Nuclear power plants obtain heat from nuclear fission of uranium.
The heat is transferred to steam which then operates a steam turbine to generate electricity.
Nuclear power plants can provide a large amount of electricity without emitting carbon during their operation.
In addition, nuclear fuel can be reused after reprocessing.
For these reasons, nuclear energy is today an important source of energy.
However, the use of radiactive materials requires special precautions as radiation can cause serious effects on humans and the environment.
The storage of radioactive waste remains a major issue.
