In Japan, it is important to identify nuclear forensics signatures that are conducive to identifying the origin and the history of various forms of reprocessed Pu. In this study, the identification of key signature nuclides was performed by machine learning method, dedicated to origin estimation of reprocessed Pu from the type of reactors (PWRs, BWRs, FRs), the type of fuel, and the separation and refinement ages.
