TerraPower’s innovative Natrium nuclear project , designed in collaboration with GE-Hitachi, has been granted approval by the Wyoming Industrial Siting Board . This permit, focused on non-nuclear activities, marks a critical step forward in constructing the first plant of its kind, located near a disused coal-fired power plant in Kemmerer, Wyoming.

Key permits for the energy future

The permit covers construction of the non-nuclear facilities, including the energy island that will house the molten salt storage tanks and turbines. TerraPower plans to begin construction in 2025 , aligning with the U.S. Department of Energy’s schedule under the Advanced Reactor Demonstration Program (ARDP) .

This development underscores the collaboration between the public and private sectors, and Wyoming’s determination to lead the transition to sustainable energy sources. The company has highlighted the importance of this regulatory process. “ It is a testament to the work of our team ,” said Chris Levesque, president and CEO of TerraPower.
