Ceramic nuclear fuels in the system ZrO₂ - CaO - UO₂
Potential nuclear fuels in the system ZrO2-CaO-UO2 were investigated. Cubic fluorite-type solid solutions, as indicated by x-ray diffraction patterns, were formed by sintering CaO-stabilized ZrO2 and U3O8 compacts in either air or H2. A continuous solid solution was found between urania and stabilized zirconia with H2 sintering at 1750 deg C. Air sintering produced a limited region of solid solution in the stabilized zirconia portion of the system at 1450 deg C. Results on phase identification, oxidation behavior, and water corrosion are presented.
