US Resumes Large-Scale Production of Plutonium Pits for Nukes
During the Cold War, the US produced thousands of “plutonium pit” detonators at the Rocky Flats Plant in Colorado. Production halted in 1989 after the FBI and the EPA uncovered massive violations of environmental regulations. A small handful of pits has since been produced at the Los Alamos National Laboratory in New Mexico.
