According to an IAEA report, Iran has begun enriching uranium at its underground plant in Natanz with a cascade of advanced IR-4 centrifuges.
“The agency confirmed on March 15, 2021, that Iran has started feeding natural UF6 (uranium hexafluoride) to the cascade of 174 IR-4 centrifuges installed at the fuel enrichment plant,”Reuters quotes excerpts from the IAEA report.
Iran plans to install a second cascade of IR-4 centrifuges in Natanz, the agency has learned. It is noted that the installation of this cascade has not yet begun.
In May 2018, the United States withdrew from the agreement and reinstated tough sanctions against the Islamic Republic. Iran, in turn, announced a gradual reduction of its obligations, while the European participants considered it necessary to preserve the agreement.
On January 5, this year, in the context of strained relations with Washington, Tehran announced the rejection of the “last key restriction in the nuclear deal” concerning the number of centrifuges for enriching uranium.
It has been reported that Iran has achieved 20% uranium enrichment at the Fordow facility, which is enough to carry out some nuclear weapons work.
