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.

Although chemical sprays are effective for removing radioactive iodine, the suitability of a particular chemical solution for use in the reactor building spray system depends upon the solution’s stability and compatibility in the environment produced by LOCA. The suitability of alkaline sodium thiosulfate for use in the reactor building spray system as an iodine-removal agent has been the subject of an extensive research and development program by Babcock & Wilcox. The results of the program demonstrate the stability and compatibility of the sodium-thiosulfate spray solution.
