Abstract

This report presents the results from characterization of zirconium and cerium doped uranium oxide pellets. The methods used were density measurements, high-resolution gamma spectrometry, X-ray diffraction (XRD), secondary electron microscopy for elemental analysis (SEM-EDX), optical emission spectrometry for dopant measurements (ICP-OES), mass spectrometry for elemental factor of uranium and for measurement of lanthanides.
