Enrichment, Enrichment R&D, Stockpiles
• Iran’s long term plan includes certain agreed limitations on all uranium enrichment and uranium enrichment-related activities including certain limitations on specific research and development (R&D) activities for the first 8 years, to be followed by gradual evolution, at a reasonable pace, to the next stage of its enrichment activities for exclusively peaceful purposes.
• Iran will begin phasing out its IR-1 centrifuges in 10 years. During this period, Iran will keep its enrichment capacity at Natanz at up to a total installed uranium enrichment capacity of 5060 IR-1 centrifuges. Excess centrifuges and enrichment-related infrastructure at Natanz will be stored under IAEA continuous monitoring.
(Note: Iran currently has about 19,000 IR-1 and advanced IR-2M centrifuges installed)
--
Based on its long-term plan, for 15 years, Iran will keep its level of uranium enrichment at up to 3.67%.
(Note: Prior to the Joint Plan of Action, Iran enriched uranium to near 20%)
-- Iran will refrain from any uranium enrichment and uranium enrichment R&D and from keeping any nuclear material at Fordow for 15 years.
(Note: Iran currently has about 2,700 IR-1 centrifuges installed at Fordow of which about 700 are enriching uranium)
• Iran will convert the Fordow facility into a nuclear, physics and technology center.
• 1044 IR-I machines in six cascades will remain in one wing at Fordow. Two of those six cascades will spin without uranium and will be transitioned, including through appropriate infrastructure modification, for stable isotope production. The other four cascades with all associated infrastructure will remind idle.
• During the 15 year period, Iran will keep its uranium stockpile under 300 kg of up to
3.67% enriched UF6 or the equivalent in other chemical forms.
(Note: Iran currently maintains a stockpile of about 10,000 kg of low-enriched UF6)
-- All other centrifuges and enrichment-related infrastructure will be removed and stored under IAEA continuous monitoring.
