dc.descriptionUranium dioxide has been the most common ceramic fuel used to generate electric power in the last sixty years. The lower addition of chromic oxide (Cr2O3) shows the benefits of large grain size. Using (Cr2O3-Al2O3)-doped UO2 comprises improved mechanical response and fission gas retention properties. The addition of Cr2O3 to UO2 slightly affected its thermal properties as proposed for pressurized water reactors and boiling water reactor designs. Advanced doped pellet technology (ADOPT) can improve fuel cycle economics and accident tolerance. Today, doped fuel pellets exhibit several favorable characteristics: large grain size, increased density, minor fission gas release (FGR), and reduced pellet cladding interactions. In simulation are used FRAPCON to simulate doped fuel and ferritic alloy as cladding. Most of the material properties of the Cr2O3-doped UO2 were identical to those of the classic UO2.
