evidence: ISIS calculates from the IAEA report that in November 2015, Iran had a total inventory of low-enriched uranium comprising 8.3 tonnes of 3.5% uranium hexafluoride (5.57 tU) and 4.3 tonnes mostly as oxide (2.9 tU) at the Isfahan EUPP. This stock had increased by 460 kg since August. In addition, there was the 228 kg of near 20% enriched uranium in various forms. In December 2015, Iran shipped more than 11 tonnes of various low-enriched uranium materials to Russia, in accordance with the JCPOA. The shipment included all of Iran's nuclear material enriched to near 20% that was not already in the form of fabricated fuel plates for the Tehran Research Reactor.* The IAEA now must verify that Iran's enriched uranium stockpile is 300 kg or less at under 3.67% U-235. In exchange for the enriched uranium, Iran received an equivalent amount of natural uranium, 137 tonnes, most originating in Kazakhstan. * In May 2015 Iran had 228 kg U as 19.75% enriched uranium, 61.5 kg as oxide powder, 44.9 kg as TRR fuel, and 121.2 kg as scrap, waste, or in-process, and none as hexafluoride. The total of 228 kg U was the same in November, and 51.5 kg of this was in TRR fuel assemblies, plus a couple of kg in target irradiation plates. The remaining 175 kg would need to be exported under the JCPOA. This is half of what had been produced before some was downblended.
