The element commonly associated with nuclear energy is uranium. Uranium is a heavy metal that undergoes nuclear fission, a process in which its nuclei split into smaller nuclei, releasing a significant amount of energy. This mechanism is harnessed in nuclear power plants to generate electricity. Uranium-235 is the isotope most commonly used in nuclear reactors due to its ability to sustain a chain reaction. Despite its potential for low-carbon energy production, nuclear energy also raises concerns regarding safety, radioactive waste disposal, and the potential for nuclear proliferation. Thus, its use is a topic of ongoing debate.
