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 National Aeronautics and Space Administration (NASA) Radioisotope Power Systems (RPS) Program Mission Analysis Team at the Jet Propulsion Laboratory (JPL) requested a JPL Innovation Foundry Architecture Team (A-Team) study to assess mission pull for small RPS [1 to 40 W(electric)] and define the focus of future power system developments required to enable small RPS missions. The A-Team is JPL’s concurrent engineering design team for science definition and early mission concept development, targeting concept maturation levels of 1, 2, and 3. The requested small RPS study aimed to identify the architecture space of potential small RPS missions and suggest power levels that could enable or enhance potential future small spacecraft missions.
This technical note describes the collaborative engineering processes that the A-Team and Mission Analysis Team used to reach results quickly and presents the findings on power requirements for small RPS mission concepts.
