Nuclear power in France is a type of energy that is created in power plants called nuclear power plants. These plants use a process called nuclear fission, which is when atoms of certain elements are split apart, causing them to release a lot of energy. This energy is used to generate electricity, which is used to power our homes and other things. France is one of the countries that produces the most electricity from nuclear sources. This is because they have a lot of nuclear power plants, which are very efficient, so they are able to make a lot of energy. France is also very careful about how they store and deal with the waste created by nuclear power plants, which helps them create energy safely.
