Projects
Bechtel is constructing the facilities that will enable our partner TerraPower in building the first Natrium Plant and delivering the future of nuclear energy. By breaking ground in 2024, Bechtel continues to play a pivotal role in shaping the future nuclear landscape.
In 2025, Bechtel teams advanced through construction milestones on the Test and Fill Facility (TFF). We successfully poured the concrete for the TFF foundation and erected the steel framework. The TFF will serve as critical infrastructure, laying the groundwork for safe, efficient operations and long-term success at the Kemmerer site.
The project also awarded 44 major procurements and contracts with a total value of $100 million, including the Molten Salt Tank design, the Steam Turbine Generator, the Steam Generator System, and the Mechanical, Electrical, and Piping subcontract for the TFF. The Natrium Plant’s design represents a major leap forward in sustainable power generation. Bechtel is proud to help bring this visionary project to life, shaping the future of energy for generations to come.
Bechtel is partnering with TerraPower on the first-of-a-kind Natrium plant in Kemmerer, Wyoming. The Natrium Reactor is a TerraPower & GE Vernova Hitachi Nuclear Energy Technology. The project is a part of the U.S. Department of Energy’s Advanced Reactor Demonstration Program (DOE Cooperative Agreement No. DE-NE0009054). With a sodium fast reactor, integrated energy storage and flexible power production, the Natrium plantoffers carbon-free energy at a competitive cost and is ready to integrate seamlessly into electric grids with high levels of renewables. Bechtel adds current and unmatched experience managing and executing large nuclear projects to the team.
With a legacy dating back to the 1950s, Bechtel has been a driving force in the evolution of nuclear power. Having designed, built, or provided services to over 80 nuclear reactors in the United States and 150 worldwide, Bechtel’s history in nuclear power is a testament to its unwavering commitment to excellence and innovation. From delivering next generation reactor technologies to setting industry standards for safety and efficiency, Bechtel has played a pivotal role in shaping the global nuclear landscape.
Set against the backdrop of a retiring coal plant in Kemmerer, Wyoming, this advanced energy demonstration seeks to validate the design, construction, and operational features of the Natrium plant. As the nexus of TerraPower and GE Vernova Hitachi technology, the Natrium plant represents a leap forward in sustainable power generation. The project will bring a commercial operating, advanced nuclear reactor online that will deliver carbon-free, reliable power to the electric grid and provide good-paying jobs in Wyoming for decades to come.

Bechtel brings decades of experience and expertise to the table. With a proven track record in delivering complex infrastructure projects, Bechtel is uniquely positioned to tackle the challenges inherent in constructing a first-of-its-kind nuclear facility. From meticulous planning to precise execution, Bechtel’s commitment to excellence ensures that the Natrium plant will set new standards for safety, efficiency, and innovation.
The Natrium plant stands as a testament to our commitment to innovation in nuclear construction. By pioneering our Digital Delivery approach, we are revolutionizing the nuclear industry’s landscape. This cutting-edge methodology, now being implemented in our latest projects such as the Natrium plant and the Poland AP1000 Project, marks a paradigm shift.
Our approach integrates advanced technologies like 3D Building Information Modeling (BIM) within a Central Data Environment, seamlessly streamlining workflows from design to procurement, construction, and handover. This digital framework enables electronic creation and completion of construction work packages, including digital signatures and real-time updates, eliminating the inefficiencies of paper-based processes. Digital delivery and innovation help to increase time on tools, improving productivity in the field, and fostering transparency with our customer along with creating efficiencies that lead to successful completion and operations.
Join us as we embark on this transformative journey towards a sustainable energy future with the Natrium plant. Together, we can shape a world where energy knows no bounds.
