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.

Rapid nondestructive mineral analysis can be performed with use of a 252Cf neutron source and a lithium-drifted germanium [Ge(Li)] diode gammaray detector. Also, in situ analysis of terrestrial and marine mineral deposits appears practical. Laboratory studies show that a 1- or 2-min exposure of mineral samples to the thermalized neutron flux from a 1-mg 252Cf source followed by a 1- or 2-min count with an 80-cm3 Ge(Li) diode will allow the measurement of most elements at concentrations of 10- to 100-fold below the levels of economic interest. The technology developed for laboratory mineral analysis is described and its applicability to in situ terrestrial and seabed mineral exploration is discussed.
