The inauguration of Tube Mill 2026 is a direct response to the growing global interest in nuclear power. The expansion includes the upgrade and reopening of one of Alleima’s production facilities for steam generator tubes. The new facility increases Alleima’s production capacity by approximately 60%, and the order base is solid, extending well into the future. The entire project has been completed according to plan and will be operational during 2026.
“The opening of Tube Mill 2026 marks an important milestone for Alleima. By upgrading and reopening our tube mill, we strengthen our ability to meet the growing demand within the nuclear segment, both for conventional nuclear power plants and for small modular reactors. This is a central part of our strategy and demonstrates that we are a leading supplier of high-technology products based on quality, reliability, and long-standing industry experience,” says Göran Björkman, CEO of Alleima.
For more than 60 years, Alleima has supplied critical components to the nuclear industry worldwide. The company already has around 300 employees directly involved in its nuclear operations, a number that is now increasing by nearly 100 employees. In addition to conventional nuclear power, the company sees strong potential for SMRs. Recently, major technology companies have also begun to show interest in nuclear power for their data centers driven by the need for large amounts of stable and fossil-free electricity around the clock.
Among those present at the event were several key players in the nuclear industry, including Doosan Enerbility, NuScale Power, Rolls-Royce SMR, and Westinghouse.
“Today, we have customers from all over the world here in Sandviken. This demonstrates that we have established ourselves as a reliable, stable, and long-term partner, manufacturing world-leading products for extremely demanding environments. Strong and close collaboration with our customers is essential for us, and we are therefore very pleased to celebrate this together,” says Carl von Schantz, President of the Tube Division at Alleima.
Alleima supplies fuel cladding tubes, steam generator tubes, and nuclear-grade components, and also conducts research on tubing for future cooling technologies.
