Iran has also started to dismantle uranium enrichment centrifuges at its Natanz and Fordow nuclear facilities, the IAEA report states. Under the deal with major powers reached in July, Iran is supposed to reduce the number of centrifuges it has in operation.
Under the Joint Comprehensive Plan of Action signed between Iran and a US-led group of six countries in July of 2015, Iran must reduce its stockpile of low-enriched uranium to 300 kilograms in order for the nuclear agreement to fully go into effect - a total that does not count uranium contained in fuel rods for the country's nuclear reactor. According to an August IAEA report, Iran has 7,845 kilograms of low-enriched uranium.
The Reuters report comes just a month after Iranian Supreme Leader Ali Khamenei appeared to unilaterally alter the timeline for Iran meeting its obligations under the JCPOA.
On October 21st, Khamenei, who is the country's highest political and spiritual authority under Iran's theocratic system of government, announced that Iran would not begin exporting its enriched uranium in order to reach the 300 kilogram limit until the IAEA had completed its investigation of Iran's past nuclear weaponization work, an inquiry that won't officially end until the agency issues a report in December.
Additionally, Khamenei announced that export wouldn't begin until "a reliable firm contract for it and adequate guarantees for its execution is signed."

The growth of Iran's uranium stock wouldn't be the only recent piece of mixed news for the JCPOA. On October 11th, Iranian state media announced that the country had tested a new model of the Emad missile, a mid-range ballistic missile with the ability to deliver a nuclear warhead. The test violated a UN resolution that will be repealed once the JCPOA officially goes into effect.
Iran also released five high-value al Qaeda prisoners in September, including the interim head of the global terrorist network following the May 2011 death of Osama bin Laden. Washington Post journalist Jason Rezaian, a US-Iranian dual citizen, was convicted of espionage by a secret court in October, while Iranian-American businessman Siamak Namazi was arrested in Tehran in mid-October.
