Carbon dioxide
Step-by-step explanation:
Nuclear power plants are a type of power plant that use the process of nuclear fission in order to generate electricity and do this by using nuclear reactors, where the heat generated by the reactor converts water into steam, which spins a turbine and a generator
They get their thermal power from splitting the nuclei of atoms in their reactor core, with uranium being the dominant choice of fuel in the world today
As a fuel nuclear power plants use uranium and mining of uranium release carbon dioxide in high amount into the environment
