The collaboration focuses on a number of critical areas that are essential for scaling SEALER from prototype to full commercial readiness. These include the development of control room and operator environments, based on modern Human Factors Engineering principles, as well as the design of instrumentation and control systems to enable remote and autonomous operation. IFE will also contribute to the engineering of core mechanical components, such as shutdown assemblies and fuel handling systems, and support the design of radiation shielding to meet rigorous regulatory requirements.
Prototype development and component testing will be a central part of the work, helping to mature instrumentation of core, primary system and auxiliary systems, and reduce the technical risks associated with licensing and deployment. Together, Blykalla and IFE aim to speed up the transition from low technology readiness levels to the industrial standards needed for commercial rollout.
We’re proud to work with the renowned research institute IFE. Strengthening Scandinavian collaboration feels both vital and natural at a time when technological sovereignty is becoming central to industrial growth and long-term sustainability. Partnerships between leading actors can make all the difference in bringing new technologies to market and securing a clean energy future for our region.”
Jacob Stedman
CEO Blykalla
By combining Blykalla’s innovative reactor design with IFE’s world-leading expertise in nuclear systems engineering, the partnership aims to unlock the next stage in SMR deployment — turning advanced concepts into certified, buildable technology.
We’re pleased that our competence and expertise will be used in the next stage of the nuclear area. Partnership with Blykalla allows them to take research into innovation and allows us to get firsthand learning of future research gaps.”
Bjørn Axel Gran
Vice President at IFE Nuclear
The long-term vision is ambitious. Blykalla plans to deploy up to 1,000 SMRs by 2050, delivering 500 TWh of clean energy annually to industrial users that cannot rely on intermittent power sources. SEALER is designed to serve sectors such as hydrogen production, process heat, and pyrolysis, with the potential of significantly reducing global CO₂ emissions and securing industrial resilience and growth. Initial joint development will take place in Sweden and Norway, with further phases aligned to SEALER’s licensing and industrialization timeline.
About Blykalla
Blykalla is Sweden’s only developer of advanced SMRs, commercializing lead-cooled fast reactors for industrial use. Based on 20+ years of research, their SEALER technology is a compact 55 MWe unit designed to offer a safe, efficient, and scalable power solution. With a strong foundation within Sweden, Blykalla is well positioned to deliver Europe’s first advanced SMR, providing reliable and sustainable baseload energy to power AI and clean industries.
With strong backing from partners such as Uniper, ABB, OKG, and the Royal Institute of Technology, Blykalla is currently constructing their electrical prototype in Oskarshamn, Sweden. The company plans to achieve criticality for its first SEALER reactor by 2030 and begin serial production in the 2030s. Once deployed, Blykalla aims to generate up to 500 TWh of clean electricity annually, cutting global CO₂ emissions by 0.5 gigatons each year.
