Laser-induced breakdown spectroscopy for nuclear fuel material

Akaoka, Katsuaki ; Miyabe, Masabumi   ; Otobe, Haruyoshi  ; Wakaida, Ikuo  

For the remote analysis of the next generation nuclear fuel material containing minor actinide (MA), Laser Induced Breakdown Spectroscopy (LIBS) was applied to uranium oxide (U$$_{3}$$O$$_{8}$$) including a small amount of neodymium oxide (Nd$$_{2}$$O$$_{3}$$) as a simulated sample of MA. By using deconvolution technique for the spectra of Nd in U, the complex, overlapped and confused spectra were separated and their actual intensities were determined. As a result, the calibration curve with good linearity and the detection limit of less than 700 ppm were demonstrated.
