U.S. Seeks to Give Weapons-Grade Plutonium to Start-Ups for Fuel

scienceMay 26, 202633365

The Biden administration proposed transferring Cold War weapons-grade plutonium from Energy Department stockpiles to private reactor startups to be fabricated into reactor fuel. The plan would let companies developing advanced and experimental reactors convert plutonium into test and commercial fuel, marking a break from long-standing federal custody rules for surplus bomb material. Proponents say using the plutonium could speed commercial demonstrations and reduce long-term storage costs; critics say moving weapons-usable material into private hands increases proliferation, safety, and regulatory risks. The decision could reshape the nuclear industry by unlocking a large fuel source while forcing tighter safeguards and international scrutiny.
