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.

A comparison of the key features of the D-3He Apollo and the DT Aries fusion power reactor designs is made. The reduction in neutron production from the D-3He reaction has a major effect on the performance of Tokamak reactors. One of the biggest impacts is the low radiation damage rate in D-3He systems which allows a permanent first wall to be utilized.. The reduction in radioactivity in D-3He reactors has a particularly advantageous effect on the storage of wastes as well as on the safety to the public in the event of the worst conceivable accident. The more difficult D-3He physics requirements are offset by the technological advantages of using this fuel in place of the DT cycle.
