The Canadian Space Mining Corporation (CSMC) has licensed the rights to develop a nuclear reactor for commercialization, according to an announcement made by CSMC earlier today. The reactor technology comes from the Canadian Nuclear Laboratories (CNL), and will be based on the Canadian-made SLOWPOKE research reactor.
This follows previous news that CSMC was working on development of a transportable nuclear fission reactor under the name โProject LEUNR,โ under the grant from the Canadian Space Agencyโs (CSA) Space Technology Development Program (STDP.).ย
Specifically, according to the announcement, CSMC and CNL โsigned a Memorandum of Understanding (MOU) and Licensing term sheetโฆto explore commercialization of the SLOWPOKE-2 reactor technology.โ This appears to be with an eye to turning the SLOWPOKE technology into the foundation of CSMCโs LEUNR reactor, which will now be developed with an eye to both space-based and terrestrial applications.
SLOWPOKE called โsafest reactor on the planetโย
The SLOWPOKE โ short for โSafe LOW-Power (K)Critical Experiment โ is a light water, self-regulating reactor that uses ceramic Uranium Dioxide fuel, beryllium reflectors,ย and passive cooling that can slow or stop the chain reaction if the water heats up or forms bubbles.ย The Royal Military College of Canada has a SLOWPOKE-2 reactor, used for research and to produce gamma and neutron radiation for research, analysis, and isotope production, and said that โit is the only type of nuclear reactor licensed in Canada for unattended operation in automatic mode.โย ย
(David Dunlop made the case for using the SLOWPOKE on Canadian submarines in the Canadian Naval Review in early 2020. Canadian submarines use electric propulsion, and Dunlop suggested using the SLOWPOKE reactors to charge them as part of a โhybrid designโ.)
CSMCโs announcement described SLOWPOKE as a reactor with โa proven track record of reliable, long-term operations,โ and heavily emphasized its safety record, saying โit is considered by some to be the safest reactor on the planet due to its numerous passive safety systemsโ. Eight of the reactors have been built, with three reactors still in operation.
CSMC said that there will be several key areas for collaboration between the two organizations. This will include โcollaborative research and development initiatives,โ and will also include development of the reactor into a โviable energy solutionโ for both powering lunar operations and providing energy for โapplications in remote locations including Canadaโs Arctic region.โ
Daniel Sax, CEO of CSMC, said that โthis is a pivotal moment in our journey to develop micro-reactors that meet current and future needs.โ
License at culmination of โyears of hard workโย

In correspondence with SpaceQ, Sax said that this was the result of โthree years of hard work;โ specifically that CSMC and CNL had been โworking on a plan for [the SLOWPOKE technology], both business and R&D wise, for the last several years.โ He said that this was โone of many milestones along the road.โย As CNL has been โa key technical partner of ours for the last few years,โ he added, working with their technology makes sense.ย
According to the CEO, โthe genesis of the idea came about from a first principles approach to filling key lunar gaps.โ As they worked on the question of mining in space, including on the Moon, it quickly became clear that โpower would be a gating factor, and solar wasnโt going to cut it for either thermal energy or [lunar] night survivability.โ Their Chief Scientist, Richard Boudreault, had been interested in the SLOWPOKE technology โdating back to his time on AECLโs boardโ (referring to Atomic Energy of Canada Ltd), and so CSMC decided that adapting SLOWPOKE would be โcore to the strategyโ for LENUR, as โstarting with an existing reactor and upgrading it makes sense.โย
A dual-use strategy also made sense to them as well. Sax said that he is โa big advocate of the use of a technology like LEUNR for space exploration,โ but he also recognizes that โthe needs in Canadaโs north are well known and well documented.โ He maintained that โif we’re going to hit the government’s net-zero goals, as well as replace diesel generators up there, we need solutions that work, and particularly ones that can get to market right away.โ He believes that LEUNR, using the SLOWPOKE reactorโs technology, will help achieve that, and โhelp tackle one of the biggest problems in Canada.โ
Sax emphasized that he sees this as a long term arrangement. โItโs an honor to work with the team [at CNL]โ, he said, โand [we] want to continue to do R&D with them, demonstrate the upgraded reactor with them, and ultimately build dozens of reactors with them as a partner.โ Sax wants to position CSMC as โa market leading reactor company,โ and sees the Canadian Nuclear Labs as a key governmental partner in achieving that goal. Part of that is a โbold plan to put the first reactor on the Moon,โ but another part will be helping with terrestrial power generation, and Sax said that โwe need to capitalize on these types of opportunities.โย
CNLโs Vice-President of Science & Technology, Dr. Stephen Bushby, said that CNL โis excited to work alongside AECL and CSMC to breathe new life into the SLOWPOKE nuclear reactor technology.โ He said that the agreement is โaligned with CNLโs efforts to commercialize this and other AECL reactor technologies.โย
Dr. Amy Gottschling, Vice- President of Science, Technology & Commercial Oversight at AECL, said that the collaboration โsignals another key step in cementing Canadaโs competitive position in the current and future nuclear marketโฆbuilding off the decades of work enabled by our national nuclear laboratories.โ
