3. On 30 August 2022, Iran informed the Agency that on 29 August 2022 it had started feeding the second IR-6 cascade with UF6 enriched up to 2% U-235 for the production of UF6 enriched up to 5% U-235. On 31 August 2022, the Agency verified at FEP that Iran was feeding the two IR-6 cascades with UF6 enriched up to 2% U-235 for the production of UF6 enriched up to 5% U-235; and that the third IR-6 cascade had not been fed with nuclear material.
