Alleima's Nuclear Expansion: Meeting the Growing Demand for Advanced Reactors (2026)

Alleima, a leading nuclear energy supplier, is gearing up to meet the growing demand for nuclear power, both from conventional plants and the emerging small and advanced reactors market. The company's strategic move involves expanding its production capacity by 60% through the inauguration of the Tube Mill 2026 facility in Sandviken, Sweden. This facility includes the upgrade and reopening of the steam generator tube production line, which has been dormant for a decade.

The CEO of Alleima, Göran Björkman, emphasizes the significance of this expansion in the context of the nuclear industry's evolution. He states, '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 (SMRs).' This move underscores Alleima's commitment to being a leading supplier of high-technology products, emphasizing quality, reliability, and a deep-rooted industry experience.

The company's involvement in research and development with various advanced modular reactor developers is particularly noteworthy. Björkman mentions that they have already delivered contracts for SMRs and are actively engaged in R&D with developers utilizing different technologies, including helium, lead, sodium, and molten salt. This diverse portfolio positions Alleima as a versatile player in the nuclear energy sector, capable of adapting to the evolving needs of the market.

Carl von Schantz, President of the Tube Division, highlights the importance of this R&D investment for customers. He explains, 'If you're going to build the new generation reactors, the advanced reactors, you need to ensure that you have the right material in the tubes to handle the different cooling methods and technologies.' This emphasis on innovation and adaptability is crucial in a rapidly changing industry.

The inauguration of the facility attracted prominent companies such as Doosan Enerbility, NuScale Power, Rolls-Royce SMR, and Westinghouse. This gathering underscores the collaborative nature of the nuclear industry and the importance of established partnerships. Von Schantz remarks, '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.'

Alleima's history in the nuclear energy supply chain, dating back over 60 years, further solidifies its position as a trusted and experienced player. The company's expertise extends beyond steam generator tubes, as it also supplies nuclear fuel cladding tubes and other nuclear-grade components. Since 1964, Alleima has supplied tube bundles to over 400 steam generators in more than 20 countries and has produced over 60,000,000 meters of nuclear fuel tubes for over 100 reactors. This extensive track record positions Alleima as a key enabler in the global nuclear energy landscape.

In conclusion, Alleima's strategic expansion and commitment to innovation position the company well to capitalize on the growing demand for nuclear power. With a strong focus on quality, reliability, and adaptability, Alleima is poised to play a pivotal role in the development and expansion of the nuclear energy sector, both in conventional and advanced reactor technologies.
