Nuclear safety covers the actions taken to prevent [[nuclear and radiation accidents and incidents]] or to limit their consequences. The nuclear power industry has improved the safety and performance of reactors, and has proposed new, safer (but generally untested) reactor designs but there is no guarantee that the reactors will be designed, built and operated correctly.<ref name=globen/> Mistakes do occur and the designers of reactors at [[Timeline of the Fukushima nuclear accidents|Fukushima]] in Japan did not anticipate that a tsunami generated by an earthquake would disable the backup systems that were supposed to stabilize the reactor after the earthquake,<ref>{{cite web  |url=http://www.thebulletin.org/web-edition/columnists/hugh-gusterson/the-lessons-of-fukushima  |title=The lessons of Fukushima  |author=Gusterson, Hugh  |date=16 March 2011  |work=Bulletin of the Atomic Scientists  |url-status=dead  |archive-url=https://web.archive.org/web/20130606023005/http://www.thebulletin.org/web-edition/columnists/hugh-gusterson/the-lessons-of-fukushima  |archive-date=6 June 2013    }}</ref> despite multiple warnings by the NRG and the Japanese nuclear safety administration.{{citation needed|date=April 2016}} According to [[UBS]] AG, the [[Fukushima I nuclear accidents]] have cast doubt on whether even an advanced economy like Japan can master nuclear safety.<ref>{{cite web|url=http://www.businessweek.com/news/2011-04-04/fukushima-crisis-worse-for-atomic-power-than-chernobyl-ubs-says.html |title=Fukushima Crisis Worse for Atomic Power Than Chernobyl, UBS Says |author=Paton, James |date=4 April 2011 |work=Bloomberg Businessweek |url-status=dead |archive-url=https://web.archive.org/web/20110515064305/http://www.businessweek.com/news/2011-04-04/fukushima-crisis-worse-for-atomic-power-than-chernobyl-ubs-says.html |archive-date=15 May 2011 }}</ref> Catastrophic scenarios involving terrorist attacks are also conceivable.<ref name=globen>{{cite web |url=http://www.stanford.edu/group/efmh/jacobson/Articles/I/WWSEnergyPolicyPtI.pdf |title=Providing all Global Energy with Wind, Water, and Solar Power, Part I: Technologies, Energy Resources, Quantities and Areas of Infrastructure, and Materials |author1=Jacobson, Mark Z.  |author2=Delucchi, Mark A.  |name-list-style=amp |year=2010 |work=Energy Policy |page=6 }}{{dead link|date=December 2015}}</ref> An interdisciplinary team from [[MIT]] has estimated that given the expected growth of nuclear power from 2005 to 2055, at least four serious nuclear accidents would be expected in that period.<ref>{{cite web |url=http://web.mit.edu/nuclearpower/pdf/nuclearpower-full.pdf |title=The Future of Nuclear Power |author=Massachusetts Institute of Technology |year=2003 |page=48 |access-date=15 June 2011 |archive-date=12 April 2019 |archive-url=https://web.archive.org/web/20190412094517/http://web.mit.edu/nuclearpower/pdf/nuclearpower-full.pdf |url-status=live }}</ref>
