Idaho National Laboratory (INL) and private nuclear companies have achieved a significant breakthrough as two nuclear reactors attained criticality shortly before July, marking a fresh chapter in U.S. nuclear energy development. The milestone was commemorated at the Mountain America Center in Idaho Falls, where hundreds of INL staff, state officials, and representatives from nuclear firms gathered to highlight this progress.
U.S. Energy Secretary Chris Wright credited the momentum to policy support from the Trump Administration, emphasizing a recommitment to America's nuclear capabilities after years of stagnation. Wright noted that the administration set an ambitious target through Executive Order 14301: for three reactors to go critical by July 2026. This goal aimed to revitalize nuclear innovation and energy production within just over a year of the directive's release.
The Reactor Pilot Program, involving ten private nuclear firms, has seen early achievements with Antares Nuclear Inc. reaching criticality at INL in early June, followed by Valar Atomics Inc. in Utah mid-month. Under the authorization of the Department of Energy’s Under Secretary Kyle Haustveit, Aalo Atomics Inc. is poised to reach criticality in the coming days, illustrating the expanding scope of commercial nuclear ventures.
Wright described President Trump’s leadership style as instrumental in reigniting the nuclear sector, highlighting his unwavering belief in American ingenuity and the strategic importance of energy independence. Despite Trump's background outside of energy, Wright said the president understood the sector’s potential to drive economic and technological advancement. The administration’s forward-looking stance aimed to position nuclear power at the forefront of America’s energy future.
The event underscored Idaho’s role as a central hub for nuclear technology development, branding the state as the "beating heart" of the industry. Officials stressed that ongoing successes in these pilot projects will lead to new objectives, extending the nation’s nuclear renaissance beyond the current milestones.
