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.

    Except long distance power transmission losses are not minimal. Depending on many factors, losses can easily be in the 5% - 10% range. With the amount of energy going through those wires, that’s HUGE. The additional complexity and inefficienies of relay stations, all add up. Having worked in the power sector for nearly a decade, I knew engineers who were celebrated in being able to squeeze an improvement of tiny fractions of % efficiency, as that resulted in millions of dollars saved throughout the year.
