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.

Implementing the NEPA Amendments Enacted by the Fiscal Responsibility Act: Improving Efficiency While Balancing Public Involvement Opportunities in Environmental Reviews The Fiscal Responsibility Act of 2023 (FRA) amended the National Environmental Policy Act (NEPA). Prior to the FRA, NEPA had been largely untouched since it was signed into law in 1970. NEPA requires Federal agencies to prepare environmental impact statements (EISs) for major Federal actions significantly affecting the quality of the human environment and provides opportunities for public participation to help inform agency decision making. This panel will review the changes made to NEPA by the FRA, and how federal agencies are updating their policies, regulations, and associated guidance. The panel will include representatives from federal agencies and environmental contractors to discuss ongoing streamlining and modernization of environmental reviews in response to the NEPA amendments, section 506 of the ADVANCE Act, and CEQ regulation revisions.
