Nuclear energy is the energy released from the nucleus of an atom through processes like nuclear fission or fusion. It is a powerful and efficient source of electricity generation.
Nuclear fission: The splitting of an atomic nucleus into two smaller nuclei, releasing a large amount of energy.
Nuclear fusion: The combining of two atomic nuclei to form a larger nucleus, also releasing a significant amount of energy.
Radioactive waste: The hazardous byproduct produced during nuclear reactions that requires careful disposal to prevent harm to humans and the environment.
