Reshuffles Nonproliferation Program” reported that the Department of Energy’s Foreign Research Reactor Spent Nuclear Fuel Acceptance Program had retrieved 485 kilograms of U.S.-origin highly enriched uranium from abroad. The correct figure is 1,100 kilograms. The 485 kilograms is the amount of U-235 retrieved. An Energy Department official provided Arms Control Today with the original, incorrect data.

In the May 2004 issue, the article “Iran and IAEA Agree on Action Plan; U.S., Europeans Not Satisfied” reported that an official from Iran’s Atomic Energy Organization told Reuters April 12 that Iran had stopped making gas centrifuge components 30 days earlier.
