On Thursday , Iran resumed uranium enrichment at its Fordou nuclear plant in the north of the country by pumping uranium gas into its centrifuges, following a decision announced on Tuesday to further cut its commitments which were made in 2015 over its nuclear program.
"On Thursday ,uranium gas was pumped into centrifuge networks and the production and assembly of enriched uranium was started at Fordow facilities," located in about 180 kilometers south of Tehran, the Iranian Atomic Energy Organization said in a statement.
The whole process was conducted under the supervision of inspectors from the International Atomic Energy Agency of the United Nations.
Under the 2015 nuclear agreement, Tehran agreed to significantly reduce its nuclear activities in order to ensure its civilian nature exclusively in exchange for lifting part of the international sanctions that chocked its economy.
On Tuesday, Iranian President Hassan Rouhani announced the resumption of uranium enrichment activities that were frozen.
"The process will take a few hours to stabilize and by Saturday when IAEA inspectors visit the site again, uranium enrichment of 4.5 percent will have been completed," Nuclear Energy Organization spokesman Behrouz Kamalundi told a news briefing. Added "All of the centrifuges installed at Fordow are AR-1 , Uranium gas has been injected into four cascades of this type (696 centrifuges)."
He pointed out that "the remaining two series of centrifuges (348 centrifuges) will be used to produce and enrich stable isotopes in the facility."
Uranium enrichment activities, which were frozen under the nuclear agreement , resumed the day after a deadline set by other signatories (China, Russia, the United Kingdom, France and Germany) expired to help them overcome the consequences of the U.S. withdrawal from the agreement in May 2018.
This is the fourth step of the plan to reduce Iran's commitments which was launched in May, in response to the US withdrawal from the agreement and re-impose US sanctions on it ,by a decision of President Donald Trump
Through this policy, Tehran seeks to pressure other parties to help them bypass the sanctions that have caused a significant contraction of its economy.
