Radiant and Westinghouse with their Kaleidos and eVinci reactors, respectively, signifying the test bed's importance in advancing reactor concepts.

DOE Approval Propels Antares Forward

Antares Nuclear has achieved a significant milestone with the U.S. Department of Energy's approval of its Documented Safety Analysis for the Mark-0 reactor, marking the final step before achieving startup and first criticality by July 2026. Antares CEO, Jordan Bramble, praised the achievement, stating, “We are entering the final innings, and that’s incredibly exciting.”

The Mark-0 will serve as a crucial demonstration for validating the technologies and systems planned for Antares's subsequent Mark-1 reactor aimed for release in 2027.

Streamlining Reactor Licensing: NRC's New Approach

The Nuclear Regulatory Commission (NRC) is set to streamline the licensing process for advanced reactors by leveraging existing Department of Energy and Department of War data. This initiative, under Executive Order 14300, aims to expedite nuclear technology deployment while ensuring safety standards.

Jeremy Bowen of the NRC's Office of Advanced Reactors emphasized, “Once DOE or DOW thoroughly tests a reactor design and shows it operates safely, we’re going to build on that work, not repeat it.”

Fluor and X-Energy's Texas Project Takes Shape

Fluor Corporation has partnered with X-energy to advance a groundbreaking nuclear project at Dow’s UCC Seadrift Operations in Texas. This project will replace outdated energy infrastructure with four 80MW small modular reactors, supported by the DOE's Advanced Reactor Demonstration Program.

Microreactors Planned for U.S. Air Force Bases

The U.S. Air Force, in collaboration with the Defense Innovation Unit, anticipates deploying small nuclear reactors at Buckley Space Force Base in Colorado and Malmstrom Air Force Base in Montana by 2030. This move is part of an effort to ensure reliable, secure power for critical military operations.

Nancy Balkus, the Air Force’s deputy assistant secretary, highlighted the strategic significance, stating, “By advancing the use of next-generation nuclear energy, the [Department of the Air Force] is strengthening the energy security of our power projection platforms.”

India Achieves Criticality in Fast Breeder Reactor

India's Prototype Fast Breeder Reactor has reached its first criticality, marking a critical phase in the nation's three-stage nuclear program. The 500 MWe reactor at Kalkpakkam signifies a pivotal step toward India's goal of utilizing its abundant thorium reserves for energy security.

Prime Minister Narendra Modi praised the achievement as a “decisive step towards harnessing our vast thorium reserves in the third stage of the program.”

Turkey Explores Advanced Nuclear with ARC

ARC Clean Technology has signed a term sheet with IC Nuclear & Industry to develop the ARC-100 reactor in Turkey. This collaboration aligns with Turkey's strategic goals to enhance its nuclear capabilities while positioning itself as a regional hub for advanced nuclear solutions.

ARC CEO, James Wolf, expressed enthusiasm, stating, “This collaboration is an important step in ARC’s global market strategy, as we work with leading partners to deploy advanced nuclear solutions internationally.”

GE Vernova Expands SMR Reach in Europe

GE Vernova's partnership with Sweden’s AFRY is set to enhance the deployment of the BWRX-300 small modular reactor across Europe. This collaboration aims to integrate Swedish industrial capabilities into the growing SMR market and support Sweden's nuclear power ambitions.

GVH CEO Jason Cooper emphasized the potential impact, stating, “This agreement reflects our commitment to building a strong Swedish and European industrial ecosystem around the BWRX-300.”
