Blykalla

Blykalla develops the SEALER, a 55 MWe lead-cooled small modular reactor designed for factory serial production and co-location with industrial sites and data centers. The company's core technical claim is a self-healing aluminum-alloyed steel that resists corrosion from liquid lead, which it says has been developed over more than 25 years of research.

The company states it is taking lead-cooling to market and is working with industries that will build and host its reactor parks. Its public materials mention a partner inquiry channel for supply chain and partnership opportunities and an investment channel for fundraising. The website does not describe specific customer contracts or revenue model.

The site lists Stockholm and Austin (US) job locations and mentions a US project development function. Open roles (27 listed) cover nuclear engineering, plant engineering, safety, fuel and materials, regulatory and finance, with most roles in Stockholm and several in Austin. Founders include professors from KTH Royal Institute of Technology.
