Evaluation of compositional micro-homogeneity in MOX fuels using lab based μ-XRF spectrometry

Abstract

A highly sensitive and simple Micro-X Ray Fluorescence (µ-XRF) based methodology has been developed for the direct non-destructive compositional analysis and micro-homogeneity studies of Mixed Oxide (MOX) fuel pellets of...

2023 atomic spectrometry update – a review of advances in X-ray fluorescence spectrometry and its special applications

“…Homogeneity is an important parameter monitored in the QC of fabricated MOX fuel pellets . Sanyal et al 25 analysed MOX fuel pellets, prepared by three fabrication routes, to provide size and concentration data for uranium agglomerates. The concentration of U (2–50%) could be determined with a high precision of <1%.…”

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Sanyal et al used micro-focused XRF to assess the homogeneity of U and Th fuel pellets prepared via different routes. 178 The technique was capable of mapping U in each spot on the fuel pellet with concentrations of 2-50% with respect to Th. The instrument's small footprint enabled the installation in a glovebox that would allow Pu pellet measurement.…”
