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 radioactive tracer technique was used for directly measuring adsorbed material on surfaces typical in thermionic energy converters. Previously used techniques did not allow measurements to be made under the conditions expected in an operating diode. In these experiments, cesium tagged with radioactive 134Cs was adsorbed onto tantalum surfaces. Cesium arrival rates from 1016 to 1021 atom/(cm2 sec) and tantalum surface temperatures from 500 to 1700 K were investigated. The experimental curves were smooth and reproducible, establishing a high level of confidence in the technique.
