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 Nuclear Safety Analysis Center (NSAC) at the Electric Power Research Institute has a Generic Safety Analysis Program to help resolve high-priority safety issues. Several high-priority safety issues considered at NSAC were resolved at least in part through the use of the RETRAN computer code. These issues are pressurized thermal shock, anticipated transients without scram in both pressurized and boiling water reactors, steam generator tube rupture, and scram frequency reduction.
