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.

For the destruction of nitric acid in radioactive waste solutions from the reprocessing of nuclear fuel, a batch process has been developed using formic acid as a reducing agent. The main reaction products are N2O and CO2, which can be discharged into the environment. The process has been tested on a lab scale with simulated and real waste solutions as well as on a pilot scale with simulated solutions. Nitric acid turnovers between 80 and 90% are obtained. The final nitrate concentrations in high- and medium-level waste solutions are below 0.5 and 0.2 mol.ℓ−1, respectively. The induction period that occurs when starting the reaction can be described by a reaction rate equation. For our special conditions it lies within the range of a few seconds. The loss of solid particles and formic acid into the off-gas during the whole process amounts to a few parts per million. Corrosion tests under realistic conditions have shown that Incoloy 825 is an appropriate material for the denitration vessel.
