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.

This panel will discuss how the emerging compounds called PFAS/PFOS or "forever chemicals" have impacted the decommissioning of both nuclear plants as well as DOE facilities with respect to license termination. This panel will host Industry Subject Matter Experts (SMEs) to provide an overview of the chemical properties that lead to their wide used across industries and why they are in the focus of many community oversight committees and state/federal agencies. This panel will also host representatives from Nuclear Plants and DOE facilities to share their lessons learned with respect to the characterization and remediation of impacted media, and the challenges faced as state cleanup levels are being approved at values often far lower than EPA's Maximum Contaminant Limit (MCLS).
