Rolls-Royce brings small nuclear power to Sweden after forty years

Published on June 17, 2026 | Translated from Spanish

Rolls-Royce has secured a multi-billion dollar contract to install three small nuclear reactors in Sweden, the first in more than four decades. These units will generate electricity for homes and industries in the south of the country, offering a cleaner and more stable energy source. The bet reduces dependence on fossil fuels and marks a firm step towards a safer and more sustainable electricity supply for the region.

Small reactors, big technical impact ⚛️

These small modular reactors (SMRs) use pressurized water technology, similar to that of British nuclear submarines. Their compact design allows for mass production and on-site assembly, reducing construction times and initial costs. Each unit generates about 470 MW, enough to supply hundreds of thousands of homes. Additionally, they incorporate passive safety systems that minimize risks, facilitating regulatory approval in demanding countries like Sweden.

Less smoke, more cold cuts (of salmon) 🐟

Swedes will have to get used to not seeing those smoking chimneys that brighten up the winter landscape so much. That said, they will be able to plug in their hair dryers and baby cribs without the power grid complaining. And if things go wrong, there's always plan B: lighting homes with Ikea candles while calling the Rolls-Royce technician. Small nuclear power promises a lot, but it doesn't include flat-pack furniture.
