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.

In conjunction with the small-scale, melt/concrete interaction tests being conducted at Sandia Laboratories, an acoustic technique has been used to monitor the penetration of a molten, metallic pool into concrete. Real-time plots of the position of the melt/concrete interface have been obtained, and they illustrate that the initial penetration rate of the melt may be on the order of 80 mm/min. Phenomena deduced by the technique include a nonwetted melt/concrete interface.
