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 response of liquid metal self-cooled fusion reactors to a loss of flow accident (LOFA) has been investigated. Coolant temperature rise through the blanket was determined for conditions where decay heat is removed solely by natural convection. It was found that lithium-lead (Li17-Pb83) coolant provides sufficient natural convection to remove decay heat in both tokamak and TMR designs with a reasonable temperature rise. With pure lithium coolant, however, decay heat removal by natural convection proves difficult without excessive temperature rise. A transient analysis reveals that there should be ample time to respond to a LOFA if the plasma is shut down promptly.
