TerraPower has taken a critical step toward international deployment of its Natrium® reactor by initiating the United Kingdom’s Generic Design Assessment (GDA) process. The move signals strategic intent to enter a global market increasingly focused on decarbonization, grid stability, and energy security. The GDA, overseen by UK nuclear regulators, will assess the safety and viability of the sodium-cooled fast reactor and its integrated molten salt-based energy storage system.
This advancement comes as TerraPower’s U.S. project in Wyoming proceeds through regulatory milestones, including early federal and state construction approvals. The company’s domestic progress may serve as a model for UK regulators looking to accelerate timelines for advanced nuclear technologies.
