Once-through nuclear reactor fuel compounds

摘要

The improved oxide, once-through plutonium fuel compound that can be used for nuclear fission in currently operating light-water reactors and fast reactors has a composition in the range defined by the lines that connect the three compositional points of a three-component system consisting of plutonium dioxide (PuO2), a plutonium host phase and alumina (Al2O3). The compound also has such a phase structure that two phases, the plutonium host phase having plutonium dioxide dissolved therein and the alumina phase, are in equilibrium.
