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.

Accurate estimates of first-wall erosion in a compact fusion ignition experiment are important for the design of the first-wall system and its maintenance. Because of maintenance requirements and thermal response considerations, a smooth wall represents a good candidate for the first-wall. This type of wall is considered in an analysis of first-wall erosion in the IGNITEX high-field ignition tokamak. A poloidal model of the scrape-off layer is used with a new sputtering model to investigate the distribution of first-wall erosion and impurity penetration into the plasma. Estimates of erosion values at the wall during disruptions are calculated both with and without vapor. Vapor shielding effects are found to be significant. The effect of the thermal quench duration is analyzed and various low Z first wall materials are considered.
