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.

Total hemispherical emissivity of Alloy 617 was measured for applications in very high temperature reactors with apparatus based on ASTM Standard C835-06. The emissivity data were obtained for the following surface conditions: (1) as-received (rolled sheets) from manufacture, (2) sandblasted with aluminum oxide beads, (3) oxidation in air at temperature of 1153 K, and (4) coated with graphite powder. For the as-received Alloy 617, emissivity increased from 0.26 to 0.34 over the temperatures 593 K to 1164 K. Sandblasting Alloy 617 with alumina beads increased the emissivity to 0.46 to 0.73 in the temperature range 600 to 1300 K (emissivity increased further when higher grit size beads were used). The oxidation of Alloy 617 gave a slight increase in emissivity from 900 to 1250 K with larger increases above 1100 K. Coating of graphite onto as-received and 60-grit sandblasted increased the emissivity by roughly 0.12 and 0.20, respectively, over the measured temperature range.
