Nuclear energy is a type of energy that is made by splitting atoms. In a nuclear power plant, atoms are split apart in a process called nuclear fission. This process releases a lot of energy in the form of heat. A World Nuclear Industry Status Report is a document that tells people about how the use of nuclear energy is changing around the world. It looks at the number of nuclear power plants in operation and what new kinds of nuclear technologies are being developed. The report also includes statistics about how much electricity is being generated from nuclear power, how much CO2 is being released, and other important information. The report helps us understand how nuclear energy is being used around the world and how it affects the environment.
