Iran's stockpile of low-enriched uranium was reduced by 97 percent, from 10,000 kg to 300 kg.[68] This reduction will be maintained for fifteen years.[50][69][70][71] For the same fifteen-year period, Iran will be limited to enriching uranium to 3.67%, a percentage sufficient for civilian nuclear power and research, but not for building a nuclear weapon.[69][70][72] However, the number of centrifuges is sufficient for a nuclear weapon, but not for nuclear power.[73] This is a "major decline" in Iran's previous nuclear activity; prior to watering down its stockpile pursuant to the Joint Plan of Action interim agreement, Iran had enriched uranium to near 20% (medium-enriched uranium).[69][70][71] These enriched uranium in excess of 300 kg of up to 3.67% will be down blended to natural uranium level or be sold in return for natural uranium, and the uranium enriched to between 5% and 20% will be fabricated into fuel plates for the Tehran Research Reactor or sold or diluted to an enrichment level of 3.67%. The implementation of the commercial contracts will be facilitated by P5+1. After fifteen years, all physical limits on enrichment will be removed, including limits on the type and number of centrifuges, Iran's stockpile of enriched uranium, and where Iran may have enrichment facilities. According to Belfer, at this point Iran could "expand its nuclear program to create more practical overt and covert nuclear weapons options".[67][74]
For ten years, Iran will place over two-thirds of its centrifuges in storage, from its current stockpile of 19,000 centrifuges (of which 10,000 were operational) to no more than 6,104 operational centrifuges, with only 5,060 allowed to enrich uranium,[50][69] with the enrichment capacity being limited to the Natanz plant. The centrifuges there must be IR-1 centrifuges, the first-generation centrifuge type which is Iran's oldest and least efficient; Iran will give up its advanced IR-2M centrifuges in this period.[48][70][71] The non-operating centrifuges will be stored in Natanz and monitored by IAEA, but may be used to replace failed centrifuges.[75][76] Iran will not build any new uranium-enrichment facilities for fifteen years.[69]
