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.

Hastelloy X electron beam (EB) weld metal shows higher creep rate and slightly lower rupture strength, and the tungsten inert gas (TIG) weld metal shows remarkably lower creep rate and rupture strength as compared with the base metal. Creep behavior for welded joint is determined mainly by the relation between the welding direction and the loading one, the creep rupture times, and the secondary creep rates of base and weld metal. In applying TIG and EB welding to joints of the shell or tubes, there are few problems for EB welding, but for TIG welding it is necessary to improve the weld metal.
