Presentation: ETI: Signature Discovery within Additive Manufacturing

Venue: Rio Cantina, 1049 Center Street (at SRP Park and across from the Crowne Plaza hotel), North Augusta, SC 29841

Time/Date: 6:00 PM, Thursday, February 15, 2024. Program begins approximately at 7:00 PM.

Abstract:

The Consortium for Enabling Technologies & Innovation (ETI) is sponsored by NNSA and includes fourteen universities and twelve national laboratories (SRNL is a partner in ETI). ETI has three thrusts: 1) data science and autonomous solutions, 2) advanced manufacturing for nonproliferation, and 3) novel instrumentation and sensors. This presentation will focus on projects that cut across all three thrust areas to identify signatures from additive manufacturing. Advances in manufacturing technology enable the production of complicated physical objects with less effort and skill than traditional manufacturing. From a nuclear nonproliferation perspective, there is a concern that a proliferator could bypass export controls through the utilization of advanced manufacturing. Side-channel data including acoustic, vibration, and current data have been collected from manufacturing runs. Machine learning algorithms are utilized to extract signatures that identify manufacturing methods and objects that are being manufactured.

Biosketch:

Dr. Steven Biegalski is the Chair of Nuclear and Radiological Engineering and Medical Physics at Georgia Institute of Technology. Early in his career Dr. Biegalski was the Director of Radionuclide Operations at the Center for Monitoring Research. In this position Dr. Biegalski led international efforts to develop and implement radionuclide effluent monitoring technologies. This work supported both U.S. national capabilities and international treaties.

Prior to joining Georgia Tech, Dr. Biegalski was a faculty member at The University of Texas at Austin for 15 years and held the position of Reactor Director for The University of Texas at Austin TRIGA reactor for over a decade. He has published over 200 peer-reviewed articles, three book chapters, and has advised 28 Ph.D. students for award of their degrees. He is currently the Thrust 2 Advanced Manufacturing for Nonproliferation lead for ETI.
