Our background 

LeadCold is a spin-off from the Royal Institute of Technology (KTH) in Stockholm, where we have designed lead-cooled reactor systems since 1996. Our competences include fast reactor core design, transient analysis, corrosion and materials science, nuclear fuel development, lead coolant chemistry, radiation damage and severe accident analysis. At KTH, we have access to laboratories for lead corrosion studies, nuclear fuel manufacture, heavy liquid metal thermal hydraulics and severe accident experiments. The research at KTH is made in close collaboration with Swedish nuclear materials industry. Funding for this research is currently obtained from VINNOVA (The Swedish Innovation Agency).


The company 

LeadCold Reactors (Blykalla Reaktorer) was founded in 2013 as a joint stock company with its basis in Stockholm. Our Canadian subsidiary is registered in Alberta, Northwest Territories and Nunavut.
