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.

Oxidation studies have been carried out on 11.5 to 12.0 g/cm3 density uranium monocarbide microspheres and on mixed 11.96 to 12.04 g/cm3 density uranium-plutonium carbide pellets under various oxygen partial pressures in the 550 to 745 K temperature range. Oxidation of UC and (U,Pu)C produced a U3O8 [oxygen-to-metal ratio (O/M) = 2.66] and (U,Pu)O2 (O/M = 2.15), respectively, with a carbon content of <600 ppm. The surface area of the resultant oxides as determined by the Brunauer-Emmett-Teller method are 1 to 2 and 4 to 5 m2/g, respectively. The oxidized products were suitable for wet and dry recycle.
