Wyoming

TerraPower is building its first reactor near the site of a retiring coal facility in Kemmerer, Wyoming, in a joint effort with the U.S. Department of Energy's Advanced Reactor Demonstration Project.

The Natrium Reactor is more than an idea

It is the only advanced, non-light water, reactor in the Western Hemisphere being built today to meet the challenges of the clean energy transition.

Currently under construction near a retiring coal plant in Kemmerer, Wyoming, the Natrium plant is proof that nuclear will play a critical role in combating climate change globally.

It will also provide key support to this historic energy producing community's local economy for decades to come.

Site Selection

The site was selected after a significant search including four finalist communities in Wyoming. The Natrium project team evaluated a variety of factors when selecting the site of the future Natrium plant. These included local community support, the physical characteristics of the site, the ability to obtain a license from the U.S. Nuclear Regulatory Commission (NRC) for the site, access to existing infrastructure and the needs of the grid.

TerraPower's technical teams spent five months visiting each community, collecting data and evaluating this information against regulatory and project requirements.

The project will employ approximately 1,600 workers during peak construction of the plant in Kemmerer. Once the plant is operational, about 250 workers will support day-to-day activities, including plant security. Those jobs will be in the community for many decades to come once the reactor is operational.

“Our producers stand ready, willing, and able to safely provide vital fuel.”

This is an exciting opportunity for Wyoming to open a new chapter in the nuclear power industry. Advanced nuclear generation clearly fits the bill for zero-emission, reliable and dispatchable electricity necessary to power our country into the future. Wyoming is the nation's leader in the production of domestic uranium. Our producers stand ready, willing and able to safely and responsibly provide the vital fuel for America's next generation of nuclear power.

“Due to the Natrium plant, the prospect of coming home and working in this field is possible.”

Growing up in Kemmerer, it became very apparent that in my desired job field, there weren't many job opportunities for me to come back to. I am extremely excited for the Natrium plant to come. It will not only boost our small-town economy but give my family and so many others the option to stay in Kemmerer. Due to the Natrium plant, the prospect of coming home and working in this field is possible.

“By selecting our community, TerraPower has opened a plethora of opportunities for positive, responsible, and sustainable growth throughout the whole community.”

TerraPower's selection of Southwestern Wyoming as the site for their new clean nuclear energy technologies has unleashed great opportunity to a rich and diverse area of Wyoming known for its energy and mineral production, fossil tourism, agriculture, and outdoor recreation. The new ideas from PacifiCorp and TerraPower, in the Kemmerer/Diamondville area, has brought an air of innovation in complementary industries such as clean energy recycling, hydrogen hub development, carbon capture and storage, but most importantly the expansion and new uses of natural gas, oil, and coal. By selecting our community, TerraPower has opened a plethora of opportunities for positive, responsible, and sustainable growth throughout the whole community.

“TerraPower's announcement to develop the Natrium Demonstration Reactor and to site the project in Wyoming was a seminal event in establishing new markets for other well-established industries within the state.”

TerraPower's announcement to develop the Natrium Demonstration Reactor and to site the project in Wyoming was a seminal event in establishing new markets for other well-established industries within the state. The announcement fueled optimism for Peninsula Energy, a Wyoming based uranium producer. Wyoming is a leader in uranium production and Wyoming's producers are now motivated to reestablish a meaningful domestic uranium production capacity. Congratulations and welcome to Wyoming!
