Answer:
A nuclear reactor converts into electricity the heat produced by the fission of uranium nuclei. This electricity production can be adjusted according to demand. During normal operation, nuclear reactors are quite environmentally friendly, particularly with regard to greenhouse gases. Since the 1950s, reactors have evolved into “generations”, learning from the rare accidents to enhance their safety and robustness. Radioactive waste is produced in limited volumes, which allows for its containment in the very long term, but its management remains controversial.
