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.

Simulated high-level commercial fluidized-bed calcine was treated to form sintered glass-ceramics (SGC) by sintering compacted mixtures of calcine with aluminosilicate fluxes at temperatures ranging from 965 to 1070°C. Products are resistant to impact and thermal shock and exhibit leach rates of 10−5 to 10−9 g/(cm2 day). Up to 67 wt% calcine is used, giving waste volumes as low as 0.040 m3 /MTU reprocessed. Storage centerline temperatures up to 800°C appear feasible. A conceptual process in which SGC is molded into thin-walled containers for processing and canister loading is proposed.
