Title: "Non-destructive Assay Nuclear Measurements at the Savannah River National Laboratory"

Abstract: Non-destructive assay (NDA) techniques are required to continue the efforts in monitoring and verifying safeguards for nuclear non-proliferation while ensuring the safe use of nuclear materials. This presentation will provide an overview of current technology used for NDA measurements, their key advantages, and challenges still faced in operation. In this discussion, both gamma-ray and neutron detection methods will be explained along with real world applications of NDA for nuclear material control and accountability (NMC&A) employed at SRNL. Lastly, current SRNL NDA efforts used in radiation contamination mitigation for the Savannah River Tritium Enterprise and hold-up measurements for the National Nuclear Security Administration Surplus Plutonium Disposition (SPD) program will be discussed.
