Nuclear forensics is the analysis of intercepted illicit nuclear or radioactive material and any associated material to provide evidence for nuclear attribution by determining origin, history, transit routes and purpose involving such material. Because the nuclear forensics methodologies provide hints of the origin of the nuclear materials used in illegal dealings or nuclear terrorism, it contributes to identify and indict offenders, hence to enhance deterrent effect against such terrorism. In the 59th Symposium on Radiochemistry, the results of research and development of fundamental nuclear forensics technologies (analysis of isotopic composition, impurity analysis, age dating of nuclear material, particle shape analysis by electron microscope, and nuclear forensics library) performed in Japan Atomic Energy Agency are reported. Japan's capability and the role of radiochemistry on nuclear forensics are also discussed in the Symposium.

The analytical procedure to separate from the impurity metals was established by adsorption of Pu and Am using TRU resin to analyze the impurity metal in Pu nitrate solution recovered from spent nuclear fuel.

Japan Atomic Energy Agency's Plutonium Fuel Development Center is considering introducing ICP-AES as a new method for analyzing the metal impurity content in MOX samples. The emission spectra of Pu and U, the main components of MOX samples, are extremely complex, resulting in continuous background increases and spectral interferences. Therefore, in order to accurately quantify the metal impurity elements in the MOX sample, it is necessary to remove Pu and U as a pretreatment for analysis. In this presentation, we will report on the outline and results of experiments related to this pretreatment.
