New-wave reactor technology could kick-start a nuclear renaissance — and the US is banking on it | CNN

The US government and companies are plowing billions into small modular reactors. China is leading in the tech, Russia is making almost all the fuel. The US is playing catch-up.

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.

    here https://www.pnas.org/doi/full/10.1073/pnas.1610381114 we can talk about this, feel free to put forward counter arguments, the gist of the cited paper is that previous studies claiming 100% renewable baseload is possible requires sketchy manipulation of the expected demand as well as currently unavailable storage technology on an almost impossible scale. We’re working on all kinds of storage solutions but the reality is we’re not there yet. I’m rooting for molten salt storage or compressed gas storage rather than ramping up more lithium battery storage. Flow batteries are promising as well, but in any case we won’t have enough storage or transmission capability to have a 100% renewable baseload in the next couple of decades.
