evidence: Iran’s stockpile of 60 percent HEU was 121.5 kg (U mass) or 179.7 kg uranium hexafluoride mass (hex mass) as of February 10, 2024, a decrease of 6.8 kg (U mass) since October 2023. [...] As of February 10, 2024, Iran had an IAEA-estimated stock of 712.2 kg of 20 percent enriched uranium (U mass and in the form of UF6), equivalent to 1053.6 kg (hex mass), representing an increase of 145.1 kg from 567.1 kg (U mass). Iran also had a stock of 31 kg (U mass) of 20 percent uranium in other chemical forms. [...] Despite the increase during this reporting period in the amount of uranium enriched between two and five percent, Iran has not prioritized stockpiling this material. For example, it has not made planned progress on the Enriched Uranium Powder Plant, a key civil facility to convert less than 5 percent enriched uranium hexafluoride into a uranium oxide powder for use in nuclear power reactor fuel. These two choices are at odds with Iran’s contention that its primary goal is to accumulate 4-5 percent enriched uranium for use in nuclear power reactor fuel. Instead, Iran has used this stock extensively to produce near 20 percent and 60 percent enriched uranium, far beyond Iran’s civilian needs.
