Information on the elemental and isotopic compositions of fuel debris is essential for the decommissioning of TEPCO's Fukushima Daiichi Nuclear Power Station. In this study, we have developed a double-resonance ionization scheme for highly sensitive and accurate isotope analysis of neodymium (Nd), which is a burnup indicator.
