Abstract :
In this paper, we report our progress toward the development of an advanced enrichment monitoring technology for safeguarding gas centrifuge enrichment plants. We compare the UF6 gas pipe attenuation and sensitivity to X-ray tube HV variations for two transmission energies: 22 keV and 25.5 keV. The first experimental enrichment results taken with a static UF6 gaseous source and X-ray tube based transmission source over a wide gas pressure range are presented.
