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.
One significant benefit of these would be the lack of transmission losses that plague massive plants which have to send electricity sometimes hundreds of miles. Having smaller units maintained by municipalities would be cheaper for cities far from major electrical plants.
You could make the same argument for renewables though, and they’re much, much more inexpensive.
Depends on many factors. Solar would be useful if the area had extensive terrain that could serve the city, however, in northern latitudes winter would be challenging with short days and low angle sunlight. If the situation allows, wind power could be useful, when the wind is blowing. The fantastic thing about these units is that they’ll crank out the KW day, night, no matter the season or location. They are not restricted to large generator farms with the scale of upkeep and maintenance they require. A city could be isolated in challenging remote areas and be self sustaining for their energy needs. These aren’t meant to be a “fix-all” solution for every situation, but they make tremendous sense in many applications where current methods are not ideal.
I get what you’re saying but we really should move away from needing power to be generated locally. High voltage DC can move power across huge distances with minimal loss - https://en.wikipedia.org/wiki/High-voltage_direct_current
We don’t need new nuclear in the US, we need the government to get off its ass and mandate an upgraded national grid so we can send power to wherever it’s needed. We already have the perfect conditions in the south for solar and the midwest prairies for wind, as well as offshore. Couple those with storage and there really is no case for SMRs outside of them being a way for fossil fuel companies to justify continuing to kill the planet while we wait for “the next big thing in nuclear power”.
I was curious, so I checked to see the current longest ultra-high voltage dc transmission line:
The Changji-Guquan ultra-high-voltage direct current (UHVDC) transmission line in China is the world’s first transmission line operating at 1,100kV voltage.
Owned and operated by state-owned State Grid Corporation of China, the 1,100kV DC transmission line also covers the world’s longest transmission distance and has the biggest transmission capacity globally.
The transmission line traverses for a total distance of 3,324km (2065 miles) and is capable of transmitting up to 12GW of electricity.
As a general rule of thumb, HVAC lines will be somewhere around 5-6% line loss per 1000kms, and HVDC somewhere around 3%/1000kms
