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.

Continuous bench-plant operation for ∼4 months has resulted in the first recovery of 3 %-enriched uranium by means of a chemical-exchange process. This confirms the reduced development time and uranium adsorption band stability predicted by mathematical models, which are derived by application of mass transfer concepts to redox chromatography and extension of addition reaction equilibrium equations to include multiphase systems. Furthermore, it confirms the achievement of a reduction in stage time by >103 through catalytic acceleration of the isotope-exchange rate and employment of an adsorbent with a high adsorption/desorption rate.
