Hearing Analysis
Overview
This hearing focused on the Department of Energy's (DOE) progress in implementing four executive orders issued by President Trump in May 2025. These directives aim to catalyze a "nuclear renaissance" in the United States by accelerating the deployment of advanced reactors, reforming the Nuclear Regulatory Commission (NRC) licensing process, and securing a domestic nuclear fuel supply chain. The discussion centered on the urgent need for reliable, carbon-free baseload power to meet the skyrocketing energy demands of artificial intelligence (AI) data centers and reshored manufacturing, while simultaneously countering the global influence of Russia and China in the nuclear sector.
Key Testimony & Policy
Theodore J. Garrish, Assistant Secretary of Energy for Nuclear Energy, outlined four strategic pillars: reestablishing domestic uranium enrichment, fostering new reactor builds, expanding international exports, and completing the nuclear fuel cycle. He highlighted the critical need to replace Russian uranium imports, noting that $2.7 billion has been allocated to revitalize domestic enrichment capabilities. Garrish also discussed the Advanced Reactor Demonstration Program (ARDP), which supports public-private partnerships with companies like TerraPower and X-energy. He emphasized a shift in waste management strategy toward "nuclear life cycle innovation campuses" that prioritize recycling spent fuel rather than permanent burial, a move that would require updating the Nuclear Waste Policy Act of 1982.
Dr. John C. Wagner, Director of the Idaho National Laboratory (INL), reported on the laboratory's efforts to meet the President’s aggressive timeline of achieving criticality for at least three test reactors by July 4, 2026. He detailed progress on the DOME facility and the MARVEL test reactor, as well as the "Prometheus" project, which utilizes AI to accelerate reactor design and operation. Wagner advocated for legislative clarity regarding the DOE’s authorization authority for demonstration reactors on national lab sites to prevent regulatory overlap with the NRC. He also stressed the vulnerability of the High-Assay Low-Enriched Uranium (HALEU) supply chain, noting that no commercial-scale production currently exists outside of Russia and China.
Mike Laufer, CEO of Kairos Power, testified on the success of the milestone-based technology investment agreement modeled after NASA’s Commercial Orbital Transportation Services (COTS) program. This structure ensures federal funds are only disbursed upon the achievement of objective technical or regulatory goals. Laufer highlighted Kairos Power’s Hermes demonstration reactors in Tennessee and its commercial agreements with Google and the Tennessee Valley Authority (TVA). He urged Congress to expand the use of milestone-based funding to provide better value for taxpayers and greater agility for developers.
Notable Exchanges & Partisan Dynamics
The hearing demonstrated a high degree of bipartisan consensus regarding the necessity of nuclear energy for national security and economic competitiveness. Chairman Mike Lee (R-UT) and Ranking Member Martin Heinrich (D-NM) both emphasized the role of nuclear power in supporting the AI revolution. However, Sen. Heinrich expressed concerns regarding the administration's previous budget proposals that sought to cut nuclear energy funding by $400 million, questioning if the rhetoric of support matched the fiscal reality.
Sen. Catherine Cortez Masto (D-NV) focused heavily on the waste issue, seeking and receiving confirmation from Assistant Secretary Garrish that the administration remains opposed to the Yucca Mountain repository. She pushed for more details on how the proposed recycling campuses would handle waste streams from advanced reactors. Sen. Steve Daines (R-MT) and Sen. James E. Risch (R-ID) discussed the geopolitical implications of the nuclear supply chain, with Sen. Daines highlighting the "Trump Route for International Peace and Prosperity" (TRIPP) as a vital corridor for moving resources like uranium from Kazakhstan to Western markets, bypassing Russian and Chinese influence.

What's Next
The most immediate milestone is the July 4, 2026, target for three test reactors to achieve criticality. Additionally, states interested in hosting "nuclear life cycle innovation campuses" must submit their formal proposals to the DOE by April 1, 2026. Witnesses and senators indicated that legislative action will be required to update the Nuclear Waste Policy Act and to clarify DOE authorization authorities. The committee is also expected to continue work on the Advancing Research in Nuclear Fuel Recycling Act and the ARC Act, which aims to mitigate cost-overrun risks for first-of-a-kind commercial reactors.
Transcript
Committee will come to order. Good morning to everyone and welcome. Before turning to my opening statement, I want to let all members know how we're going to proceed this morning. I also want to thank Senator Heinrich and his staff for working with us on today's hearing. On May 23, 2025, President Trump issued four executive orders concerning nuclear energy to help launch a renaissance in that really important area and that increasingly important area within the energy sector of the United States. These executive orders do the following: direct deployment of advanced nuclear reactor technologies for national security; require needed reforms at the Nuclear Regulatory Commission to safely and expeditiously license nuclear facilities; employ existing Department of Energy authorities to accelerate nuclear reactor testing and the deployment of new designs; and direct comprehensive action to reinvigorate America's nuclear industrial base, secure supply chains, and prepare our workforce to ensure American nuclear energy dominance. Today the Senate Committee on Energy and Natural Resources will hear testimony regarding the U.S. Department of Energy's implementation of these orders from President Trump. We'll receive testimony from three eminently qualified experts. They are the Honorable Theodore Garrish, Assistant Secretary of Energy for Nuclear Energy; Dr. John Wagner, Director of the Idaho National Laboratory and President of Battelle Energy Alliance; and Dr. Mike Laufer, the co-founder and Chief Executive Officer of Kairos Power. On behalf of the committee, I welcome each of you to the committee today. For much of the past century, the United States operated from a position that most countries have never had. We had reliable energy. It allowed American industry to thrive. It allowed the economy to grow. It gave the United States a level of independence that few nations enjoy. Whenever that advantage has slipped, the consequences have been immediate. In the 1970s, supply disruption drove prices up and gave foreign producers leverage. Decisions made overseas began to overshape outcomes at home more than they had previously. Now for the first time in decades, we're confronting some of those same pressures again. The question is no longer how we use energy; it's whether we have enough of it. Data centers are not going to wait. Advanced manufacturing is not slowing down. The systems driving artificial intelligence don't just scale down when power is scarce. They go to where the electricity is. If we cannot meet that demand here, it will be met somewhere else. We can be sure of that. Because when energy tightens, everything downstream follows. This requires constant, large-scale, reliable energy. And that is where nuclear energy comes in. So today we're examining whether the United States is moving quickly enough to deploy the next generation of nuclear technologies. What has long been a stable and essential part of our energy mix is becoming central to whether we can meet this demand at all. We are already seeing energy-intensive industries turn toward nuclear as a long-term solution. Russia and China both understand this. They're building reactors at scale. They're financing and exporting them across the world. They're locking in fuel supplier arrangements that tie countries to their technology and their influence for decades. To put it bluntly, energy will determine the global balance of power for the next generation. And if we hesitate now, we will not just fall behind; we'll be operating inside a system defined by others, dependent on supply chains and standards that we didn't write. That is not a position of strength and it's not a position that the United States can accept. So the question before us is no longer whether nuclear energy will play a role in our future; it's how much capacity we can build and how quickly we can build it. Recognizing that urgency, President Trump issued four executive orders last May to elevate the American energy industry to the next level. These orders build on previous work that's been done in Congress, bipartisan work that's been done on some of these issues. They focus on modernizing the regulatory framework, accelerating reactor testing, enabling deployment for national security applications, and rebuilding the domestic nuclear industrial base. At least three test reactors will achieve criticality by July 4 of this year. A microreactor will be deployed at a military installation by 2028. Ten new large reactors will be under construction by 2030. The Department of Energy has already begun implementing these directives, including standing up new programs and expanding the use of its existing authorities. In coordination with Idaho National Laboratory, it has rolled out initiatives such as the reactor and fuel line pilot programs to support advanced reactor development and deployment. Today's hearing provides an opportunity to examine that execution, assess programs, identify remaining barriers that we still face, and determine what additional actions may be necessary to ensure that the United States leads in nuclear energy technology. We're joined by witnesses who are directly involved in implementing and advancing these efforts and I look forward to hearing from them. I now recognize my friend and colleague, the ranking member, Senator Heinrich, for his opening remarks.
