- Doosan Enerbility signed a contract with NuScale to manufacture an upper reactor coolant system for a commercial small modular reactor.
- A separate X-energy order adds steam-generator component work for the Xe-100 reactor program in the United States.
- The agreements strengthen Doosan Enerbility's role as a nuclear equipment manufacturer while project execution remains the next investor focus.
Doosan Enerbility signed a contract with NuScale Power on October 29 to manufacture an Upper Reactor Coolant System for a commercial small modular reactor, according to a Doosan Group press release. The agreement moves the cooperation from material preparation into fabrication of a First Article for NuScale's Power Module.
From preparation to fabrication
The Upper Reactor Coolant System forms the upper section of the reactor pressure vessel and contains reactor coolant under high-temperature and high-pressure conditions. Doosan said production will take place at its reactor manufacturing facility in Changwon, South Korea, extending a relationship with NuScale that began in 2019.
NuScale's design is the first small modular reactor design to receive approval from the U.S. Nuclear Regulatory Commission, the company said. For Doosan, the contract creates a manufacturing milestone, but future commercial value will depend on production execution and follow-on orders.
Second advanced-nuclear program
Doosan is also participating in X-energy's Xe-100 supply chain. In a November 4 release from X-energy, the companies announced the first procurement of steam-generator tubing for the Xe-100 project. Alleima will supply specialized tubing, while Doosan will bend it into helical coils for the steam generator.
The X-energy release said the component is intended for a proposed four-unit plant in partnership with Dow in Texas under the U.S. Department of Energy's Advanced Reactor Demonstration Program. It also said Doosan has supplied 34 reactor vessels and 124 steam generators to nuclear facilities worldwide.
What investors should watch
The two programs broaden Doosan Enerbility's exposure to advanced nuclear manufacturing and connect its facilities with U.S. reactor developers. The next relevant milestones are component production, delivery schedules, regulatory progress and conversion of development activity into firm commercial orders.
Business and competitive position
Doosan Enerbility is based in South Korea and supplies power-generation and energy equipment, with a particular focus on nuclear plant components and small modular reactor manufacturing. Its business also includes heavy power equipment such as gas turbines and related systems. In power-generation equipment, it competes with larger global suppliers such as GE Vernova and Siemens Energy, while Mitsubishi Heavy Industries is another established rival in nuclear and turbine equipment; Doosan's position is more specialized around nuclear manufacturing and its Korean industrial base.
