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.

An empirical equation has been developed that predicts nitric-acid extraction from aqueous nitric-acid/sodium-nitrate solutions by tri-n-butyl phosphate (TBP) solutions. The predicted nitric-acid concentrations in the organic phase, for both 20 and 30 vol% TBP, are generally within ±0.02 M units of the experimental values when the total nitrate molarity in the aqueous phase is 1 to 7 M. The equation also predicts the extraction of nitric acid from nitric-acid solutions with reasonable accuracy.
