Abstract
A hot cell-based solid sampling system has been developed for application to the analyses of irradiated materials such as metallic reactor fuel from a nuclear reactor, and radioactive waste forms. This system employs one of two sampling techniques, glow discharge or laser ablation, for introduction of material into one of two instruments for analysis, either a time of flight mass spectrometer or an inductively coupled argon plasma-atomic emission spectrometer (ICP-AES). This paper will discuss using ICP-AES for the analysis of major, minor and trace constituents in an unirradiated U-10 wt % Zr metallic reactor fuel. The behavior of highly refractory elements, such as Zr, in the laser ablation process will be examined in detail. Additional corroborative data provided via scanning electron microscopy-energy dispersive x-ray fluorescence spectroscopy (SEM-EDS) will be presented.
