The illustration above demonstrates how nuclear power is generated by uranium. This process consists of six main steps.
First, uranium is mined from the earth by machines. Next, the retrieved ore is processed and enriched to make U-235 fuel pellets in order to be suitable and safe for powering. After that, these pellets are fed into nuclear power generators to make electricity for different uses.
After four year’s time, the fuel becomes spent and is removed. Then, some spent fuel may be re-processed and then re-used, so they are fed into the power plants again. This cycle goes on until the pellets can no longer be re-processed to produce electricity. At this stage, they are stored in specific containers and buried underground so that the radiation from the pellets will not contaminate the environment.
To conclude, the above figure shows the procedures to generate nuclear power from crude uranium from earth, and how used fuels may be recycled to drive power again.
