This technical note demonstrates the feasibility of using laser ablation inductively coupled plasma mass spectrometry for the characterization of Ue7Mo/Ale5Si dispersion fuel. Our measurements show 5.0% Relative Standard Deviation (RSD) for the reproducibility of measured 98Mo/238U ratios in fuel particles from spot analysis, and 3.4% RSD for 98Mo/238U ratios in a NIST-SRM 612 glass standard. Line scanning allows for the distinction of Ue7Mo fuel particles from the Ale5Si matrix. Each mass spectrum peak indicates the presence of U e7Mo fuel particles, and the time width of each peak corresponds to the size of that fuel particle. The size of the fuel particles is estimated from the time width of the mass spectrum peak for 98Mo by considering the scan rate used during the line scan. This preliminary application clearly demonstrates that laser ablation inductively coupled plasma mass spectrometry can directly identify isotope ratios and sizes of the fuel particles in UeMo/Al dispersion fuel. Once optimized further, this instrument will be a powerful tool for investigating irradiated dispersion fuels in terms of fission product distributions in fuel matrices, and the changes in fuel particle size or shape after irradiation.
