U.S. to gift Plutonium-239 to private nuclear industry

The Trump Administration’s trafficking of nuclear weapons-grade usable plutonium would significantly increase the global proliferation of nation state-sponsored nuclear weapon programs as well as the nuclear weapons material acquisition by thief and purchase for acts of nuclear terrorism.

Trump Administration’s give away of 20 MT of US plutonium weapons stockpile to private companies threatens nuclear proliferation

According to previously unreleased government documents obtained and reviewed by Politico and addressed in a letter from three Democrat members of Congress to President Donald Trump, The White House is preparing to give away 20 metric tons of weapons-usable plutonium to new nuclear start companies. The Trump deal calls for the equivalent of 2000 nuclear bombs previously slated for permanent disposal as nuclear waste) from the nation’s Cold War era nuclear weapons stockpile to be freed up to help jump start privately-owned U.S. commercial nuclear startup companies. The fledgling nuclear companies would instead use the plutonium fuel in a still unproven and unlicensed new generation of nuclear power plants for domestic power production. The plan includes U.S. startups to reprocess plutonium used in nuclear fuel for international export. The Trump Administration’s trafficking of nuclear weapons-grade usable plutonium would significantly increase the global proliferation of nation state-sponsored nuclear weapon programs as well as the nuclear weapons material acquisition by thief and purchase for acts of nuclear terrorism.

The White House proposal calls for the U.S. Department of Energy (DOE), currently charged with the nation’s nuclear weapons development and nuclear power promotion, to “alter” the military-grade plutonium so it can be used as fuel by civilian startup power companies in new reactor designs. Theses unfinished and yet to be approved designs (such as the sodium cooled metal fuel fast reactors “Aurora” by the Santa Clara, CA start-up Oklo, Inc.’s and Bill Gates’ TerraPower’s “Natrium”) are already being privately marketed for the domestic and international export of fast reactors by companies such as Oklo.

The White House Executive Orders originally issued in May 2025 as part of the President Trump’s national call to “Unleash Nuclear Energy” had directed that the US Department of Energy draw down the from the nation’s plutonium surplus. The current White House plan now additionally includes the military to civilian utility transfer of reserve warhead parts known as “plutonium pits.

The Politico article quotes Oklo’s CEO Jacob DeWitte, “Oklo, wants to take advantage of the plutonium fuel program. Unlike its competitors, Oklo’s fast-neutron reactors can use plutonium as a ‘bridge’ fuel to get around the bottlenecks that exist in obtaining the more desirable grades of uranium.” Those “desirable grades of uranium” fuel are currently only commercially available from the Russia global monopoly on High Assay Low Enriched Uranium (HALEU) which is just less than 20% enriched U-235.

Oklo’s prestigious former board member, Chris Wright, stepped down from the company when he was confirmed to be President Trump’s new Secretary of Energy. Oklo’s Aurora reactor design now under review by the U.S. Nuclear Regulatory Commission is a controversial liquid sodium-cooled metal fueled fast reactor. The fast reactor design is controversial chiefly because it can be retrofitted as a “dual purpose” (military and commercial) reactor to breed more plutonium for nuclear weapons and commercial power generation.

The concept for Oklo’s plan was opposed in a July 25, 2025 letter to Congress signed by 17 scientific experts on global non-proliferation of nuclear weapons. First and foremost, nothing has fundamentally changed to break with the five decades that the United States has opposed from using plutonium fuel in commercial power plants due to security and economic concerns. Their letter further pronounces that authorizing funds for the proposed civilian use of nuclear weapons-usable plutonium as fuel in nuclear power plants will only accelerate the global spread of nuclear weapons in two obvious ways; 1) US companies plan to internationally export plutonium fuel and the plutonium extraction technology, and; 2) the US cannot discourage other countries from further trafficking of weapons-usable plutonium as civilian nuclear fuel if the US is doing it ourselves.

Moreover, pyro-processing or “recycling” to extract plutonium and uranium for reuse as reactor fuel has already proven to be unsustainable economically and will only deepen the already bad economics of nuclear power. The processing is acknowledged as “very costly, due to safety and security concerns, both to extract from nuclear waste and to fabricate into fuel.”
