摘要: Abstract This study uses a precipitation method to synthesize zirconia–magnesia inert matrix fuel containing plutonium oxide as the fissile material and erbium burnable poison. X-ray diffraction, secondary electron microscopy with energy dispersive spectroscopy, optical microscopy, probe microanalysis were used determine phases present, phase mixing, microstructure, stoichiometry, elemental distributions throughout samples. A large range of magnesium zirconium oxides well different concentrations was studied. It found that it possible two consisting pure MgO (periclase) cubic zirconia which incorporated all small amount oxides. information will be understand dissolution behavior properties this in conditions relevant an advanced nuclear cycle.
