Identification of unknown spent nuclear fuel with factor analysis for nuclear forensic purpose

Precise and accurate isotopic analysis of uranium and thorium in uranium ore concentrates using ICP-MS and their age dating for nuclear forensic analysis

“…Multivariate and pattern recognition techniques are of great interest in data analysis and database building for nuclear forensic purpose. 7,32 Here we showed 235 U/ 238 U, 234 U/ 238 U and 230 Th/ 234 U in 3D space, where every sample is obviously unique from others. The visualization of the data proved that the application of multiple isotopic systems or signatures will be helpful to discriminate the possible sources and have valuable potential in this endeavor (Fig.…”
