Inductively Coupled Plasma Mass Spectrometry (ICP-MS/MS) is expected as a method for efficiently and accurately analyzing fuel debris extracted from the Fukushima Daiichi Nuclear Power Station. The purpose of this study is to investigate the stability (leaching characteristics) of fuel debris in the process from storage to disposal by conducting microchannel running water tests using simulated fuel debris. This report outlines the experimental results using (U, Zr, Ca)O_x as simulated fuel debris.
