Curtiss Wright Advances to Prototype Manufacturing for Xe 100 Reactor Systems

Curtiss Wright has moved from design into prototype manufacturing for two major systems supporting X energy’s Xe 100 high temperature gas cooled reactor. The transition marks a significant milestone in the company’s work on advanced energy technologies that share engineering commonalities with aerospace grade systems, including high reliability components, precision manufacturing, and rigorous safety architectures.

Prototype Helium Circulator System Enters Manufacturing and Test Phase

The Helium Circulator System is a core element of the Xe 100 reactor’s thermal management architecture. It is responsible for circulating helium through the primary loop to transfer heat from the reactor core to the steam generator. This process enables electrical power generation, industrial heat applications, and residual heat removal.

Curtiss Wright’s move into prototype manufacturing brings the system closer to full scale validation. The company noted that the work reflects its commitment to advancing technologies that require high integrity engineering and long term operational reliability, capabilities that are also foundational across aerospace propulsion, thermal management, and power systems.

Safety and Control System Prototypes Begin Production

Curtiss Wright has also begun prototype manufacturing of the Reactivity Control and Shutdown System. This system regulates reactor temperature and provides an independent shutdown mechanism. It includes two separate rod banks with associated control rod drive mechanisms and control electronics.

The company emphasized that the system is engineered to deliver predictable, redundant, and fail safe performance. These characteristics mirror the design principles used in aerospace flight control, actuation, and safety critical subsystems, making the program relevant to aerospace readers tracking cross domain engineering advancements.

Supporting X Energy’s Deployment Strategy

Curtiss Wright is a key partner in X energy’s global deployment plans for the Xe 100 reactor. The reactor is designed to deliver 80 megawatts of electric power per unit, or 320 megawatts for a four unit plant. It is intended to provide clean, resilient baseload power for industrial operations, data centers, and grid applications.

X energy is developing its first Xe 100 plant at Dow’s Seadrift Operations site in Texas and is advancing plans for up to twelve units with Energy Northwest in Washington state. These projects are part of a broader initiative to deploy up to five gigawatts of Xe 100 capacity.

Curtiss Wright’s Broader Role in High Reliability Engineering

Curtiss Wright continues to expand its portfolio of engineered systems that support aerospace, defense, and advanced energy markets. The company’s work on the Xe 100 program leverages its expertise in precision manufacturing, safety critical systems, and long duration program support.

Leadership stated that the transition to prototype manufacturing represents meaningful progress and reinforces the company’s commitment to innovation in high reliability technologies.
