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 recently completed Tokamak Fusion Core Experiment (TFCX) design project investigated potential “next generation” tokamak concepts. An important early development of the design was the incorporation of remote maintainability. Early coordination and incorporation of maintenance aspects to the design of the device and facilities will ensure that the machine can ultimately be maintained and repaired efficiently and cost effectively. A rigorously formatted engineering trade study was performed to determine the preferred configuration for the TFCX reactor based primarily on maintenance requirements. The study indicates a preferred design with an external vacuum vessel and torodial field coils that can be removed by simple radial motion. The trade study is presented and the preferred TFCX configuration is described.
