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 National Environmental Policy Act requires Federal agencies to prepare environmental impact statements (EISs) for major Federal actions significantly affecting the quality of the human environment and provide opportunities for public participation to help inform agency decision making. For example, the NRC conducts an environmental review for proposed licensing, rulemaking and related regulatory actions. This panel will provide an overview of NEPA requirements, and recent updates to federal agency policies and associated guidance. The panel will include representatives from national labs, federal agencies, and industry to discuss ongoing initiatives for NEPA reviews related to nuclear licensing and decommissioning.
