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 adjoint gamma transport theory method is used to analyze the postaccident gamma detector data from the Three Mile Island Unit 2 (TMI-2) reactor lower head. It is concluded that there are two layers of materials at position L-11 of the TMI-2 reactor lower head. The lower layer contains predominantly nonfuel materials and the upper layer contains predominantly fuel. It is also concluded that 137Cs, 137mBa, 60Co, and 154Eu have the highest contribution to the detector signal. Finally, it is shown that the detector field of view is very small; hence, further evidence is needed to generalize these results to the remainder of the TMI-2 lower head.
