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.
Advanced Reactor Safety (ARS) SPeaker
Ana has been working in nuclear safety for 39 years. From 1995 to 2000, she worked at the International Atomic Energy Agency (IAEA) where she was responsible for activities on probabilistic safety assessment, safety performance indicators and safety related maintenance for nuclear power plants.
Ana joined the UK Office for Nuclear Regulation in 2000 where she was Head of Advanced Nuclear Technologies (2016 – 2020) and Head of HPR1000 Regulation (2016 – 2022). She led the Generic Design Assessment (GDA) of the UK HPR1000 reactor, a large project that concluded in January 2022 with the issuing of a Design Acceptance Confirmation for the UK HPR1000.
In May 2022 Ana joined IAEA as Head of the Safety Assessment Section (SAS). SAS is one of the five sections within the Division of Nuclear Installation Safety (NSNI) in the IAEA Department of Nuclear Safety and Security. As Head of SAS Ana leads a team of 20 staff to deliver the needs of the IAEA Member States in the areas of ‘design safety’ and ‘safety assessment methods and tools’ covering existing, evolutionary and innovative reactors, including small modular reactors, non-water-cooled reactors, transportable nuclear power plants, and fusion facilities.
