Climate change will affect all reaches of the globe. The most susceptible regions must adapt first by employing new sustainable technologies and strategies. Canada’s North is particularly susceptible to effects of climate change, which will cause a 0.2–1.2°C increase per decade. Temperature anomalies, which have been detected globally since 1880 are magnified at upper latitudes, which includes the Canadian Arctic. Canada has nearly 300 remote communities and resource-based businesses (usually mines) that rely on locally produced heating and electricity. Reliable power for remote communities is critical for sustainable life in the Canadian Arctic. Power demand for communities and commercial operation ranges from a few hundred kilowatt-hours to tens of megawatt-hours. Currently many communities and commercial operations rely on fossil fuel generation to electricity and hot water demands. The vast majority of these systems have reached their design life or will within the next decade. What will be the method of choice for the next generation of power generation? Should we continue to burn fossil fuels or consider other options? This extended abstract examines energy geotechnics questions of using small modular reactors to meet the current and future power demand for the range of remote Canadian communities in the arctic.
