dc.description.abstractWithin natural UO2 fuel elements enriched with plutonium, this last material should form Pu02 solid solutions inside the UO2 pellets, in a wide range of concentrations. If the solutions are obtained by mechanical mixing o f the oxides, Pu02 islands are formed in the U02 matrix. These islands may be the source o f several problems in the fuel behavior, the most important being the overheating o f the matrix in the neighbourhood o f the particles. It is caused by the large fission cross section of plutonium compared with that of uranium.
