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.

Compositional changes in the surface region of single-crystal SiC(0001) due to heat treatment and light ion irradiation in the keV range were studied with the use of AES. The heat treatment at 1000°C formed a carbon enriched layer with a thickness of 20 Å on the top surface and a carbon depletion layer below this layer. Both hydrogen and helium ion irradiation caused depletion of silicon atoms in the near surface region and depletion of carbon atoms in the deeper surface region. TRIM computations revealed that in the process of slowing down of incident hydrogen ions, their kinetic energy was transfered preferentially to silicon atoms in the near surface region and to carbon atoms in the deeper surface region. This tendency explains the formation of each altered layer.
