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.

Heat fluences of 1–10 MJ/m2 and greater over 0.1–1 msec pulse durations are expected on the surfaces of plasma-facing components in large tokamaks during a plasma disruption. The formed vapor plasma (the boundary layer) absorbs a large fraction of the incident energy, and thus acts as a self protecting layer (vapor shield). Carbon materials (pyrolytic graphite and other graphite grades)) are used as plasma-facing components, and tungsten and refractory materials are potential candidates. The experimental test facility SIRENS has been used to expose carbon and tungsten materials to heat fluences between 0.2 and 6 MJ/m2 for 100 µs duration to characterize the performance of such materials under typical heat loading conditions.
