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 CIT design has evolved recently from a system in which the central solenoid outer boundary interacts with the inner legs of the toroidal field coils for mutual radial support during operation, to a system in which the central solenoid is radially self-supporting. The machine has also undergone some dimensional changes with a resulting increase in the demand for the total flux swing by the poloidal field (PF) coil system from 61 to 75 volt-seconds. This paper summarizes features of the two central solenoid designs and selected requirements for fabrication and operation. It also presents an update on results from the R&D program for this 20+ tesla coil system, together with future plans.
