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.
Conference on Nuclear Training and Education: A Biennial International Forum (CONTE 2025)
Dr. Todd Allen is Professor at the University of Michigan and a Senior Fellow at Third Way, a DC base Think Tank, supporting their Climate & Energy Portfolio. He is the Founding Director of the Fastest Path to Zero Initiative, aimed at identifying the combined technologies and social acceptance that moves towards decarbonized systems. He is also the Co-Director of the University of Michigan’s hydrogen initiative, MI Hydrogen.
He was the Deputy Director for Science and Technology at the Idaho National Laboratory from January 2013 through January 2016. Prior to INL he was a Professor in the Engineering Physics Department at the University of Wisconsin, a position held from September 2003 through December 2012 and again from January 2016-December 2018. From March 2008-December 2012, he was concurrently the Scientific Director of the Advanced Test Reactor National Scientific User Facility at INL. Prior to joining the University of Wisconsin, he was a Nuclear Engineer at Argonne National Laboratory-West in Idaho Falls.
His Doctoral Degree is in Nuclear Engineering from the University of Michigan (1997) and his Bachelor’s Degree in Nuclear Engineering is from Northwestern University (1984). Prior to graduate work, he was an officer in the United States Navy Nuclear Power Program.
