URANIUM REFINING AND CONVERSION | Everything
2015-9-12 · Most nuclear reactors require uranium to be enriched from its natural isotopic composition of 0.7% U-235 (most of the rest being U-238) to 3.5 to 4% U-235. The uranium therefore needs to be in a gaseous form, and the most convenient way of achieving this is to convert the uranium oxides to uranium hexafluoride, commonly []

How is uranium made into nuclear fuel - World Nuclear ...
Uranium is the main fuel for nuclear reactors, and it can be found in many places around the world. In order to make the fuel, uranium is mined and goes through refining and enrichment before being loaded into a nuclear reactor. Nuclear fuel pellets, with each pellet – not much larger than a sugar cube – contains as much energy as a tonne ...
