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.

One of the major safety concerns about pressurized heavy water reactors is the assurance requirement that the circular garter springs that surround pressure tubes remain at their specified locations. The eddy-current nondestructive method gives a timely warning when a significant displacement of garter springs occurs. The finite element method is used extensively to model eddy-current phenomena. Since a garter spring is an axisymmetric discontinuity, a two-dimensional finite element method is used to optimize eddy-current probe design parameters for the above application.
