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 grain boundary of Armco Iron in liquid lithium, under the influence of steady-state creep, was investigated and showed a parabolic time dependence. An observed delay time for the grain boundary attack was correlated with the nucleation of a grain boundary corrosion product. The activation energies for creep and grain boundary penetration kinetics were found to be the same. Grain boundary penetration behavior under the influence of compressional stresses is the same as under the influence of tensile stresses, suggesting that plastic deformation controls the penetration kinetics regardless of the stress state that causes the plastic deformation.
