Iran’s accelerating uranium enrichment has intensified global alarm, especially after U.S. strikes on Natanz, Isfahan, and Fordow—sites central to Tehran’s nuclear capabilities. While Iran insists its programme is peaceful, the IAEA’s finding of 60% enrichment pushes it dangerously close to weapons-grade levels. Understanding how scarce U-235 enables fission is key: peaceful reactors need just 3–5%, but weapons demand over 90%. As Iran nears that threshold, fears of a destabilising Middle-East power shift grow rapidly.

00:00For years now, there has been speculation among diplomatic and defence circles that
00:22Iran is secretly building a nuclear bomb.
00:26This speculation surfaced once again when the US struck Iran's nuclear facilities
00:31in June, including Natanz, Isfahan and Fodo.
00:37Natanz and Fodo are Iran's uranium enrichment sites, and Isfahan is the site that provides
00:43the raw materials.
00:45Now, even though Iran has repeatedly claimed that all its nuclear programmes are peaceful
00:51in nature, even the International Atomic Energy Agency, the IAEA, has refused to guarantee
00:58the same.
01:00Here it becomes important to understand what uranium enrichment actually is, and how it
01:05can ultimately be used to create a nuclear weapon.
01:09First, we need to understand what it means to enrich uranium.
01:14And to understand that, we need to know about uranium isotopes and about how an atom splits
01:19in a nuclear fission reaction.
01:22We all know that atoms are made up of protons, neutrons and electrons.
01:28Uranium has a fixed number of protons, 92.
01:31But there are different varieties of uranium, all with 92 protons but different numbers of
01:36neutrons.
01:38These different versions of the same atom are what we call isotopes.
01:43Now there are broadly two main isotopes of uranium.
01:46One is uranium-238, which has 92 protons and 146 neutrons.
01:53And the other is uranium-235, with 92 protons and 143 neutrons.
01:59Of these two isotopes, uranium-238 makes up 99.27% of all naturally occurring uranium, while
02:08uranium-235 is just 0.072%.
02:14And this is where the main challenge lies when using uranium for a nuclear program.
02:19Nuclear power reactors and nuclear weapons work only on the uranium-235 isotope because
02:27it's the only one that can sustain a chain-fission reaction, the process that produces energy.
02:33This is where enrichment comes in.
02:36Uranium enrichment basically means taking naturally found uranium and increasing the proportion
02:42of uranium-235 by removing uranium-238.
02:46For what we call a peaceful nuclear reaction, just 3-5% uranium-235 is enough to sustain a chain
02:53reaction and produce electricity.
02:56But to make a nuclear weapon, uranium-235 needs to be enriched to at least 20%.
03:03This is called highly enriched uranium.
03:07Coming back to Iran's nuclear program, the IEEA says Iran has already enriched large quantities
03:13of uranium to 60%.
03:15And from this point, Tehran can relatively easily go up to 90% enriched uranium, what
03:21we call weapons-grade uranium.
03:23This is why Iran is considered at extreme risk of producing nuclear weapons, keeping the entire
03:29Middle East, especially Israel and Saudi Arabia, and even the United States, in a constant state
03:35of tension, fearing that Iran may soon emerge as a nuclear weapons state.
