Blykalla applied for Swedish government financing to support a proposed advanced nuclear reactor park with up to 330 megawatts of capacity, the company said Friday.
The Norrsundet project, located about two hours north of Stockholm, would become Sweden's first proposed advanced nuclear facility and would operate six SEALER lead-cooled advanced modular reactors, according to Blykalla.
The planned reactor park in Gavle municipality could generate an estimated 2.76 terawatt-hours of electricity annually, the company said.
Under Sweden's nuclear financing framework, introduced on Aug. 1, 2025, Blykalla submitted the first application for an advanced nuclear power project, according to the company.
As Sweden's electricity needs continue to rise, Chief Executive Officer Jacob Stedman said the project would help deliver the clean baseload power required to support industrial electrification and the expansion of digital infrastructure.
Driven by artificial intelligence, data centers, and industrial electrification, Sweden could see electricity demand double by 2045, Blykalla said.
The financing model combines government loans, a two-way Contract for Difference, and a risk-and-profit-sharing mechanism, while authorities will negotiate key terms for each project and submit them for European Commission review.
Using proprietary aluminum-alloyed steels and lead-cooling technology, Blykalla designed its SEALER advanced modular reactor to withstand liquid lead and support the commercial deployment of lead-cooled fast reactors, the company said.
Blykalla will negotiate financing terms with the Swedish government while advancing permitting under Sweden's Environmental Code and Nuclear Technology Act, the company said.
