According to a confidential International Atomic Energy Agency (IAEA) report, Iran has taken the first step in converting 2.1 kilograms of its 60%-enriched uranium into a form used for medicine. The isotope that will result once the process is completed, molybdenum-99, cannot be processed further into nuclear fuel. Iranian media outlet Mehr News publicly reported the conversion. The IAEA estimated Iran's stockpile of 60%-enriched uranium to be 33.2 kilograms as of February 19.
