Iran's stockpile of enriched uranium now stands at more than ten times the limit set down in a 2015 nuclear deal with world powers as it continues to use more advanced centrifuges to enrich uranium than permitted, the International Atomic Energy Agency said in a report on Friday. According to the IAEA report, Iran's enriched uranium stockpile has reached 2,105 kilograms. Iran signed the nuclear deal in 2015 with the United States, Germany, France, Britain, China and Russia. Known as the Joint Comprehensive Plan of Action, the deal allows Iran only to keep a stockpile of 202.8 kilograms (447 pounds). Iran insists its nuclear program is exclusively for peaceful purposes. It comes after Iran gave IAEA inspectors access to one of two suspected former nuclear sites. "Iran provided Agency inspectors access to the location to take environmental samples," IAEA said in the report. "The samples will be analyzed by laboratories that are part of the Agency's network," it added. One diplomatic source said the results of this analysis could take up to three months. An inspection at the second site will take place "later in September 2020," the report said. Iran had denied the agency access earlier this year, prompting the IAEA's board of governors to pass a resolution in June urging Tehran to comply with its requests. Tehran announced last week it would allow the IAEA access to the two sites, following a visit by IAEA Director General Rafael Grossi. — Agencies
