Agreement details

According to the joint statement in Switzerland, the P5+1 countries and Iran agreed on a framework for a deal. According to this framework, Iran would redesign, convert, and reduce its nuclear facilities and accept the Additional Protocol (with provisional application) in order to lift all nuclear-related economic sanctions, freeing up tens of billions of dollars in oil revenue and frozen assets. In addition to the joint statement, the United States and Iran issued fact sheets of their own.


The joint statement

The joint statement outlines the following:


Enrichment

* Iran's enrichment capacity, enrichment level and stockpile will be limited for specified durations. * There will be no enrichment facilities other than Natanz. * Iran is allowed to conduct research and development on centrifuges with an agreed scope and schedule. * Fordo, the underground enrichment center, will be converted to a "nuclear, physics and technology centre".


Reprocessing

* The heavy water facility in Arak with help of international venture will be redesigned and modernized to "Heavy Water Research Reactor" with no weapon grade plutonium byproducts. * The spent fuel will be exported, there will be no reprocessing.


Monitoring

* Implementation of the modified Code 3.1 and provisional application of the Additional Protocol. * Iran agreed

Other listed parameters and reactions by the United States and Iran

In addition to the final statement, both the United States and Iran have made public more detailed descriptions of their agreement. Officials of both sides acknowledge that they have different narratives on this draft. The U.S. government has published a fact sheet summarizing the main points of the deal. Shortly after it was published, top Iranian officials, including the Iranian supreme leader and the Iranian minister of defense have disputed the document on key points which remain unresolved.

, Iran's deputy foreign minister who led the negotiations, made an announcement on state-controlled television that the recently reached nuclear deal with the world powers did not include limitations on Iran's weapons capabilities or missile power and that Tehran would keep arming its regional allies. "We have told them he P5+1 world powersin the negotiations that we will supply arms to anyone and anywhere necessary and will import weapons from anywhere we want and we have clarified this during the negotiations," Araghchi said.The Times of Israel, 22 July 2015, Iran’s deputy FM: We told world powers we’ll keep arming our allies, http://www.timesofisrael.com/irans-deputy-fm-we-told-world-powers-well-keep-arming-our-allies/ In a speech the following Saturday, Iran's Supreme Leader Ayatollah Ali Khamenei added, "Our policy will not change with regards to the arrogant US government."


Enrichment

According to details of the deal published by the US government, Iran's uranium stockpile will be reduced by 98% to 300 kg (660 lbs) for 15 years. The level of enrichment must also remain at 3.67%. Iran will retain no more than 6,104 out of almost 20,000 centrifuges it possesses. There are two uranium enrichment facilities in Iran— Natanz and Fordo. Under the Joint Comprehensive Plan of Action (JCPOA) agreed on 14 July, the Natanz facility will be limited to installing no more than 5,060 of the oldest and least efficient centrifuges for 10 years. At Fordo, no enrichment will be permitted for 15 years, and the underground facility will be converted into a nuclear, physics and technology centre. 1,044 centrifuges at the site will produce radioisotopes for use in medicine, agriculture, industry and science. This level of enrichment, 3.67%, would be enough just for peaceful and civil use to power parts of country and therefore is not sufficient for building a nuclear bomb. According to press TV report based on Joint Comprehensive Plan of Action (JCPOA), Iran's extra centrifuges and the related infrastructure in the Natanz facility will be collected by the International Atomic Energy Agency (IAEA) in order to be replaced by new machines consistent with the allowed standards. Iran will be allowed to allocate the current stockpile of enriched materials for the purpose of producing nuclear fuel or swapping it with uranium in the international markets. These comprehensive solutions permit Iran to continue its enrichment program inside its territory and also allowed to continue its production of nuclear fuel for running its nuclear power plants.


Fordo

According to the U.S. State Department fact sheet and a joint statement by Iran and the EU, Iran has agreed to convert its underground Fordo facility into a research centre for nuclear science and physics and about half of the Fordo facility would be dedicated to advanced nuclear research and production of stable radioisotopes which have important applications in medicine, agriculture, industry and science. Furthermore, Iran would maintain no more than 1,044 centrifuges for this purpose.


Sanctions

According to Press TV, the implementation of JCPOA followed by lifting of all the UN Security Council sanctions as well as all economic and financial embargoes by the United States and the European Union imposed on Iran's banks, insurance, investment, and all other related services in different fields, including petrochemical, oil, gas and automobile industries will be immediately lifted all at once. However, according to the fact sheet which is published by the U.S. government, U.S. and EU nuclear-related sanctions will be suspended after the IAEA has verified the implementation of the key nuclear-related steps by Iran.


Inspections and transparency

Iran will be required to provide the

access to all of its declared facilities so that the agency can be assured of the peaceful nature of the nuclear program. According to details of the deal published by the U.S. government, IAEA inspectors would have access to all of the nuclear facilities including enrichment facilities, the supply chain that supports the nuclear program and uranium mines as well as continuous surveillance at uranium mills, centrifuge rotors and bellows production and storage facilities. Iran will be required to grant access to the IAEA to investigate suspicious sites or allegations of a covert enrichment facility, conversion facility, centrifuge production facility, or yellowcake production facility anywhere in the country. Iran will implement an agreed set of measures to address the IAEA's concerns regarding the Possible Military Dimensions (PMD) of its program. According to the Iranian fact sheet, Iran will implement the Additional Protocol temporarily and voluntarily in line with its confidence-building measures and after that the protocol will be ratified in a time frame by the Iranian government and parliament (Majlis).
