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 paper presents a novel universal concept of recovering tritium from water. The concept is based on a flexible link between the first stage of purification and getting tritium concentrate by catalytic isotopic exchange between water and hydrogen and the second stage, destined for recovering tritium with the concentration of 98 at.% by means of continuous isotopic exchange between hydrogen and palladium hydride. We present thermodynamic and mass exchange parameters of these processes, obtained while running pilot setups. We demonstrate that the proposed universal purification module is more efficient for separating tritium-containing mixtures of hydrogen isotopes, than the one described in literature.
