Nuclear power plant (nuclearpowerplant) is the use of nuclear fission (NuclearFission) reaction of the energy released by the power plant to generate electricity. The current commercial operation of nuclear power plants are the use of nuclear fission reaction and power generation. Nuclear power plants are generally divided into two parts: the use of atomic fission to produce steam nuclear island (including reactor units and a circuit system) and the use of steam to generate electricity on the conventional island (including turbine generator system), the use of fuel is generally radioactive heavy metals: uranium, plutonium.
