Trump Administration Proposes Transferring Cold War Plutonium to Nuclear Startups for Clean Energy Projects

The Trump administration has identified multiple nuclear startups as potential recipients of Cold War-era plutonium stockpiles, aiming to repurpose military-grade radioactive material for civilian nuclear reactors. Five companies, including Franco-Italian nuclear reactor specialist Newcleo, are entering advanced negotiations with US authorities to access portions of the 99 tons of plutonium stored at secure facilities nationwide.

The selected companies must demonstrate their ability to safely handle and transport highly radioactive material that poses significant security risks. While the plutonium was produced for nuclear weapons through the early 1990s, officials hope converting it into reactor fuel could address both disposal challenges and growing energy demands.

Legacy Stockpile Challenges

In May 2025, President Trump revitalized efforts to utilize plutonium stockpiles following decades of failed disposal attempts. “Storing them costs money and requires continuous security measures to prevent container corrosion,” explained Noah Mayhew, a nuclear governance specialist at the Vienna Center for Disarmament and Non-Proliferation.

Post-Cold War initiatives to convert plutonium into energy were abandoned during Obama’s second term. Former President Biden pursued a New Mexico burial project that stalled due to cost and complexity. Trump’s approach differs by engaging private sector solutions to address the administration’s nuclear renewal objectives.

Geopolitical and Energy Motivations

AI-driven computing demands and recent disruptions in Russian uranium supplies have influenced the policy shift. “US nuclear expansion aims to reduce dependence on Russian enriched uranium while meeting AI industry energy requirements,” noted Mayhew.

Critics question whether plutonium conversion offers practical advantages over traditional uranium enrichment. “Converting plutonium into energy is costly and time-intensive, with first kilowatt-hour production potentially taking decades,” explained physicist Moritz Kütt of Hamburg Nuclear Disarmament Laboratory.

The proposal raises proliferation concerns, as separated plutonium requires fewer steps for weaponization compared to uranium enrichment. “A quantity roughly the size of a melon could theoretically produce nuclear explosive devices,” warned Mycle Schneider of the World Nuclear Industry Status Report.

Security and Oversight Concerns

Currently secured at fixed facilities, plutonium stockpiles would face increased transport risks if privatized. “Expanded handling personnel and movement routes elevate theft and loss probabilities,” warned Chris Spedding of University of Leicester’s Leverhulme Centre for Humanity in Space.

International oversight through agencies like the International Atomic Energy Agency may help ensure security protocols. However, critics argue the initiative sends negative signals about US commitment to nuclear disarmament.

“Transferring weapons-usable material to private entities undermines non-proliferation messaging,” stated Mayhew. Other nations may interpret similar plutonium utilization as acceptable precedent.

Conflict of Interest Questions

Democratic Senator Edward Markey has raised concerns about Energy Secretary Chris Wright’s prior relationship with Oklo, a company potentially benefiting from the program. “The administration may prioritize Oklo’s financial interests over national security considerations,” Markey wrote in a letter to Trump.

Observers suggest the initiative primarily serves public relations purposes, potentially helping startups attract investor funding through perceived government backing.
