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.

At 1273 K, the principal products in the reaction of uranium carbides with Cr-Fe-Ni alloys are UNiC2 and the Laves phase U(Fe,Ni,Cr)2. At 973 K, the principal products are UNi5 and (Cr, Fe)7C3. At the lower temperature, reaction with uranium monocarbide is limited by the rate of formation of UNi5. Liquid formation was observed in the UC Type 316 stainless system at 1292 ± 8 K and at 1351 ± 12 K in the UC Inconel 718 system.
