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.

A special Chromel/Alumel thermocouple was fabricated whereby the bare ends of the wires were fixed ∼1 mm apart. In a medium with a good electrical conductivity (e.g., liquid sodium), the junction of this thermocouple is replaced by the medium itself. Hence, a fast undelayed response is expected. While mean temperature data of this device are in good agreement with data for conventional thermocouples, power spectral densities of the open element contain contributions from much higher frequencies than those of conventional thermocouples.
