摘要: AbstractA nuclear forensics methodology has been developed that is capable of source attribution separated weapons-grade plutonium in case an interdiction. The utilizes and contaminant fission product isotopes within the sample to determine characteristics (reactor parameters) interdicted material. reactor parameters interest include type, fuel irradiation burnup, time since irradiation. MCNPX-2.7 radiation transport code was used model cores perform neutronics simulations estimate resulting irradiated UO2 fuel. simulation results were create a reactor-dependent library isotope ratio values as function burnup Ratios intra-element (fission or actinide) are combination could have produced sample. isotop...
