====Generation IV reactors====
[[Generation IV reactor]]s are a set of theoretical nuclear reactor designs. These are generally not expected to be available for commercial use before 2040–2050,<ref name="sa-2014">{{Cite web |last=De Clercq |first=Geert |date=October 13, 2014 |title=Can Sodium Save Nuclear Power? |url=https://www.scientificamerican.com/article/can-sodium-save-nuclear-power/ |access-date=2022-08-10 |website=Scientific American |language=en |archive-date=29 July 2021 |archive-url=https://web.archive.org/web/20210729090905/https://www.scientificamerican.com/article/can-sodium-save-nuclear-power/ |url-status=live }}</ref> although the World Nuclear Association suggested that some might enter commercial operation before 2030.<ref name="gen-iv_wna-2020">[https://world-nuclear.org/information-library/nuclear-fuel-cycle/nuclear-power-reactors/generation-iv-nuclear-reactors.aspx ''Generation IV Nuclear Reactors''] {{Webarchive|url=https://web.archive.org/web/20230330074852/https://www.world-nuclear.org/information-library/nuclear-fuel-cycle/nuclear-power-reactors/generation-iv-nuclear-reactors.aspx |date=30 March 2023 }}. World Nuclear Association, update Dec 2020</ref> Current reactors in operation around the world are generally considered second- or third-generation systems, with the first-generation systems having been retired some time ago. Research into these reactor types was officially started by the Generation&nbsp;IV International Forum (GIF) based on eight technology goals. The primary goals being to improve nuclear safety, improve proliferation resistance, minimize waste and natural resource utilization, and to decrease the cost to build and run such plants.<ref name="UIC1">{{cite web |title=Generation IV Nuclear Reactors |publisher=[[World Nuclear Association]] |url=http://world-nuclear.org/info/inf77.html |access-date=29 January 2010 |archive-date=23 January 2010 |archive-url=https://web.archive.org/web/20100123063413/http://www.world-nuclear.org/info/inf77.html |url-status=dead }}</ref>
