The federal government is sitting on a massive, terrifyingly radioactive inheritance from the Cold War. For decades, the plan for America's excess weapons-grade plutonium was simple, if incredibly expensive: mix it with dirt, encase it, and bury it deep inside a New Mexico desert. It was supposed to stay there forever.
The Trump administration just flipped that script. Read more on a connected issue: this related article.
The Department of Energy announced it is entering advanced negotiations with five private energy companies. The goal is to hand over up to 20 metric tons of highly volatile, weapons-grade plutonium from dismantled warheads so these startups can recycle it into commercial reactor fuel. If finalized, this marks the first time in United States history that private entities will get their hands on bomb-grade plutonium for commercial power.
It is an aggressive, high-stakes attempt to solve a crippling nuclear fuel shortage. But critics think it is absolute madness. More analysis by The New York Times explores comparable perspectives on this issue.
The Desperate Search for SMR Fuel
You cannot understand this sudden policy shift without understanding the massive roadblock facing the next generation of nuclear power. Tech giants and energy companies are desperate for electricity. Artificial intelligence data centers are chewing through power at a rate we haven't seen in decades.
Enter Small Modular Reactors, or SMRs. These smaller, high-tech reactors are supposed to be safer, cheaper, and quicker to deploy than those massive, dome-shaped nuclear plants built in the 1970s. Companies like Oklo—backed by tech elites and formerly featuring current Energy Secretary Chris Wright on its board—are racing to build them.
There is just one glaring problem. These advanced reactors cannot run on the low-enriched uranium used by traditional power plants. They need a highly concentrated, energy-dense fuel. Right now, the commercial supply chain for that fuel is practically nonexistent in the West.
Jacob DeWitte, the CEO of Oklo, calls the fuel supply constraints a key throttle on the industry. The Trump administration views this 20-metric-ton stockpile of surplus plutonium as a giant, forgotten asset sitting under the couch cushions. Instead of spending billions to bury it, they want to use it as a bridge fuel to get these advanced reactors online years ahead of schedule.
Who Gets the Cold War Plutonium
The Energy Department didn't just throw open the vault doors to anyone. They selected five companies to start negotiating the strict security and technical details of the Surplus Plutonium Utilization Program.
- Oklo Inc.: The high-profile startup partnering with European developer Newcleo, aiming to build fast-neutron reactors. Oklo says it's ready to invest up to $2 billion in domestic fuel-fabrication infrastructure.
- SHINE Technologies: A company focused on nuclear fusion and recycling technologies, aiming to solve the waste problem.
- Exodys Energy: A stealthier nuclear startup looking to capitalize on advanced fuel cycles.
- Standard Nuclear: Working on localized advanced reactor designs.
- Flibe Energy: A company focusing on molten-salt reactor technology, which can theoretically utilize alternative fuel types like plutonium.
The government isn't selling this material to make a quick buck. In fact, the draft plans indicate the plutonium will be handed over at little to no cost. But the catch is a logistical nightmare. The private sector has to foot the entire bill for transportation, designing the secure facilities, fabricating the fuel, and eventually decommissioning the recycling plants.
The Security Nightmare Experts Are Warning About
If this sounds like a great deal for the taxpayer, nonproliferation experts want you to take a step back and look at the terrifying security math.
Twenty metric tons of weapons-usable plutonium is an astronomical amount of material. According to a joint letter sent to the administration by Senator Ed Markey and Representatives Don Beyer and John Garamendi, that is enough raw material to manufacture roughly 2,000 nuclear bombs.
Plutonium is not like uranium. Uranium has to go through massive, easily trackable enrichment facilities to become bomb material. Plutonium is already there. If a rogue state or a highly organized terrorist group intercepts a shipment of this material during transit between private processing facilities, they have the core ingredient for an atomic weapon.
There is a reason the United States has historically banned the commercial use of weapons-grade plutonium. We have spent decades telling other nations not to reprocess or utilize plutonium in their civil energy sectors. Edwin Lyman, a nuclear physicist at the Union of Concerned Scientists, argues that the U.S. completely loses its moral authority to discourage global plutonium proliferation the second we hand our own warhead cores over to private startups.
Learning From a Fifty Billion Dollar Mistake
This is not the first time Washington has tried to turn swords into plowshares with this exact stockpile. Under a 2000 nonproliferation agreement with Russia, the U.S. committed to disposing of 34 metric tons of surplus plutonium by converting it into Mixed Oxide fuel, known as MOX.
The project was an unmitigated disaster.
The construction of the MOX fuel fabrication facility at the Savannah River Site in South Carolina turned into a legendary money pit. It suffered from constant design flaws, management failures, and skyrocketing expenses. By 2018, the first Trump administration officially killed the project after estimates showed it would cost taxpayers more than $50 billion to finish.
After that failure, scientists and officials under both the Biden and Trump administrations pivoted back to a simpler plan: dilute the plutonium with inert materials to ensure it could never be weaponized again, then bury it in the Waste Isolation Pilot Plant in New Mexico. That disposal route carried a projected price tag of around $19 billion to $20 billion over thirty years.
The new policy essentially bets that private tech startups can succeed where the federal government failed so spectacularly, all while shifting the multi-billion-dollar processing financial burden off the federal ledger.
What Happens Next
Do not expect plutonium-powered reactors to pop up overnight. Entering advanced negotiations is merely the first legal hurdle in a marathon of regulatory red tape.
If you are tracking the energy sector or looking to invest in the nuclear renaissance, watch these three specific milestones over the next twelve months:
- The Transport Protocols: Look for the Department of Energy to release the security guidelines for moving this material out of heavily fortified facilities like Los Alamos, Pantex, and Savannah River. The level of military escort required will tell you exactly how expensive this fuel will actually be to move.
- The Nuclear Regulatory Commission (NRC) Approvals: Private startups must obtain entirely new categories of commercial licenses to handle weapons-grade materials. Watch how fast the NRC processes Oklo and Newcleo's upcoming infrastructure applications.
- The Local Pushback: Watch the state governments of New Mexico, Texas, and South Carolina. Local communities have historically fought bitter legal battles over the transit and processing of high-level radioactive waste.
Turning the relics of the Cold War into clean electricity sounds like a beautiful, poetic solution to our modern grid crisis. But dealing with plutonium means playing with the most unforgiving element on the periodic table. The line between an energy revolution and a national security catastrophe has never been thinner.
