Kärnfull Next

We pave new roads to get new nuclear built. Not by doing easy things, but by doing the right things – at the right time. That’s Kärnfull Next – a Studsvik company.

Kärnfull Next develops sites and early-stage projects for small modular reactors (SMRs) in the Nordic region and has established itself as one of Sweden’s most active private-sector players in new nuclear development. The company works with site selection, project development and early permitting processes in collaboration with international technology vendors, industrial partners and local stakeholders.

Studsvik took a significant step in its strategic development during the spring of 2026. The acquisition of Kärnfull Next was announced in March and successfully completed on May 10. The completion of the transaction marks the beginning of a new era for Studsvik as a full-cycle nuclear platform, spanning services for the existing reactor fleet, new build development, operations support, and decommissioning.

As part of this expansion, Kärnfull Next submitted an application on March 23 related to the development of small modular reactors (SMRs) in Valdemarsvik under Sweden’s updated nuclear legislation. On May 25, Studsvik submitted a second application to build up to 1,400 MW of new nuclear power generation at its home site in Nyköping.

Together, these milestones represent a major step forward in Studsvik’s ambition to support and drive the next generation of nuclear energy development in Sweden.
