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.

An electrochemical carbon meter using liquid Na2CO3-Li2CO3 eutectic contained in a thin-walled iron membrane cup was constructed. A reference electrode was kept immersed in the electrolyte. The membrane cup assembly was dipped into static sodium for analysis. Carbon in sodium equilibrates with the iron membrane. An electromotive force was developed across the electrolyte due to the presence of a carbon activity difference and this was measured using a high impedance digital volt meter. The measured electromotive force was dependent on the type of reference electrode used in the probe. Further characterization of the reference electrodes is needed for the reliable operation of this type of carbon meter for sodium. However, graphite seems to fit best the requirements of materials for use as the reference electrode.
