Blykalla AB was founded in 2013 by Janne Wallenius, Peter Szakalos, and Jesper Ejenstam as a spin-off from the Royal Institute of Technology in Stockholm, Sweden, where Janne Wallenius has carried out research on design and safety analysis on lead-cooled reactor systems since 1996.

The research brought together insights from fast reactor design, transient analysis, corrosion and materials science, nuclear fuel development, lead coolant chemistry, radiation damage, severe accident analysis, nuclear construction, and operation of nuclear power plants to create a unique reactor design that provides safe and sustainable baseload energy. 

We work toward a future with 100% clean energy. Currently, the world is dependent on carbon-based baseload energy. That is why our goal is to construct and deploy 1 000 SMRs. Together they will produce close to 500 TWh clean electricity annually. If successful, we will avoid 0.5 gigatons of C02 - or 1% of global emissions - every year.

Our lead-cooled fast reactors (LFRs) will be used for electricity, heating, and industrial applications such as production of hydrogen, HVO, syngas, and biochar. By targeting otherwise hard-to-abate sectors we contribute to decarbonization throughout the industrial value chain.
