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 Payload Operations Integration Center is the 24/7 command post for research and technology activities on the International Space Station. The POIC manages all U.S. science, coordinates with international partners, and trains astronauts and ground team flight controllers.
The lab is the hub for advanced propulsion research and technology development. Highlights from its exhibit gallery include Marshall Space Flight Center's work on landers and the Rotating Detonation Rocket Engine. The Space Nuclear Propulsion Office will also have items displayed. Outside of the lab building is Propulsion Park, which includes a nuclear NERVA XE’’ engine, space shuttle solid rocket booster, aerospike engine, and F-1 engine.
NASA’s Marshall Space Flight Center is responsible for the design, construction, and testing of regenerative life support hardware for the International Space Station, known as the Environmental Control and Life Support System (ECLSS). Attendees will get to view modules that simulate the space station environment and examples of hardware that support the ECLSS.
The original test stand for the Redstone and Jupiter-C rockets. The site includes a blockhouse made of three rail tankers welded together and buried underground - this is where Wernher von Braun and his team observed and controlled engine test firings.
