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.

Calculations for the excitation functions of the 58Ni(n, )55Fe reaction, including those of the ground and first states of 55Fe, 58Ni(n, p+p)54Mn, 58Ni(n,2n)57Ni, 58Ni(n,n')58Ni, and 58Ni(n,np+pn)57Co reactions were carried out using nuclear reaction model codes. The results have been compared with reported measurements and evaluations. The available data on the 58Ni(n,n')58Ni, 58Ni(n,2n)57Ni, and 58Ni(n,np+pn+d)57Co reactions are described well by using the single-particle model for the calculation of gamma-ray transition probabilities of the excited states of 58Ni.
