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 radiologically hostile environment resulting from the Three Mile Island Unit 2 accident required the application of various techniques to provide effective personnel contamination protection. A wide variety of protective clothing was utilized throughout the cleanup, ranging from cloth clothing to heavy-duty firefighter’s gear for work in areas containing highintensity beta contamination. In prescribing protective clothing, the overall risk to the worker was considered to ensure that the intended task could be performed at maximum efficiency. Through the application of appropriate protective clothing, skin contaminations were effectively minimized.
