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.

An approach to balancing the nuclear fuel cycle equation utilizing the Advanced Liquid Metal Reactor System (ALMRS) using synergistic components currently under development by the United States Department of Energy is described. These components include the modular, passively safe ALMR design; the Integral Fast Reactor (IFR) metal fuel cycle; and the processing of LWR spent fuel to use as startup fuel for the ALMRs. Each of these components will be briefly described along with an overall system perspective, including potential optional approaches. Assessments of beneficial impact of the ALMRS in the United States will be presented based on the United States Department of Energy National Energy Strategy energy use growth scenarios through the mid-21st century. Potential applications in other international energy infrastructures will also be considered. Preliminary evaluation of the economics of this balanced approach leads to the conclusion that the concept is feasible; thus the approach appears attractive from both resource management and overall system economics perspectives.
