Partners with Sweden's Alleima to handle special steel tube coil processing
First deployment at four-unit SMR site for Dow chemical plant in Texas
Doosan Enerbility has signed a contract to supply steam generator components for small modular reactors (SMRs) with X-energy, a US SMR developer, and Alleima, a Swedish specialty steel manufacturer. With the order, Doosan Enerbility will directly supply key equipment for X-energy's next-generation SMR commercialization project, further strengthening its position in the global nuclear value chain.
According to an official announcement by X-energy on Nov. 4, the three companies signed the first procurement contract for steam generator tubes to be used in the Xe-100, a next-generation SMR model under development by X-energy. Alleima, a specialty steel company that has supplied major components to the nuclear market since 1964, will produce special stainless steel tubes using high-temperature alloy technology for the project. Doosan Enerbility will handle the processing of bending the tubes into helical coil shapes to complete the final components using its proprietary manufacturing technology.
The helical coils play a central role in safely removing heat from the Xe-100 steam generator and generating high-temperature steam of up to 565 degrees Celsius. This technology enables a single SMR to supply both electricity and industrial high-temperature process heat simultaneously. The components to be produced will be deployed at the first four-unit Xe-100 power plant to be built at a Dow chemical plant in Texas under the US Department of Energy's Advanced Reactor Demonstration Program (ARDP).
The order is an extension of the long-standing partnership between Doosan Enerbility and X-energy. The two companies began technical cooperation for commercial production of Xe-100 components in 2021, and in 2023 Doosan Enerbility made a direct equity investment in X-energy. In December last year, they signed a preliminary reservation agreement for the supply of major equipment including 16 sets of Xe-100 reactor pressure vessels and steam generators, accelerating preparations for commercialization.
As power demand from global big tech companies has recently increased, the SMR market is growing rapidly. X-energy is building a new nuclear pipeline of more than 11 gigawatts (GW) in the United States and the United Kingdom in cooperation with Amazon and Energy Northwest. As next-generation reactor technology enters the commercialization stage and the importance of reliable component partners grows, Doosan Enerbility's capabilities—having supplied 34 reactors and 124 steam generators to nuclear facilities worldwide—are serving as a critical pillar in minimizing supply chain risks in X-energy's large-scale commercialization plans.
Jess Walker, chief supply chain officer at X-energy, said, "Behind every component of the Xe-100 is a team of experts who know how to make it work," adding, "We will advance the technology to commercial scale based on the expertise of Alleima and Doosan Enerbility, world-leading component manufacturers."
