Iran recently launched Advanced Nuclear Centrifuges at the Natanz Nuclear Plant to mark its National Nuclear Technology Day.
Iran has started enriching its uranium supply to 60 percent purity.
Iran has ever come to this level for the first time.
It is the closest level needed for a weapon.
Under the Joint comprehensive Plan of Action (JCPOA), also known as the 2015 Nuclear Agreement, Iran is restricted to use only certain number of Uranium enrichment centrifuges.
However, in May 2018, the US Government under Donald Trump abandoned the agreement and reimposed sanctions on Iran.
The current US Government under Joe Biden has pledged to return to JCPOA.
Centrifuge
It is used to separate particles suspended in a medium.
In a Nuclear Centrifuge, Uranium-235 is separated from Uranium-238.
The Nuclear Fuel used in nuclear reactor must have higher concentration of Uranium-235 isotope than that of its natural form, that is, Uranium-238.
The Uranium-235 is more radioactive than Uranium-238.
