Preparation of simulated inert matrix fuel with different powders by dry milling method

Compressibility and sinterability of CeO2–8YSZ powders synthesized by a wet chemical method

“…As was described in Refs. [26,27], the ceramic for the inert matrix fuel must have a relatively low density (∼0.9 TD) and a well-formed microstructure and porosity.…”

Sol–gel synthesis and microwave assisted sintering of zirconia–ceria solid solution

“…The inert matrix fuel (IMF) consists of a solid solution of Pu in yttria-stabilized zirconia (YSZ) [4][5][6][7][8][9]. In IMF simulation studies, ceria is added as a surrogate for plutonia [10][11][12][13], since ceria and plutonia have similar physicochemical properties such as crystal structure, ionic size in octahedral and cubic coordination, standard enthalpies of formation, specific heats, melting points, etc. The synthesis of such oxide fuel is an art than science.…”

Ceramography Analysis of Mox Fuel Rods After an Irradiation Test

“…The peculiarity of the KAERI MOX fabrication processes is in the preparation process of the powder mixture, which uses the continuous type attrition mill [6] and the sintering of MOX compacts in a slightly oxidizing atmosphere [5]. The attrition mill consists of a vertical axis with impellers and two jars that are separated by an inconel grid into an upper and a lower part.…”
