The International Atomic Energy Agency (IAEA) circulated a report on 4 June declaring it has lost track of Iran's 440.9 kg stockpile of 60%-enriched uranium after 97 days without inspector access. Director General Rafael Grossi told the Associated Press that roughly 200 kg is probably at Isfahan, leaving about 240 kg with no confirmed location.
President Trump claims the uranium is 'entombed', but the IAEA cannot verify that. Any deal clause requiring Iran to hand over the stockpile would cover material nobody outside Iran can currently count or locate.
