The UN nuclear agency has confirmed that Iran plans to install around 6,000 new centrifuges to enrich uranium, according to a report seen by AFP on Friday.
“Iran informed the Agency that it intended to feed” around 6,000 centrifuges at its sites in Fordo and Natanz to enrich uranium to up to five percent, higher than the 3.67 percent limit Tehran had agreed to in 2015.
The Iranian decision came in response to a resolution adopted on November 21 by the UN nuclear watchdog that censures Tehran for what the agency called lack of cooperation.
On Thursday, Iran had threatened to end its ban on acquiring nuclear weapons if Western sanctions are reimposed.
The country’s foreign minister, Abbas Araghchi, said in an interview that the nuclear debate inside Iran is likely to shift towards the possession of its own weapons if the west goes ahead with a threat to reimpose all UN sanctions,
What are centrifuges?
They are precise devices with cylinders that rotate much faster than the speed of sound, to collect enriched uranium atoms.
To explain how centrifugation works, rotating cylinders are much like medical laboratory equipment used to test blood.
The high rotation speeds exert a rotational force that separates the various components of blood as a function of their density and quantity in the sample.
In the case of uranium, the centrifuge operates using the familiar principle of centrifugal force. This force separates two gases of unequal masses in a spinning cylinder or tube. The heavier uranium-238 isotope collects at the outer edges of the cylinder while the lighter uranium-235 collects near the axis of rotation at the center.
Around 20 kg of uranium enriched to a 90% purity level would be needed for a single nuclear weapon. It would take about 1,500 SWU to produce a weapon-equivalent of 90 percent-enriched uranium from this enriched uranium.
At Fordo, Iran is currently using the two only operating cascades of IR-6 centrifuges there to enrich to 60% from 20%.
There are 1,044 centrifuges active at the Fordo uranium enrichment plant, Iran's President Masoud Pezeshkian said.
He had earlier asked the Iran Atomic Energy Agency to begin inserting uranium gas into newly activated advanced centrifuges.
Early this month, a spokesperson for the US State Department said Iran's expansion of uranium enrichment activities in defiance of key nuclear commitments is "a big step in the wrong direction”.
His statement came after Tehran announced it would start injecting uranium gas into centrifuges at Fordo.
Dispute
The Nuclear Non-Proliferation Treaty, signed in 2015 between Tehran and Western countries, says advanced centrifuges for uranium enrichment could operate until January 2027.
The difference between the first generation of centrifuges (IR-1) and the other generations is speed. The latest generation, IR-6, could enrich uranium up to 10 times faster than the first-generation IR-1, according to Iranian officials.
During the heyday of its nuclear program, Iran operated a total of 10,204 first-generation IR-1 centrifuges at the Natanz and Fordo facilities. But under the deal, Iran's commitments included operating no more than 5,060 IR-1 centrifuges for a period of 10 years.
Although the centrifuges that Iran installed before the 2015 nuclear deal were of the first generation, Tehran’s recent uranium enrichment activity at nuclear sites has reached disturbingly advanced levels, potentially increasing the nuclear proliferation risk.
Major centrifuge activities in Iran
May 2008: Iran installed several centrifuges including more modern models.
March 2012: Iranian media announced 3,000 centrifuges at Natanz.
August 2012: The International Atomic Energy Agency announced that Iran had installed large parts of the centrifuges at Fordo.

February 2013: IAEA says Iran has operated 12,699 IR-1 centrifuges at the Natanz site.
June 2018: Iran’s supreme leader revealed Tuesday that it ultimately wants 190,000 nuclear centrifuges — a figure 30 times higher than world powers allowed under the 2015 deal.
September 2019: Iran mounted 22 IR-4, one IR-5, 30 IR-6, and three IR-6 for testing, outside the treaty boundaries.
