() Uranium ore can be mined by underground or open-cut methods, depending on its depth. Then it is treated with acid to dissolve the uranium, which is recovered from solution.Uranium may also be mined by in situ leaching (ISL), where it is dissolved from a porous underground ore body in situ and pumped to the surface.It is therefore said to be 'fissile' and we use the expression 'nuclear fission'.Meanwhile, like all radioactive isotopes, they decay.
A typical 1000 megawatt (MWe) reactor can provide enough electricity for a modern city of up to one million people.
The heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.
The chain reaction that takes place in the core of a nuclear reactor is controlled by rods which absorb neutrons and which can be inserted or withdrawn to set the reactor at the required power level.
The end product of the mining and milling stages, or of ISL, is uranium oxide concentrate (U). Before it can be used in a reactor for electricity generation, however, it must undergo a series of processes to produce a useable fuel.
For most of the world's reactors, the next step in making the fuel is to convert the uranium oxide into a gas, uranium hexafluoride (UF), which enables it to be enriched.
