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.

A KrF excimer laser system is experimentally used to photochemically induce the reduction of 1 × 10−4 mol/dm3 Np(VI) to Np(V) while in a solution of 30% tri-n-butyl phosphate (TBP) and nitric acid. It is found that Np(VI), initially prepared from KMnO4 and then extracted by 30% TBP, can be reduced by the reaction with nitrous acid, which is produced by photolysis of nitric acid. The experimental results have demonstrated that laser-induced redox reactions are effective in changing the distribution ratio and reaching equilibrium quickly.
