Karen Koop Hogue - Safeguards and Security by Design @ ORNL MSRW 2023

Safeguards and Security by Design presented by Karen Koop Hogue at ORNL MSRW 2023. (Oak Ridge National Laboratory Molten-Salt Workshop 2023.)
Start by defining the objectives
• Define nuclear material control and accountancy objectives across a prospective liquid-fueled MSR facility, e.g.
Quantify nuclear material as it enters "difficult to access areas"
Detect nuclear material on used filters removed from off-gas system
• Identify which I felt was the most pressing R&D need
Nearest-term challenge
Gap in current technologies
Importance to safeguards and security
Conclusions
• Penetrating radiation can be a useful signature for both safeguards and security to quantify and monitor unirradiated fuel salt entering an MS
• Gamma and neutron detectors can be placed outside of insulation
Allows for typical detector materials to be used
• No detection system analyzed works for all potential MS designs, but HPGe detectors and passive total neutron counting work for most
• Design decisions impact feasibility of instrumentation
salt chemical composition, pipe diameter, pipe material, 235U enrichment
