SMR FOR NORTHERN EUROPE

N- May 1, 2025 - Swedish nuclear energy company Blykalla and Norway’s Institute for Energy Technology (IFE) have agreed a strategic collaboration to accelerate the technical development of Blykalla’s SEALER small modular reactor (SMR).

Blykalla, founded in 2013, is a spin-off from the KTH Royal Institute of Technology in Stockholm. Its SMR prototype SEALER (Swedish Advanced Lead-cooled Reactor) design is a fast compact reactor with passive safety. Each reactor will have a 55 MWe capacity, which can be increased by installing multiple units at the same location. The reactor is designed with the smallest possible core that can achieve criticality in a fast spectrum using 19.9% enriched nitride fuel.

The collaboration focuses on a number of critical areas seen as 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.
