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.

The dynamic measurement of the reaction in T2-CO 1:1 mixed gas was carried out using laser Raman spectroscopy. A catastrophic change was observed in the Raman spectra due to appearance of fine particles floating in the quartz Raman cell at about 100 min after mixing. Assignment of the new peaks on the spectra due to appearance of the particles was not successful. An attempt to specify the solid reaction product by mass spectroscopic analysis of the gas phase constituent showed the elemental formula of the product was about C1.4: T3.0: O1.0.
