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.

Several thousand tonnes of He-3 have been identified in various terrestrial reservoirs. The He-3 exists, however, as a dilute component, 10−9 to 10−12 volume fraction, of host gase such as the atmosphere or natural gas (methane). The production of He-3 is controlled, therefore, by the usage of the host gases. If the He-3 were separated from the host gases currently used, only 6 kg/yr would be obtained. With a vigorous expansion in the use of natural gas containing significant quantities of He-3, the production of He-3 could be increased to ∼ 25 kg/yr by the year 2000. This quantity of He-3 utilized in the d/He-3 fusion reaction would be sufficient to supply continuously several 100 MW fusion electrical power demonstration plants.
