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.

Energy storage systems could be integrated with nuclear power plants to increase flexibility and potentially enhance revenues. This session will cover energy storage technologies that could couple to various coolant temperatures (medium- to high-temperature) or be integral to a plant's design. Energy storage classes include, but are not limited to, electrochemical batteries, mechanical compression/liquefaction of fluids, gravitational potential energy, heat storage materials (solids, liquids, gases; single- and multi-phase fluids), and power-to-X/synfuels.
