Fine particles generated by fuel debris cutting have become a problem. We have been developing a spectroscopic analysis system in order to analyse the nuclides contained in it. Therefore, we designed and manufactured a sample introduction device and a plasma generation electrode for performing spectroscopic analysis on a sample introduced from the outside. In addition, we performed spectroscopic analysis of the sample introduced from the outside using a new sample introduction device. The results of these experiments are reported.
