{{Further|Nuclear power|Nuclear reactor technology}}
Nuclear power is a type of nuclear technology involving the controlled use of nuclear fission to release energy for work including propulsion, heat, and the generation of electricity. Nuclear energy is produced by a controlled nuclear chain reaction which creates heat—and which is used to boil water, produce steam, and drive a steam turbine. The turbine is used to generate electricity and/or to do mechanical work.

Currently nuclear power provides approximately 15.7% of the world's electricity (in 2004) and is used to propel [[aircraft carrier]]s, [[icebreaker]]s and [[submarine]]s (so far economics and fears in some ports have prevented the use of nuclear power in transport ships).<ref>{{cite web|url=http://world-nuclear.org/info/inf34.html|title=Nuclear-Powered Ships - Nuclear Submarines - World Nuclear Association|website=world-nuclear.org|access-date=9 May 2018|url-status=live|archive-url=https://web.archive.org/web/20130214062612/http://www.world-nuclear.org/info/inf34.html|archive-date=14 February 2013}}</ref> All [[nuclear power plant]]s use fission. No man-made fusion reaction has resulted in a viable source of electricity.
