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 program was carried out to develop a sodium vapor pressure measuring system using beta-alumina ceramics for use in developing sodium vapor traps and monitoring sodium mist in cover gas for fast breeder reactors (FBRs) and test facilities. The sensor device was tested in a vacuum glass capsule. Its output agreed well with theoretical results. Moreover, it proved to have the capability of measuring a lower vapor pressure near 10−5 Torr without any calibrations. The measuring system, consisting of a beta-alumina sensor device, gas circulating pump, gas heater, and mist trap, is applicable to FBR plants and test facilities that contain much sodium mist and to a transient monitoring system. This system was tested in an isothermal sodium vapor circulation test loop under conditions involving much sodium mist.
