The Energy Department announced a significant achievement in nuclear energy development as a microreactor developed by Antares Nuclear Inc. at the Idaho National Lab reached ‘criticality.’ This milestone indicates the reactor has achieved a self-sustaining chain reaction capable of producing a steady release of energy. The development is part of a pilot program initiated by the Trump administration to boost nuclear energy production in the United States.
Trump-Era Initiative
Antares is the first private company to achieve this milestone under the program, which was designed to accelerate nuclear technology advancements by reducing regulatory barriers. Energy Secretary Chris Wright highlighted the achievement as a testament to American innovation and entrepreneurship, emphasizing the potential for nuclear energy to lower costs and enhance national power.
President Donald Trump had signed executive orders in May 2025 to expedite nuclear power development, granting Wright authority to approve certain advanced reactor designs and projects. These orders also limited some regulatory powers of the Nuclear Regulatory Commission, aiming to streamline the process for new technologies.
Future Prospects and Skepticism
While Antares’ system is still years away from commercial use, the company aims to begin electricity production by late 2027, with deployment expected by the end of 2028. The initial focus is on military applications, with CEO Jordan Bramble expressing optimism about the technology’s readiness for deployment.
Despite the progress, some experts remain skeptical about the safety and feasibility of microreactors. Edwin Lyman from the Union of Concerned Scientists criticized the recent developments as publicity stunts, arguing that more testing is needed to ensure safety and commercial viability.
The Trump administration has set a goal to achieve criticality in at least three test reactors by July 4, 2026, coinciding with the nation’s 250th anniversary. In a related effort, the Pentagon and Energy Department demonstrated the potential for rapid deployment of nuclear power by airlifting a small reactor from California to Utah earlier this year.
