Abstract

Oxygen potential of a prototypic Mo-cermet fuel containing 50 vol.% PuO_2-x were investigated by the thermogravimetric analysis in the temperature range from 1273 K to 1473 K. It was shown that the oxygen potential and oxidation rate of the Mo-cermet were the same as those of pure PuO_2-x below the oxygen potential of Mo/MoO₂ oxidation reaction. The same features of the Mo-cermet sample containing 50 vol.% PuO_2-x with those of pure PuO_2-x were discussed in terms of the microstructure.
