Date: Friday, May 9th
Presenter: Dr. Todd Allen, Deputy Director for Science and Technology, Idaho National Laboratory
Interfaces in a material are critical to performance in a nuclear system, including response to both radiation damage and corrosion. This presentation will overview three specific examples of critical materials interfaces: 1) The relationship between radiation-induced segregation and the growth of voids in irradiated steel, 2) The influence of grain boundary type on radiation-induced segregation, and 3) the effect of systems of grain boundaries on corrosion response in high-temperature water.
Dr. Todd Allen is currently the Deputy Director for Science and Technology at the Idaho National Laboratory, a position held since January 2013 while on leave from the University of Wisconsin. He has been a Professor in the Engineering Physics Department at the University of Wisconsin, since September 2003. In addition to my teaching and research responsibilities at Wisconsin, he was also the Scientific Director of the Advanced Test Reactor National Scientific User Facility, centered in Idaho Falls, Idaho at the Idaho National Laboratory and the Director of the Center for Material Science of Nuclear Fuel, a Department of Energy-sponsored Energy Frontier Research Center. Prior to joining the faculty at 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). Prior to graduate work, he was an officer in the United States Navy Nuclear Power Program.
