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 deposition of iodine on low chromium-alloy steel (1% Cr—1/4% Mo alloy) has been investigated in vacuo at 316, 400, and 482°C using a pseudoisopiestic (static) method. An adsorption isotherm was obtained at 400°C over an iodine (monotomic) pressure range of 2.9 × 10-9 to 5.1 × 10-7 atm. The levels of iodine deposition at 400°C ranged from 3.8 to 23.2 µg I/cm2; these values are in agreement with data obtained using transpiration techniques. The low-level sorption data are interpreted on the basis of the dissociation of I2 to yield monatomic iodine as well as the interaction with the steel surface to form volatile iron iodides, which were deposited in cooler regions of the apparatus. The high-level sorption behavior of iodine on steel is in accord with the expected behavior based on the thermodynamic properties of FeI2(s).
