Description

(U, Pu)O2 mixed oxide fuels with different percent of plutonium have been developed and used all over the world in commercial and research reactors. (U0.72Pu0.28)O2.00 is used as a nuclear fuel in Prototype Fast Breeder Reactor (PFBR) at Kalpakkam. CeO2 has been used as a surrogate for PuO2 because of similarity in their thermophysical and thermochemical properties. In addition, cerium is one of the high yield fission products formed during burn up and dissolves in UO2 matrix to form (U, Ce)O2. It is reported that the oxidation and phase behavior of (U1-yCey)O2±x system are quite comparable to (U1-yPuy)O2±x system in hyper-stoichiometric (2+x) region than in hypo-stoichiometric (2-x) region. (U0.72Ce0.28)O2 was prepared by gel combustion route followed by sintering at 1400°C for 10 h in Ar/8%H2 atmosphere
