The technological breakthrough developed by KTH in cooperation with the Swedish steel industry is a new aluminum and zirconium alloyed steel (Fe-10Cr-4Al-Zr) that provides adequate long-term performance in hot lead. After 19,000 hours of exposure at 550 C, the material appears to be in like new condition. By limiting operating temperature to 450 C the designers are confident that SEALERs using the new alloy will be able to operate reliably for as long as 30 years. That confidence, of course, will be something that LeadCold will have to demonstrate to the satisfaction of the regulatory agency. On photo Lead corrosion laboratory: >19000 hour exposure of Fe-10Cr-4Al-Zr alloys at 550°C completed. Optimised alloys in perfect condition after exposure.
LeadCold and Essel Group ME have announced an agreement for a $200 million (USD) investment to build uranium-fueled power sources. Their systems, trademarked SEALER, are designed to compete with diesel generators to supply dependable power to communities and industries in remote areas of the world. SEALER (Swedish Advanced Lead Reactor) is a fast spectrum nuclear reactor that uses low enriched uranium oxide fuel (19.5%) cooled by molten lead. TheRead more
