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.

Precise cross sections were measured for the 90Zr(n,)87mSr, 94Zr(n,)91Sr, 92Mo(n,)89m+gZr, 45Sc(n,)42K, 51V(n,)48Sc, 59Co(n,)56Mn, 93Nb(n,)90mY, 92Mo(n,p)92mNb, 96Mo(n,p)96Nb, 97Mo(n,p)97m+gNb, 90Zr(n,p)90mY, 91Zr(n,p)91mY, 92Zr(n,p)92Y, and 60Ni(n,p)60m+gCo reactions in the 7- to 14.7-MeV neutron energy range. Excitation functions were completed with a number of new differential data.Spectrum-averaged (n,) and (n,p) cross sections were measured for the 54Fe(n,)51Cr, 68Zn(n,)65Ni, 27Al(n,)24Na, 58Ni(n,p)58m+gCo, 64Zn(n,p)64Cu, 59Co(n,p)59Fe, 94Zr(n,p)94Y, 56Fe(n,p)56Mn, 46Ti(n,p)46m+gSc, 47Ti(n,p)47Sc, 48Ti(n,p)48Sc, and 62Ni(n,)59Fe reactions in addition to those aforementioned using a thick target Be(d,n) neutron field at Ed = 9.72 MeV. Results were compared with the ENDF/B-VI, IRDF90, JENDL-3, BROND, JEF-2, CENDL-2, and ADL-3 data files and the SINCROS-II system for testing the validation of differential data and the nuclear model calculations.
