Nuclear energy has large unit energy and abundant resources, and is the only economic, safe and clean energy that can replace conventional energy on a large scale. At present, there are 62 nuclear power units in China, of which 47 units have been loaded and put into operation, with a total installed capacity of 44645.16 MWe, distributed in 18 nuclear power plants.
