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.

Tri-n-butyl phosphate (TBP) is an excellent industrial solvent for metal extraction in the nuclear chemical industry. It is also being used as a major constituent of hydraulic fluids in the aircraft industry and other industrial applications. Risk assessment studies demand limiting of airborne concentration of TBP during normal as well as accidental exposure to humans, as the toxicity index for TBP is quite high. Published data on TBP vapor pressure has been analyzed, and an empirical equation is reported for the temperature range of 273.15 to 562.15 K. The performance of the reported equation is compared with the correlations available in the literature.
