At number 4 is Japan , with a total of 33 operational nuclear plants that have 31.7GW net installed capacity . Two reactors , Ohma 1 and Shimane 3 , are currently under construction but will , when finished , account for an additional net capacity of 2.6GW

Prior to the Fukushima nuclear incident in 2011 , 30 % of Japan ’ s energy requirements were derived from nuclear energy . Now , the country imports 90 % of its energy requirements .

Nuclear Generation : 50.8GW

A net installed capacity of 50.8GW via 51 nuclear reactors makes China the third biggest nuclear energy-producing country in the world .

Though currently under construction , China is planning to grow its power system , with 18 reactors to open soon . Collectively , this would generate 17.2GW for China ’ s power systems .
