As of May 26, Iran had 125.2 metric tonnes of heavy water, an increase of 0.4 tonnes on February but still under the 130-tonne limit. As of 20 May, Iran had 174.1 kg (383 pounds) of enriched uranium, up from 163.8 kg in February but again within the relevant limit. Earlier this month Iran announced it was suspending some of its commitments under the 2015 Joint Comprehensive Plan of Action (JCPOA). As well as no longer respecting the limits on stocks, Iran has also said it will increase production of uranium and heavy water. The report also confirms Iran has not breached the uranium enrichment level of 3.67 percent specified in the JCPOA.
