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 simple method to measure the change in length of a silicon carbide temperature monitor due to annealing is presented. A differential dilatometer is used to detect the change in length of an irradiated specimen as the temperature of the specimen is raised in steps. The results obtained by this step-heating dilatometry method are in good agreement with measurements obtained with an X-ray diffractometer and a micrometer.
