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.

Eight large-scale spray experiments have been made in the 26 500 ft3 Containment Systems Experiment (CSE) vessel. In each experiment a major parameter was changed. Spray fluxes ranged from 0.025 to 0.3 gal/(min ft2). Spray drop size was 770- or 1210-µm mass median diameter (MMD). Atmospheric condition was air at room temperature and pressure or steam-air initially at 250°F, 48 psia. Three types of spray solutions were used: boric acid, pH 5; boric acid plus NaOH, pH 9.5; and boric acid plus 1 wt% Na2S2O3 with NaOH added to pH 9.5. The only major parameters not varied were the drop fall height (38 ft) and the gas-to-liquid volume ratio (∼80).
