It is expected that the important data for design of fast reactor fuel can be provided by evaluating the relationship between fuel composition and phase separation with reported and new measurement data. According to evaluation with reported data and new measured data, a relationship between fuel composition and phase separation temperature of MOX fuel was indicated. Higher minor actinides-containing MOX had a lower phase separation temperature at O/M ratio region from 1.92 to 1.96.

Sintering behavior of MOX pellets prepared by mechanical blending method

no journal, , 

Sintering behavior of MOX pellets prepared by the mechanical blending method was evaluated from measurement results of the O/M ratio and dimensional shrinkage of the pellets during sintering. Change of the O/M ratio occurred when approaching the equilibrium condition which was decided from oxygen potential depending on the P$$_H$$$$_2$$/P$$_H$$$$_2$$$$_O$$ ratio in the sintering atmosphere. The O/M ratio increased and the MOX pellets shrank at lower temperatures with decreasing P$$_H$$$$_2$$/P$$_H$$$$_2$$$$_O$$ ratio. The MOX pellets sintered near O/M = 2.0 showed more homogeneous distribution of uranium and plutonium than those of other specimens.
