What is highly enriched uranium?
The level of enrichment in uranium refers to the concentration of U-235, its most fissile isotope. The higher the concentration the easier it is to trigger a chain reaction. Highly enriched uranium (HEU) refers to anything above 20%. Read More »

What is Enriched Uranium?
Enriched uranium is the action that is carried out on uranium, in which the ratio of the abundance of the isotope uranium 235 to that of the isotope uranium 238 is increased above that found in natural uranium. Read More »

Fissionable uranium needs to have a significant ratio of U-235 vs U-238. This is because U-235 is less stable and will react more easily. In other words, more U-235 means a fast reaction, meaning more energy is liberated.

Uranium contains to isotopes U235 in small quantity and U238 in larger quantity. the ist isotope is used to produce plutonium and hence atomic bomb, the separation of U235 from mixture in maximum purity this is known as uranium enrichment.
