A Segmented Gamma Scanner for the Verification of LEU Oxide Powders
The verification of the amount of U oxide powder and the 235U/U abundance in typical fuel fabrication plant containers is described. Only gamma spectroscopy and direct calibration with standards are used. The measurements are performed scanning the container axis with a collimated detector. The spectrum energy considered covers the 1001 keV region to estimate the 238U mass and the 185.7 keV region to determine the 235U/U abundance. The gamma spectra taken at different axial positions of the container verify the homogeneity level of the sample.
