Rouhani Government Authorizes Return to 20% Uranium Enrichment Posted by Scott Lucas | Dec 29, 2020 | In its most significant suspension of commitments under the 2015 nuclear deal, Iran’s Rouhani Government has authorized a return to the enrichment of 20% uranium. Before the agreement in July 2015 with the 5+1 Powers (US, UK, Germany, China, Russia, and France), Iran had produced the 20% uranium, which can potentially be further enriched to a military grade of more than 90%. Responding to the Trump Administration’s withdrawal from the agreement and its comprehensive sanctions, the Government had broken the deal’s limit on stocks of 3.67% uranium, raised enrichment to 4.5%, and installed advanced uranium centrifuges. But it had refrained from the crossing of the 20% line.
