Iran plans to install hundreds more advanced uranium-enriching centrifuges at an underground plant in breach of its deal with major powers, a U.N. nuclear watchdog report showed on Friday, a move that will raise pressure on U.S. President-elect Joe Biden.
The confidential International Atomic Energy Agency report obtained by Reuters said Iran plans to install three more cascades, or clusters, of advanced IR-2m centrifuges in the underground plant at Natanz, which was apparently built to withstand aerial bombardment.
Iran’s nuclear deal with major powers says Tehran can only use first-generation IR-1 centrifuges, which are less efficient, at the underground plant and that those are the only machines with which Iran may accumulate enriched uranium.
Iran recently moved one cascade of 174 IR-2m machines underground at Natanz and is enriching with it. It already planned to install two more cascades of other advanced models there, in addition to the 5,060 IR-1 machines that have been enriching for years in the plant built for more than 50,000.
“In a letter dated 2 December 2020, Iran informed the Agency that the operator of the Fuel Enrichment Plant (FEP) at Natanz ‘intends to start installation of three cascades of IR-2m centrifuge machines’ at FEP,” the IAEA’s report to its member states said.
