TerraPower’s Natrium reactor advances on several fronts
TerraPower has continued making aggressive progress in several areas for its under-construction Natrium Reactor Demonstration Project since the beginning of the year. Natrium is an advanced 345-MWe reactor that has liquid sodium as a coolant, improved fuel utilization, enhanced safety features, and an integrated energy storage system, allowing for a brief power output boost to 500-MWe if needed for grid resiliency. The company broke ground for its first Natrium plant in 2024 near a retiring coal plant in Kemmerer, Wyo.

The effects of four common organic species (methanol, phenoxide, acetone, and methane) on the partitioning of iodine were studied over a range of concentrations, pHs, and radiation dose rates at ∼20°C. The primary goal of the study was to identify conditions leading to the production of significant quantities of volatile organic iodides. For all of the conditions studied, only the case of irradiated methane-iodine-air-water systems yielded sufficient volatile organic iodides to bring about decreases in the iodine partition coefficient.
