The primary output of nuclear power plants is electricity. These facilities generate power through the process of nuclear fission, where atomic nuclei are split to release a substantial amount of energy. In a nuclear reactor, the heat produced from fission converts water into steam, which then drives turbines connected to generators. Although nuclear energy is a low-carbon electricity source, it does produce radioactive waste that requires careful management and disposal. Nuclear power is a significant part of the energy mix in various countries, helping to reduce reliance on fossil fuels and combat climate change.
