Nuclear energy, also known as atomic energy, is produced by physical reactions involving the nucleus of an atom. An atom is the smallest unit of matter, and the nucleus is its dense central core. Nuclear reactions such as fission (splitting nuclei), fusion (combining atoms), and radioactive decay convert relatively small amounts of matter into large quantities of energy. Nuclear energy can be harnessed for generating electricity, powering vehicles like submarines and space probes, pursuing scientific and medical research, or creating weapons with tremendous destructive force.
Nuclear energy accounts for more than 11 percent of the electricity generated worldwide as of 2017. According to the International Atomic Energy Agency (IAEA) there were 447 nuclear power reactors operating in 30 countries that...Read more
