DUBAI, United Arab Emirates — Iran will begin enriching uranium with thousands of advanced centrifuges at its two main nuclear facilities at Fordo and Natanz, the United Nations' nuclear watchdog said Friday, further raising tensions over Tehran's program as it enriches at near weapons-grade levels.
The notice from the International Atomic Energy Agency only mentioned Iran enriching uranium with new centrifuges to 5% purity, far lower than the 60% it currently does — likely signaling that it still wants to negotiate with the West and the incoming administration of President-elect Donald Trump.
However, it remains unclear how Trump will approach Iran once he enters office, particularly as it continues to threaten to attack Israel amid its war on Hamas in the Gaza Strip and just after a ceasefire started in its campaign in Lebanon. Trump withdrew America from Iran's nuclear deal with world powers in 2018, setting in motion a series of attacks and incidents across the wider Mideast.
Iran's mission to the United Nations did not respond to a request for comment over the IAEA's report. Tehran had threatened to rapidly advance its program after the Board of Governors at the IAEA condemned Iran at a meeting in November for failing to cooperate fully with the agency.
In a statement, the IAEA outlined the plans Iran informed it of, which include feeding uranium into some 45 cascades of its advanced IR-2M, IR-4 and IR-6 centrifuges.
Cascades are a group of centrifuges that spin uranium gas together to more quickly enrich the uranium. Each of these advanced classes of centrifuges enrich uranium faster than Iran's baseline IR-1 centrifuges, which have been the workhorse of the country's atomic program. The IAEA did not elaborate on how many machines would be in each cascade but Iran has put around 160 centrifuges into a single cascade in the past.
It's unclear if Iran has begun feeding the uranium yet into the centrifuges. Tehran so far has been vague about its plans. But starting the enrichment at 5% gives Tehran both leverage at negotiations with the West and another way to dial up the pressure if they don't like what they hear. Weapons-grade levels of enrichment are around 90%.
Since the collapse of Iran's 2015 nuclear deal with world powers following the U.S.' unilateral withdrawal from the accord in 2018, it has pursued nuclear enrichment just below weapons-grade levels. U.S. intelligence agencies and others assess that Iran has yet to begin a weapons program.
