Off the Siberian coast, not far from Alaska, a Russian ship has been docked at port for four years. The Akademik Lomonosov, the world’s first floating nuclear power plant, sends energy to around 200,000 people on land using next-wave nuclear technology: small modular reactors.
This technology is also being used below sea level. Dozens of US submarines lurking in the depths of the world’s oceans are propelled by SMRs, as the compact reactors are known.
SMRs — which are smaller and less costly to build than traditional, large-scale reactors — are fast becoming the next great hope for a nuclear renaissance as the world scrambles to cut fossil fuels. And the US, Russia and China are battling for dominance to build and sell them.
I’ve been following the situation in Canada. Afaik the closest we are to getting SMRs is a plan to supplement power production at the Darlington, Ontario CANDU plant using SMRs of the GE Hitachi design. The utility is seeking regulatory approval on the first of 4, but they haven’t broken ground yet to the best of my knowledge. Each would put out up to 300 Mw, so I guess the completed project would add 1.2 Gw to the grid.
Ontario gets around half its power from nuclear, and the current provincial government is gung-ho on building more capacity. While I am not opposed to the idea (they would need to build more anyway just to maintain that ratio in coming decades), the fact that it comes at the heels of them cancelling nearly every renewable energy project at the beginning of their term adds a sour note. These included those that were actually under construction, and tax money had to foot the bill on broken contracts. It was flabbergasting. I am cautiously optimistic about SMRs but they are still vapourware for the most part at this time.
It’s a known tactic of the fossil fuel industry (and the politicians they own) to push SMRs as a delay tactic, so they can continue to make money from coal and gas for a bit longer. And conservative parties get to play culture war over it, which we know they love to do.
If something real comes out of it then great, but you can’t plan an energy transition based on a technology that isn’t proven yet.
That just shows that nuclear is nothing but a smokescreen for perpetuating fossil fuels. First they cancel the renewable projects because they have all those fancy new nukes now. Then the nukes never pan out (as they do). Oh shucks, guess we have to keep using coal.
