evidence: The analysis below reflects the status of Iran’s enrichment program as of August 17, 2024, the date of the latest estimates provided by the International Atomic Energy Agency (IAEA). Because Iran has reduced its cooperation with the Agency, the Agency is no longer able to precisely verify Iran's stockpile of enriched uranium at any one time. The Agency can verify uranium product that has been removed from the enrichment process, but it must rely on information provided by Iran to account for the amount that remains in-process. Because the in-process uranium represents a fraction of the total stockpile that is later verified, the estimates are suitable for use as a baseline measurement of how much enriched uranium Iran possesses. The analysis below is based on those estimates. [...] [3] The IAEA estimated that as of August 17, 2024, Iran's uranium stockpile contained 4,951.1 kg of uranium in the form of uranium hexafluoride (UF6), 164.7 kg of which was enriched "up to" a level of 60% in the fissionable isotope U-235, 813.9 kg of which was enriched "up to" a level of 20% U-235, and 2,321.5 kg of which was enriched "up to" a level of 5% U-235. The U-235 isotope makes up about .7% of natural uranium; its concentration can be increased, or enriched, using centrifuges.
