Kärnfull is the Nordic energy group that put nuclear back at the heart of the clean-energy conversation.

​

We built Scandinavia's first 100% nuclear electricity supplier — and one of Sweden's first private-sector SMR project developers. In 2026 that developer, Kärnfull Next, joined Studsvik (Nasdaq Stockholm: SVIK) to take Sweden's new-build programme forward with the industrial and engineering muscle to see it through.

​

Today, Kärnfull Group remains home to Kärnfull Energi — connecting the everyday electricity use of tens of thousands of Swedes and Danes to guaranteed, 100% fossil-free nuclear power.
