A number of arctic communities in Canada remain disconnected from national power grids and road networks. Today they produce their elelectricity using diesel generators, for which the fuel can be shipped only during a few summer months. The resulting cost of electricity is about ten times higher than for on-grid communities. Solar power is obviously not an option during the polar winter.
In addition, mining sites in the Canadian arctic have huge expenditures for transporting fuel by ice-road to their premises. Therefore, a significant fraction of the cost for the commodities produced by mining is related to fuel.
The use of small nuclear reactors for power production in off-grid communities and mining sites could address the need for less costly, reliable and sustainable power. The boundary condition is that under no circumstances can evacuation from such locations be considered. Moreover, fuel reloading should be avoided during the life of the reactor. Finally, transport of the reactor vessel and components to the site must be possible by ship, ice-road or aircraft. SEALER can meet all of these requirements.
