Dr. Stefan Anton is senior vice president of Engineering and Licensing for Holtec International. In this role, he provides management and leadership of complex technical programs including first-of-a-kind projects for the domestic and international nuclear market. Dr. Anton oversees all dry storage criticality and shielding evaluations performed at Holtec. Under his leadership, Holtec’s engineers developed wet storage racks for many operating nuclear power plants, and completed the design and licensing process of numerous dry storage and transport systems. This includes the methodology to bound a wide array of fuel types and site conditions for the general licenses granted under U.S. 10 CFR 72 and 10 CFR 71, and the methodology for burnup credit for spent fuel racks and spent fuel storage and transport systems.

Professional History

Dr. Anton has more than 30 years of experience in the design and licensing of structures, systems and components for the nuclear energy industry. Prior to his current appointment at Holtec, he has held several notable positions, including senior/principal engineer, licensing manager, director of Technical Services and Licensing and vice president of Engineering and Licensing.

Prior to moving up the ranks at Holtec, Dr. Anton worked as senior engineer at WTI GmbH located in West Germany and in that role, he was member of the design team that developed the CASTOR spent fuel storage and transport cask system.
