According to a leaked IAEA report, as of May 13, Tehran's total stockpile of enriched uranium was estimated at 4,744.5 kg, while the limit in the 2015 deal was only 202.8 kg. The report also said Iran was continuing to enrich uranium to levels higher than the 3.67% limit set in the deal.

However, the report also noted that Iran had resolved two previous outstanding requests from the IAEA. Nuclear inspectors no longer had questions about traces of nuclear material found enriched to 83.7% at the Fordo underground facility. Inspectors also concluded their investigation of traces of nuclear material at the Marivan site near the city of Abadeh, about 525km southeast of Tehran, a facility believed to be linked to Iran’s secret nuclear program and where Tehran conducted high-intensity explosive tests in the early 2000s.

Also on May 31, the IAEA began reinstalling some of the monitoring equipment that had been initially deployed under the JCPOA. The additional equipment included surveillance cameras at a site in Isfahan where centrifuge components are made and monitoring equipment at two enrichment facilities that Iran had previously disclosed.
