Iran has started the process of enriching uranium to 60% fissile purity at an above-ground nuclear plant at Natanz, the U.N. nuclear watchdog said on Saturday, confirming earlier statements by Iranian officials, Reuters reported.
The move has complicated talks aimed at reviving Iran's nuclear deal with major powers as it is a big step towards producing weapons-grade uranium. read more
Iran had previously only reached 20% purity, and that was already a breach of the deal, which says Iran can only enrich to 3.67%. read more
Iran made the step up to 60% in response to an explosion that damaged equipment at the larger, underground Fuel Enrichment Plant at Natanz. Tehran has blamed Israel and named a man wanted in connection with the blast. read more
"The Agency today verified that Iran had begun the production of UF6 enriched up to 60%... at the (above-ground) Natanz Pilot Fuel Enrichment Plant," the International Atomic Energy Agency said in a statement.
UF6 is uranium hexafluoride, the form in which uranium is fed into centrifuges for enrichment.
A confidential IAEA report to member states seen by Reuters provided more details.
"According to Iran's declaration to the Agency, the enrichment level of the UF6 produced at PFEP was 55.3% U-235. The Agency took a sample of the produced UF6 for destructive analysis to independently verify the enrichment level declared by Iran. The results of this analysis will be reported by the Agency in due course," the report said.
