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.

A unique advanced design neutron absorber that provides significantly enhanced nuclear characteristics when compared with traditional designs has been developed for use in nuclear reactors. The design is a burnable absorber rod comprised of thin-walled Al2O3-B4C annular pellets contained within two concentric and sealed Zircaloy tubes so as to allow reactor coolant inside the center tube as well as outside the outer tube. A process was devised for fabrication of production quantities of the annular pellets that also satisfies special burnable absorber rod design constraints and performance requirements. This development has resulted in improved utilization of uranium resources and increased fuel management flexibiliy.
