Company Overview
Blykalla is a Swedish advanced nuclear company commercialising the SEALER, a lead-cooled small modular reactor aimed at delivering reliable low-carbon power for industrial users and data centres. The company is moving from research and development toward deployment, with a planned reactor park in Sweden and pre-application engagement with the United States Nuclear Regulatory Commission.
