The International Atomic Energy Agency (IAEA) has established international safeguards standards for fissionable material at spent nuclear fuel reprocessing plants to ensure that significant quantities of weapons-grade nuclear material are not diverted from these facilities. Currently, methods to verify material control and accountancy (MC&A) at these facilities require time-consuming and...

At the ponds of La Hague (F) different types of material are stored awaiting reprocessing:
• Irradiated LEU fuel assemblies,
• Fresh MOX scrap of different origins,
• Irradiated MOX assemblies from research reactors,
• Irradiated L/HEU assemblies from research reactors.
According to the safeguard approach developed by Euratom, irradiated LEU fuel is verified by Cerenkov...

UV-VIS-NIR Spectroscopy is a simple and inexpensive measurement technology which has been proposed for process monitoring applications at reprocessing plants. The purpose of this work was to examine if spectroscopy could replace more costly analytical measurements to reduce the safeguards burden to the operator or inspector. Recognizing that the higher measurement uncertainty of spectroscopy...

A Reference Engineering-scale Pyroprocessing Facility (REPF) concept was developed through a Member State Support Program (MSSP) for the “Support for Development of a Safeguards Approach for a Pyroprocessing Plant”. Homogenization process, which was aimed to make the homogenous powder for the nuclear material accountancy, was included in the head end process. Material Balance Area (MBA)s and...

Microfluidic techniques enable production of micro-samples of molten salt for analysis by at-line and off-line sensors and detectors. These sampling systems are intended for implementation in an electrochemical used fuel treatment facility as part of the material balance and control system. Microfluidics may reduce random statistical error associated with sampling inhomogeneity because a large...
