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.

Transition boiling heat transfer data from Semiscale Mod-3 gravity feed reflood experiments have been compared to existing transition boiling correlations. The existing correlations were found to be inadequate for predicting the Semiscale rod bundle data; therefore, a new correlation for transition boiling was developed. The new correlation is applicable for boiling water with stainless steel, electrically heated vertical rods in a pressure range of 138 to 414 kPa. When the new transition boiling correlation is combined with the Berenson film boiling correlation, a good fit to Semiscale reflood data results.
