Field trials are an important instrument to test new safeguards equipment or methods if the new systems work in operational environment as foreseen. Circumstances can be much different in real facilities than laboratory surroundings. Also company policies (e.g. IT security) can give limitations to the implementation of new systems.
URENCO recognises its responsibility for international...

Verification of uranium hexafluoride (UF6) cylinders is one of the key components of enrichment plant safeguards, and in recent years, the International Atomic Energy Agency (IAEA) has explored the possibility of developing an Unattended Cylinder Verification Station (UCVS) to provide 100% verification of cylinders within an enrichment facility while reducing the need for routine measurements...

An on-line enrichment monitor was developed to measure the enrichment of UF6 flowing through the processing pipes in centrifuge uranium enrichment plant. A NaI(Tl) detector was used to measure the count rates of the 186 keV gamma ray emitted from 235U, and the total quantity of uranium was determined from thermodynamic characteristics of gaseous uranium hexafluoride. The results show that the...

The present work is a case study that describes a laboratory experimental method for estimating the U-235 mass content and/or enrichment in nuclear material bearing samples. A nondestructive assay technique has been developed for the verification of nuclear materials in cylinders. The technique is based on measuring the Gamma-rays counting rate emitted from a sample and calculating the...

Accurate verification of 235U enrichment and mass in UF6 storage cylinders and the UO2F2 holdup contained in the process equipment is needed to improve international safeguards and nuclear material accountancy at uranium enrichment plants. Small UF6 cylinders (1.5” and 5” diameter) are used to store the full range of enrichments from depleted to highly-enriched UF6. For independent...

The International Atomic Energy Agency’s (IAEA) long-term R&D plan calls for more cost-effective and efficient safeguard methods to detect and deter misuse of gaseous centrifuge enrichment plant (GCEPs). The IAEA’s current safeguards approaches at GCEPs are based on a combination of routine and random inspections that include environmental sampling (ES) and destructive assay (DA) sample...
