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 complete sets of nuclear data for n + 92,94,96Mo below 20 MeV are calculated. These sets include all kinds of cross sections, especially for some reactions from the residual nuclei in metastable/isomeric states, angular distributions of elastic scattering, energy spectra and/or double-differential cross sections of all emitted particles, and gamma production data (production cross sections and multiplicity, energy spectra) in all kinds of reactions. The calculated results are generally in good accordance with the experimental values for those reactions with the experimental data. In the final evaluation files, most data are directly taken from the calculated values; only a few of them are changed based on the experimental data and are referred to JENDL3.2.
