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 236U(n,f) cross section has been measured in the energy range from 0.5 eV to 25 keV at the Geel Electron Linear Accelerator neutron time-of-flight facility of the Institute for Reference Materials and Measurements in Geel, Belgium. A highly enriched 236U sample was mounted back-to-back with a 10B sample in the center of a Frisch-gridded ionization chamber, hence realizing a 2 detection geometry. A 235U(n,f) cross-section control measurement was performed in the same experimental conditions. Special attention has been given to the fission resonance integral If and to the strongest resonance at 5.45 eV, for which a resonance analysis has been performed yielding f = 1.7 eV. Both values are highly overestimated in the literature.
