Valar Atromics has been selected by the U.S. Department of Energy to achieve criticality on American soil by July 4, 2026, a milestone intended to advance the nation's nuclear energy capabilities pursuant to Executive Order 14301. The achievement follows a historic military airlift of a nuclear microreactor into Utah, marking a significant step in the federal push for accelerated nuclear power deployment.
DOE goals for rapid deployment
The Department of Energy (DOE) recently announced that three small reactors are expected to be running by July 4, a development involving officials including Energy Secretary Chris Wright. This push for rapid deployment is part of a broader effort to meet the energy needs of emerging technologies, such as artificial intelligence, through what proponents call 'Nuclear Gigasites.'
Advancing national nuclear science
According to the Department of Energy's Office of Nuclear Energy, the agency continues to work toward advancing nuclear energy science and technology to address national energy, environmental, and economic requirements. The office is specifically focused on enabling the deployment of advanced nuclear reactors and maintaining U.S. leadership in nuclear energy technology.
Local support in Utah
The arrival of Valar Atomics' Ward-250 test reactor in Utah has garnered significant local support. The Emery County Commission previously approved a letter of support for the company as the reactor arrived in the Castle Country region.
Historic military airlift details
As reported by Valar Atomics, the transport of the 5-megawatt nuclear reactor to Utah involved a partnership between Dow and the Department of Energy. The delivery was executed via a first-of-its-kind mission using a U.S. Air Force C-17 Globemaster III aircraft, which airlifted the microreactor across three different states.
Broader nuclear industry trends
The deployment of this technology is part of a larger 'nuclear renaissance' described by industry observers. The Department of Energy has been actively seeking to transform surplus plutonium into nuclear fuel and has announced various loans for the American nuclear supply chain.
Technical milestones and community engagement
Valar Atomics has also reached significant technical milestones, including achieving cold criticality at Los Alamos National Laboratory (LANL) during its Project NOVA mission in Nevada. The company's recent activities include hosting community open houses to provide the public with a glimpse of the Ward-250 test reactor facility.
The company's expansion has been supported by significant capital investment. Valar Atomics recently announced a $130 million Series A funding round to scale its nuclear fission operations. The startup, which originated in El Segundo, is positioning itself as a key player in solving the energy crisis posed by the rapid growth of AI.
In addition to technical milestones, the company has engaged in legal and regulatory challenges, including a lawsuit against the Nuclear Regulatory Commission (NRC). This litigation follows the company's stated commitment to addressing nuclear necessity and regulatory hurdles.
As the July 4, 2026, deadline for criticality approaches, the focus remains on the viability of deployable microreactor technology. The Department of Energy continues to oversee various advanced reactor research and development programs, including the Advanced Reactor Demonstration Program, to ensure the continued operation and deployment of safe, efficient nuclear energy across the United States.
