NASA could place a powerful 500-kilowatt-electric (kWe) nuclear reactor on the Moon by the end of 2030, as part of a bold, high-stakes move aimed at securing long-term US energy dominance in space.<\/p>\n

The system, developed under the space agency\u2019s Fission Surface Power Initiative, would represent a significant leap beyond the radioisotope generators that have powered missions like Voyager 1 and Voyager 2, and the Mars rovers for decades. <\/p>\n

According to NASA, in comparison to smaller systems, a 500-kWe reactor could continuously power lunar habitats, industrial equipment, communication arrays and even resource extraction operations. <\/p>\n

\u201cIt might sound like science fiction, but it\u2019s not,\u201d Sebastian Corbisiero, the Space Reactor Initiative national technical director, explained. \u201cIt is very realistic and can significantly boost what humans can do in space because fission reactors provide a step increase in the amount of available power.\u201d<\/p>\n

Powering the Moon<\/p>\n

Although no fission reactors are currently operating in space, the agency issued a directive on fission surface power. It reportedly intends to place a reactor on the Moon by fiscal year 2030. The strategy is outlined in a new report funded by the Idaho National Laboratory (INL). <\/p>\n

Titled \u201cWeighing the Future: Strategic Options for US Space Nuclear Leadership,\u201d the document outlines three approaches. The most ambitious, described as \u201cGo Big or Go Home,\u201d calls for a 100\u2013500 kWe reactor program<\/a> led by NASA or the Department of War, with support from the Department of Energy. <\/p>\n

The report argues that scaling up to 100-500 kilowatt-electric (kWe) systems is essential if the nation aims to stay ahead in space nuclear power<\/a>. Meanwhile, a second option, named \u201cChessmaster\u2019s Gambit,\u201d proposes two smaller sub-100 kWe systems developed through public-private partnerships. <\/p>\n

One project, led by NASA, would reportedly build a reactor for lunar orbit or the Moon\u2019s surface. The other, led by the Department of Defense, would develop an in-space system.<\/p>\n

Ultimately, a third, more cautious alternatives involves developing a\u00a0small, under one kWe, radioisotope power system<\/a>, in order to establish regulatory frameworks and technical groundwork before scaling.<\/p>\n

Space\u2019s nuclear future<\/p>\n

Unlike terrestrial advanced reactors, space-bound fission systems<\/a> must operate under entirely different conditions. \u201cThe big differences are mass, temperature and component endurance,\u201d Corbisiero emphasized.<\/p>\n

At the same time, everything sent into space has to launch on a rocket, so the reactor must be as light as possible while still strong and durable. According to Corbisiero, that makes weight a top priority. <\/p>\n

What\u2019s more, water, commonly used in Earth-based reactors<\/a>, may not be practical due to the heavy pressure vessels required. NASA is evaluating high-temperature alternative cooling systems to reduce mass while maximizing power density.<\/p>\n

The reactors must also endure extreme temperature swings, radiation exposure, and micrometeoroid risks, all without routine servicing. INL is expected to serve as the technical hub for reactor testing and fuel qualification.<\/p>\n

With specialized staff and state-of-the-art facilities like the Transient Reactor Test Facility, INL is equipped to conduct critical testing of nuclear propulsion reactor fuels and host new reactor technologies on-site.<\/p>\n

\u201cWe\u2019re potentially on the cusp of a major step forward regarding nuclear power for space applications,\u201d Corbisiero concluded in a press release<\/a>. \u201cTo be a part of an effort like this \u2013 that is as exciting as it gets. That\u2019s something you tell your grandkids.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"NASA could place a powerful 500-kilowatt-electric (kWe) nuclear reactor on the Moon by the end of 2030, as…\n","protected":false},"author":2,"featured_media":279700,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[600,13656,20718,85647,3323,111,139,57275,69,393,10112,147,392,3694,3337],"class_list":{"0":"post-279699","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-energy-amp-environment","9":"tag-extraterrestrial","10":"tag-mars-mission","11":"tag-moon-base","12":"tag-nasa","13":"tag-new-zealand","14":"tag-newzealand","15":"tag-nuclear-reactor","16":"tag-nz","17":"tag-physics","18":"tag-power","19":"tag-science","20":"tag-space","21":"tag-sustainability","22":"tag-usa"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/279699","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=279699"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/279699\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/279700"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=279699"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=279699"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=279699"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
