Iran started enriching uranium at the Natanz nuclear plant with advanced IR-4 centrifuges, Reuters reports, citing the IAEA.
The report claims that on 15 March 2021, the Agency verified that Iran began feeding the cascade of 174 IR-4 centrifuges already installed at FEP with natural UF6.
Reuters reports that Iran has already increased the number of IR-2m machines, which are far more efficient than the IR-1, installed at the underground plant.
