Radiant Selects Tennessee to Build World's First Mass-Produced Nuclear Generator Factory

Tennessee Gov. Bill Lee, Department of Economic and Community Development Commissioner Stuart C. McWhorter and Radiant officials announced today the company has selected Tennessee for a $280 million investment that will expand the company’s nuclear manufacturing and research and development (R&D) to Oak Ridge, Tennessee.

Through the project, Radiant will create 175 new jobs in Roane County that will directly support the development and mass production of Radiant’s Kaleidos. Upon completion of the facility, this machine will be the world’s first one-megawatt portable nuclear generator capable of generating power in remote areas and providing resilient power options for military bases or disaster-relief scenarios.

Radiant is the sixth company to locate in Tennessee utilizing the Nuclear Energy Fund.

The $50 million fund was in Gov. Lee’s recommended 2023-2024 budget and approved by the Tennessee General Assembly. An additional $10 million was allocated and approved in the state’s budget during both the 2024 and 2025 legislative sessions, bringing the fund’s total to $70 million since its inception.
