TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.
The American Nuclear Society provides statements which reflect the Society's perspectives on issues of public interest that involve various aspects of nuclear science and technology. Position statements are prepared by key members whose relevant experience or publications inform the documents and then the documents are reviewed by ANS committees and divisions. The final position statements are approved by the Board of Directors.
