Conventional thermal power plants use various boilers to burn coal, oil or gas as fuel, and burn water to heat it into steam at high temperature and high pressure to drive steam turbine generators to produce electricity.
The “boiler” of a nuclear power plant (power station) is called a “nuclear reactor”. Its fuel is not a fuel that uses chemical energy like coal, oil or gas, but uses "nuclear fuel". " like uranium, which uses atomic nuclei. The fission energy released by fission is called "nuclear energy."
Conventional thermal power plants use the reorganization of the molecular bonding system to release chemical energy, which is relatively easy to reorganize and energy changes are small while nuclear power plants reorganize the nuclear system;protons and neutrons (for the nuclear force), which is more difficult, but the energy changes a lot. If the energy release rate is quickly released without restriction, conventional chemical fuels can make conventional explosives (bombs), while nuclear fuel bombs are atomic bombs (uranium nuclear fuel) or hydrogen bombs (hydrogen isotopes).
