Abstract
The verification of the amount of U oxide powder and the 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 1,001 keV region to estimate the 235U/U 238 abundance. The gamma spectra taken at different axial positions of the container verify the homogeneity level of the sample. U mass and the 185.7 keV region to determine the 235U/U
