Uranium is a naturally occurring radioactive material found in rocks, soil, and water, which, when enriched, is used as a source of fuel for nuclear reactors.
It comes in the form of three natural isotopes (chemical elements that contain equal numbers of protons but different numbers of neutrons in their nuclei): uranium-234 (U-234), uranium-235 (U-235) and uranium-238 (U-238). U-235 is highly radioactive; the other isotopes are not.
According to the United Nations’ International Atomic Energy Agency (IAEA), uranium enrichment is “the process through which the isotopic proportion of U-235 is increased from 0.72 percent to up to 94 percent”.
The IAEA says uranium is considered low-enriched if its isotopic proportion of U-235 remains below 20 percent. This is generally used in civilian, commercial reactors to generate power for homes and industries. It is considered highly enriched if its isotopic proportion is beyond 20 percent.
Enrichment needs to cross 90 percent for it to be considered weapons-grade.
Uranium also needs to be in the form of a gas to carry out the enrichment process, and most countries, including Iran, use the process of spinning uranium hexafluoride in order to enrich it. This involves feeding the gas into fast-spinning centrifuges. The lighter U-235 separates from the heavier U-238.
The useful enriched uranium-235 is then captured for nuclear fuel.
MV Ramana, professor in Disarmament, Global and Human Security at the University of British Columbia, told Al Jazeera that the current discussion about how long Iran should suspend enriching uranium is primarily a process of bargaining.
“Both the US and Iranian governments have staked a lot of political capital on Iran’s enrichment programme. The dispute in recent years and months has been that Trump wanted Iran to completely abandon the programme, and Iran refusing to ever do that,” he said.
Chris Featherstone, a political scientist at the University of York, said that for Trump, it’s all about being able to justify his claims that he is winning the war.

Why are the US, Iran arguing over duration of uranium enrichment ban?
The US reportedly wants Iran to stop enriching for 20 years. Iran has agreed to five years. Here's why that matters.
