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.

Estimation of gap conductance in nuclear reactor fuel rods requires values for thermal accommodation coefficients of several gases on Zircaloy, uranium-dioxide, stainless steel, and other surfaces. These values for UO2 have now been obtained by observing cooling rates of a UO2 sphere suspended in the several gases in a manner similar to the authors’ previous work on Zircaloy-2. These measurements are on so-called “engineering” surfaces, and no special attempt other than mild baking under high vacuum pumping was used to clean the surfaces.
