Overall, there are six steps in the process. Starting with the extraction of uranium and ending with its being buried away, including the cyclic process of using U-235.
First of all, uranium is extracted from deep within the Earth. The ore gets processed and turned into pellets of fuel. Since uranium is radioactive, there are many safety measures in place to protect the workers. Uranium then undergoes a fission reaction in which other tiny particles collide with the fuel particles. This generates great heat, and this heat boils water, which produces steam. The steam produced turns the turbines, which, in order to make electricity, are connected to a generator.
Secondly, after about four years, the fuel has been depleted and removed from the nuclear reactor. Some of this fuel can be re-used if it gets re-processed. Even after this fuel has been used, it is still radioactive and dangerous; hence, the uranium is stored in a container lined with lead because radioactive particles cannot penetrate lead. This container is then buried in a safe place or stored in an underground vault.
