Trump Administration Offers Cold War Plutonium to Private Nuclear Companies
Finn's Take· TL;DR- Trump administration selected five companies, including Oklo Inc., to access 20 metric tons of surplus weapons-grade plutonium from dismantled warheads for advanced nuclear reactor fuel.
- Advanced nuclear companies face fuel supply bottlenecks limiting deployment; repurposing Cold War plutonium could provide bridge fuel and reduce dependence on foreign uranium sources like Russia.
- Democratic lawmakers warn the program poses nuclear proliferation risks, potentially providing material for thousands of weapons, and may set precedent for other countries' civilian weapons-grade material use.
Historic Nuclear Deal Takes Shape
The Energy Department announced Tuesday it had selected advanced nuclear company Oklo Inc, as well as four other companies, to begin "advanced negotiations" over whether the companies could access its Surplus Plutonium Utilization Program . This significant new deal in the works could allow five private companies to access weapons-grade plutonium for the first time — and convert it into electricity .
The Trump administration plans to make about 20 metric tons of plutonium from dismantled nuclear warheads available to U.S. power companies . The plutonium is currently stored in high-security facilities in Texas, New Mexico and South Carolina , where it has a half-life of 24,000 years and must be handled with protective gear .
President Donald Trump last May ordered the halt of much of a program to dilute and dispose of surplus plutonium, and instead provide it as a fuel for advanced nuclear technologies . Prior to pursuing a strategy of repurposing old plutonium for nuclear power fuel, the Biden administration's Energy Department and National Nuclear Security Administration had been pursuing a different strategy — seeking to dilute and bury the plutonium deep underground in New Mexico .
Nuclear Renaissance Meets Fuel Shortage
Some advanced nuclear companies are backed by big tech; there's a huge demand for their future power, as artificial intelligence greatly increases US electricity demand. However, their current bottleneck is fuel . Oklo co-founder and CEO Jacob DeWitte said fuel supply limits remain one of the biggest obstacles facing advanced reactor deployment. "This program creates a pathway to use existing surplus material as bridge fuel for advanced reactors to bring more reactors online sooner" .
At NNSA facilities, nuclear scientists have been making advanced reactor fuel — a process that creates a molten soup of weapons-grade uranium combined with low-enriched uranium, all mixed in a massive, metal cauldron heated to around 2,500 degrees Fahrenheit . Oklo plans to develop this fuel with the support of the European firm newcleo, which specializes in advanced reactors .
Until Russia launched its war with Ukraine in 2022, it had been the primary supplier of enriched uranium to the US . Material that has been set aside for disposal can instead be converted into fuel to produce electricity , reducing America's dependence on foreign fuel sources.
Security Concerns and Political Pushback
Several Democratic lawmakers have warned of nuclear proliferation risks, estimating that the quantities of plutonium involved could be sufficient to manufacture up to 2,000 atomic weapons . Critics warn the move could increase nuclear proliferation risks by setting a precedent for civilian use of weapons-grade material .
A potential plutonium deal with the Trump administration, if successful, could be a major step forward for advanced nuclear companies building small modular reactors, which are racing to obtain fuel for their power-making operations. But it could also spur concerns about nuclear proliferation, and the US cracking the door open for other countries to do the same .
U.S. Energy Secretary Chris Wright was on Oklo's board of directors before joining Trump's cabinet , raising questions about potential conflicts of interest in the selection process.
The Nuclear Future
The negotiations represent a dramatic shift in how America handles its nuclear legacy. Rather than treating weapons-grade plutonium as waste requiring expensive disposal, the Trump administration sees it as a valuable resource for powering the next generation of clean energy. Oklo, whose stock price was up more than 5.5% to $69.51 per share, said it plans to develop the fuel with newcleo, a European company that aims to build high-tech nuclear reactors .
This approach could accelerate America's nuclear renaissance while addressing two pressing challenges: securing domestic fuel supplies and managing dangerous Cold War-era materials. Whether these benefits outweigh the proliferation risks will likely determine the program's ultimate success and shape nuclear policy for decades to come.
