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.

Improved methods for storing liquid hydrogen in larger quantities and over longer periods of time in space are becoming progressively more critical as sights are once again set on Mars. Current storage methods involve the venting of vaporized hydrogen to space, with the consequence that significant amounts of hydrogen are wasted. Extra hydrogen must be stored to account for this loss resulting in unnecessary mass penalties. Eliminating this waste can reduce overall mission mass, extend mission range, and perhaps most importantly, lower mission trip times and costs. This technical note explores alternative methods for storing liquid hydrogen with an emphasis on missions to Mars as laid out by the National Aeronautics and Space Administration’s current design reference architecture.
