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.
Radiation Protection and Shielding Division 2024 (RPSD 2024)
Sean Fournier is a nuclear engineer in the Sandia National Laboratories Nuclear Incident Response Program (NIRP). He received his MS in Nuclear Engineering from the University of New Mexico in 2018. Sean started his career in 2010 working in the radiochemistry laboratory at Sandia. Sean has participated in several inter-agency working groups on nuclear incident response preparedness; most notably, the Department of Energy’s Federal Radiological Monitoring and Assessment Center (FRMAC) Laboratory Analysis Working Group. This group is responsible for determining the methods, procedures, and training for sample control and analysis during a national-scale nuclear emergency. Sean is the current skillset leader for the Consequence Management Laboratory Analysis Unit and works toward maintaining readiness of the responders and the technology used by the team.
