Iranian nuclear officials are claiming that the country is quadrupling its production of enriched uranium.

The state-run IRNA news agency in Iran is claiming that Iran is increasing its uranium production and that the International Atomic Energy Agency had been alerted to this development. The Independent cited Iranian officials who insisted that the uranium would only be enriched to 3.67 percent purity. In order to be used in an atomic bomb, uranium purity needs to be at 90 percent.

At this increased rate of production, it won’t be long before Iran has a larger stockpile of enriched uranium than is permitted under the 2015 nuclear deal brokered by the Obama administration. While the United States pulled out of this deal in 2018, other signatories have tried to keep it going.
