In nuclear power plants, energy is produced by? Answer: Heat released during nuclear fusion

In nuclear power plants, energy is produced through nuclear fission, where the nucleus of a heavy atom (like Uranium-235 or Plutonium-239) splits into smaller nuclei, releasing a large amount of heat energy. This heat is then used to produce steam, which drives turbines to generate electricity.
