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.

One of the major safety concerns about pressurized heavy water reactors is the assurance requirement that the circular garter springs that surround pressure tubes remain at their specified locations. The eddy-current nondestructive method gives a timely warning when a significant displacement of garter springs occurs. The finite element method is used extensively to model eddy-current phenomena. Since a garter spring is an axisymmetric discontinuity, a two-dimensional finite element method is used to optimize eddy-current probe design parameters for the above application.
