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 effect of low-energy neutrons on activation cross-section measurements was analyzed carefully and proved by the measured neutron spectra of T(d,n)4He and D(d,n)3He reactions. The 58Ni(n,p)58m+gCo and 64Zn(n,p)64Cu reactions were used to confirm this analysis, and their cross sections were measured accurately. In addition, their evaluated excitation functions are given.
