In recent years, the International Atomic Energy Agency (IAEA) has pursued innovative techniques and an integrated suite of safeguards measures to address the verification challenges posed by advanced centrifuge technologies and the growth in separative work unit capacity at modern centrifuge enrichment plants. These measures would include permanently installed, unattended instruments capable...

Improvements to the current methods used by industry to identify uranium hexafluoride (UF6) cylinders would benefit International Atomic Energy Agency (IAEA) safeguards, inspectorates, and regulatory authorities, as well as facility operators. A move towards a standardized UF6 cylinder identifier is gaining momentum within industry. A National Nuclear Security Administration (NNSA) team has...

In this paper, the integration device of neutron and gamma ray was designed for measuring barreled uranium material which is the after-product in fuel element plant.
For barreled uranium with middle and low density matrix, the device used segment gamma ray scan technology and Monte Carlo imitation method to analysis the mass of uranium. For high density material, it added a neutron...

The common use Non-Destructive Assay techniques for the determination of 235U enrichment and mass of UF6 cylinders used in the production of nuclear reactor fuel require prior knowledge of the physical distribution of the UF6 within the cylinder. The measurement performance for these techniques is typically evaluated based on assumed bounding case distributions of the material. However, little...

Part of the scientific method requires all calculated and measured results to be accompanied by a description that meets user needs and provides an adequate statement of the confidence one can have in the results. The scientific art of generating quantitative uncertainty statements is closely related to the mathematical disciplines of applied statistics, sensitivity analysis, optimization,...
