るためには非常に高い分解能の分光器を必要とする．こ の様な複雑に混在する 含有燃料を模擬するために， アクチノイドと同様に最外殻の s 軌道電子が占有され閉 能の分光器を用いてスペクトルの測定を行い，解析では 定量性を高めるために測定されたスペクトルをデコンボ For the remote analysis of a next generation nuclear fuel material containing minor actinide (MA), we applied laser-induced breakdown spectroscopy (LIBS) to uranium oxide (U 3 O 8 ), which included a small amount of neodymium oxide (Nd 2 O 3 ), as a simulated sample of MA. By using a deconvolution technique for the Nd spectra in U, we separated the complex, overlapped, and confused spectra and determined their actual intensities. As a result, a calibration curve with good linearity and a detection limit of less than 700 ppm were demonstrated.
