Novel Detection Technologies for Safeguards and Security Applications

Novel detection technologies designed specifically for safeguards and security applications can provide breakthrough solutions for critical nuclear problems.  NSSPI researchers have identified interesting new detection approaches which may offer significant performance improvements for certain applications in the safeguards and security arena.  Preliminary investigations have shown that acoustic dissipation may be useful for detecting the presence and character of high-density materials (shielding and/or SNM).  In addition, properly characterizing detection thresholds between background radiation and heavily-shielded sources could yield a cost-effective detection system targeting smuggled HEU and plutonium.  This project will support computational and laboratory experiments to confirm the potential of these novel technologies for detecting and measuring special nuclear material, radioactive sources, and/or their related shielding materials.
