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 instrument has been developed to continuously measure the steam content in flowing steam/air mixtures. This instrument is nonintrusive and thus can be used in existing and proposed future experimental facilities in such a way as to not affect the flow field. The instrument detects the steam content by measuring the differential attenuation of infrared radiation passing through the flowing fluid. A small steam/air test facility has been designed and constructed and was used to calibrate this instrument. Experiments have indicated an instrument accuracy of ±5% in the measurement of steam/air fraction. This is particularly impressive considering the small (1.9-cm) steam/air attenuation path utilized.
