The Trump administration is considering a proposal to divert plutonium that plays a central role in the U.S. nuclear weapons stockpile to fuel a new generation of power plants, according to an Energy Department official and previously undisclosed department documents.
The proposal calls for the department to alter the plutonium so it can be used by civilian power companies, including startups pitching advanced reactor designs. It’s part of a broader push by President Donald Trump to convert tons of the Energy Department’s plutonium to civilian use, a notion that some lawmakers argue would undermine the U.S. weapons program for the benefit of untested private companies.
The initiative would involve harvesting plutonium on a large scale: According to a department official and a July 31 DOE memo seen by POLITICO, more than a fifth of the plutonium needed to meet Trump’s mandates would come from the highly radioactive spheres manufactured for the cores of nuclear weapons. DOE already faces a crunch to make more of those spheres, known as plutonium pits — it’s lagging behind Congress’ demands that it boost pit production to modernize the country’s nuclear deterrence.
The department is “not meeting the current pit manufacturing schedule,” said a former DOE official who is familiar with the department’s plutonium reserves. “So to make pit plutonium available would be a huge shift, and I’d be shocked.”
