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.

The hydraulic results of a series of 21-rod bundle water experiments have been analyzed systematically. Models are established for the prediction of the pressure drop over unblocked bundles, grid spacers, coplanar concentric blockage, coplanar concentric blockage with bypass, noncoplanar concentric blockage, and noncoplanar nonconcentric blockage. The models can be extended to other bundles with similar characteristics. The comparisons of these models with the experimental results agree reasonably well.
