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 session will highlight current and emergent issues in consensus standards, with a focus on industry needs for standards actions. The topics will also include: moving from risk informed to performance based standards; harmonization among ANS standards and between ANS standards and standards from other SDOs; digital twins as an adjunct to licensing by test; potential for standards action for System-Theoretic Process Analysis; perspectives by several ANS Consensus Committees; and may include perspectives from ASME, EPRI, IEEE, INPO, NEI, ISO and regulators. The Risk-Informed, Performance-Based Principles and Policy Committee (RP3C) has participated in organizing this panel.
