摘要: AbstractFor the burning of plutonium derived from nuclear warheads, once-through type oxide fuels have been studied by considering their proliferation resistance and environmental safety as well technological backgrounds fuel fabrication reactors.From phase relations ceramic materials chemical properties, it seems that a two-phase mixture fluorite-type alumina has favorable characteristics once-through-type burning. It also phases such thoria fully stabilized zirconia are acceptable host because high solid solubility actinide elements fission products, irradiation stability, stability. The spent finally obtained will become mineral-like waste forms, which could be buried under deep geological formations without further processing.From reactor burnup calculations with use fuels, light water reactors (LWRs) larger volume ratio m...
