The UN atomic watchdog said Friday that Iran was continuing to breach the limitations set by the 2015 nuclear deal with major powers and increasing its stock of enriched uranium and refining it to a greater purity than allowed. In a confidential quarterly report distributed to member states and seen by The Associated Press, the International Atomic Energy Agency said Iran said Iran continues to enrich uranium up to 4.5%, above the 3.67% allowed. The violations were announced by Iran, and confirmed by the IAEA last month, and are meant to put pressure on the signatories to the deal, known as the Joint Comprehensive Plan of Action (JCPOA), to provide more economic incentives. Enriched uranium at the 3.67% level is enough for peaceful pursuits but is far below weapons-grade levels of 90%. At the 4.5% level, it is enough to help power Irans Bushehr reactor, the countrys only nuclear power plant. The nuclear deal is meant to keep Tehran from building atomic weapons in exchange for economic relief. It has been complicated by the unilateral withdrawal of the United States from the deal last year and Washingtons increased sanctions, which have been taking a toll on the Iranian economy. That has left the other signatories — Germany, Britain, France, Russia and China — struggling to come up with enough incentives to keep Iran in the deal. So far, the major powers in the deal have expressed concern about Tehrans violations and urged the country to return to the limitations set in the agreement but havent taken further action. Britain, France and Germany have set up a complex barter-type system dubbed INSTEX that aims to protect companies doing business with Iran from American sanctions. The first transactions through this system are being "processed," but have not yet been completed, EU foreign policy chief Federica Mogherini said Friday. Under the weight of those sanctions, the value of Irans currency has plummeted by about 60% in the last year. Inflation is up 37% and the cost of food and medicine has soared 40% to 60%, according to EU figures. The Europeans hope that the possibility, however slight, of a high-level meeting between US President Donald Trump and Iranian President Hassan Rouhani might help keep Iran in the deal. "If this new momentum is real, this can build on the work that we have been doing all these years and will continue to do in these days and months and weeks to preserve the JCPOA," Mogherini said before the IAEA report. "The two things are not alternatives. The two things might be complementary." In Fridays report, the IAEA said that Iran has continued to permit its inspectors to monitor its nuclear facilities and has also remained under the limit of 130 tons (143.3 US tons) set on its stockpile of heavy water, with 125.5 tons (138.34 US tons) stockpiled. It said Irans stock of low-enriched uranium hit 241.6 kilograms (532.64 pounds) as of August 19. The JCPOA cap is 202.8 (447.1 pounds) kilograms of enriched uranium. The stockpile is made up of 216.5 kilograms (477.3 pounds) of uranium enriched up to 3.67%, and 25.1 kilograms (55.34 pounds) of uranium enriched up to 4.5%, the IAEA reported. In its previous quarterly report, it noted that Iran had installed "up to 33" more advanced IR-6 centrifuges, used to enrich uranium and that 10 had been tested. Under terms of the nuclear deal, Iran is allowed to test no more than 30 of the IR-6s once the deal has been in place for eight and a half years. The deal is murky about limits before that point, which will arrive in 2023. In the current report it repeated that Iran had installed "up to 33" of the IR-6 centrifuges, but said 11 have now been tested, and that "technical discussions in relation to the IR-6 centrifuges are ongoing." Iran has threatened to take further steps by September 6, such as enriching to 20% or restarting mothballed centrifuges, machines that enrich uranium. The report also hinted at less than ideal cooperation from Iran, saying: “Ongoing interactions between the Agency and Iran ... require full and timely cooperation by Iran. The Agency continues to pursue this objective with Iran.”
