Alleima, a Swedish company, is expanding its capacity to meet the growing demand for nuclear energy. The inauguration of the Tube Mill 2026 production facility in Sandviken, Sweden, marks a significant milestone for the company as it prepares to supply high-technology products for conventional and small and advanced reactors. The new facility, which includes the upgrade and reopening of the production facility for steam generator tubes, increases the company's capacity by 60%.
The CEO of Alleima, Göran Björkman, emphasized the importance of this expansion in meeting the growing demand within the nuclear segment. He stated that the company is a leading supplier of high-technology products based on quality, reliability, and long-standing industry experience. Björkman also mentioned that Alleima has already delivered some contracts for small modular reactors (SMRs) and is involved in research and development with several advanced modular reactor developers.
Carl von Schantz, President of the Tube Division, highlighted the significance of the investment in research and development. He explained that the new generation of reactors requires materials that can handle different cooling methods and technologies. Von Schantz added that Alleima has established itself as a reliable, stable, and long-term partner, manufacturing world-leading products for extremely demanding environments. The company is increasing its capacity by around 60% to meet the rapidly growing global demand.
The inauguration of the facility was attended by several prominent companies, including Doosan Enerbility, NuScale Power, Rolls-Royce SMR, and Westinghouse. Alleima, previously known as Sandvik Materials Technology, has been involved in the nuclear energy supply chain for more than 60 years. In addition to steam generator tubes, the company also supplies nuclear fuel cladding tubes and other nuclear-grade components.
Since 1964, Alleima has supplied tube bundles to more than 400 steam generators in over 20 countries and has provided more than 60,000,000 meters of nuclear fuel tubes to over 100 reactors. This extensive experience and track record make Alleima a trusted and reliable partner in the nuclear industry. The company's expansion and commitment to meeting the growing demand for nuclear energy are crucial for the future of the industry and the transition to cleaner and more sustainable energy sources.
