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 advent of advanced and small reactor designs has led to the need for new, non-traditional fuels such as accident-tolerant fuel, fuel salts, and TRISO fuels, many of which will use HALEU. As such, new fuel cycle needs have arisen for fabricating, storing, and transporting these fuels. For example, molten salt reactors may require a centralized salt processing facility. Moreover, since used HALEU fuel still contains valuable HALEU, it may prove economical to recycle HALEU fuel. This panel session explores front- and back-end fuel cycle needs to enable successful deployment of small and advanced reactors.
