Note "The SLOWPOKE-2 uses 93% (originally) enriched uranium in the form of 28% uranium-aluminum alloy with aluminum cladding." More modern designs would have to use lower enrichment to comply with current anti-proliferation matter.
And " The Chalk River prototype went critical in 1970, and was moved to the University of Toronto in 1971. It had one sample site in the beryllium reflector and operated at a power level of 5 kW. In 1973 the power was increased to 20 kW "
See also - "AECL also designed and built a scaled-up version (2-10 MWth) called SLOWPOKE-3 for district heating at its Whiteshell Nuclear Research Establishment in Manitoba." That's not for electrical generation.
And finally - "SLOWPOKE reactors are used mainly for neutron activation analysis (NAA), in research and as a commercial service, but also for teaching, training, irradiation studies, neutron radiography (at the Royal Military College of Canada) and the production of radioactive tracers."
