Past studies have shown that actinide waste discharged from light water reactors (LWRs) could be burned effectively in liquid-metal fast reactor systems. These systems were predominantly mixed plutonium/uranium oxide or metal breeder systems with small percentages of minor actinides. This study illustrates how LWR actinides and fission products could be burned in a minor actinide nitride-fueled advanced liquid-metal reactor (ALMR) that has special moderating assemblies to enhance fission product transmutation. For this study, the reactor was assumed to be only a burner, not a breeder. The model contained a preponderance of minor actinides with only sufficient plutonium to maintain 1-yr fuel cycles. No uranium was loaded because plutonium production was not desired.
