Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provided about 5.7% of the world's energy and 13% of the world's electricity, in 2012. In 2013, the IAEA report that there are 437 operational nuclear power reactors (although not all are producing electricity), in 31 countries. More than 150 naval vessels using nuclear propulsion have been constructed.
There is an ongoing debate about the use of nuclear energy. Proponents, such as the World Nuclear Association, the IAEA andEnvironmentalists for Nuclear Energy contend that nuclear power is a sustainable energy source that reduces carbon emissions.Opponents, such as Greenpeace International and NIRS, believe that nuclear power poses many threats to people and the environment.
Nuclear power plant accidents include the Chernobyl disaster (1986), Fukushima Daiichi nuclear disaster (2011),
