Kärnfull Next has submitted an application to build a power plant based on small modular reactors in the municipality of Valdemarsvik in Östergötland county in southeastern Sweden. It is the first application under the country’s new Act on Government Approval of Nuclear Facilities.

The application - submitted by project company ReFirm Målma AB - covers a planned small modular reactor (SMR) campus in Valdemarsvik, and was formally submitted to Johan Britz, Minister for Employment and acting Minister for Climate and the Environment.
The SMR campus in Valdemarsvik is initially planned to host between four and six small light water reactors, adding between 10-15 TWh of electricity generation per year. In February 2025, Kärnfull Next announced it had secured land rights for the Valdemarsvik project. The property includes areas that were identified as suitable for nuclear power in studies going back as far as the 1970s.
"This is a clear step from concept to formal permitting," said Kärnfull Next CEO Christian Sjölander. "Sweden needs new dispatchable, fossil-free power – particularly in the south – and this application shows that real projects are now moving forward."
The Valdemarsvik project would be part of Kärnfull Next's ReFirm South SMR programme, aiming to expand carbon-free and dispatchable energy production across southern Sweden.
