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 detailed evaluation of the electromechanical force distributions in the vacuum vessel of the IGNITEX device during major plasma disruptions is presented. The effects of the disruption plasma conditions, the single-turn toroidal magnet system, and the vessel resistivity are discussed. The electromechanical stresses are evaluated and stress distributions are presented. It is shown that the electromechanical forces due to plasma paramagnatism are comparable to the usual forces due to the plasma toroidal current. The stress analysis is performed for the proposed IGNITEX vacuum vessel.
