Development of direct elemental analysis for process control of nuclear materials manufacturing

2019

In order to optimize the quality control processes of uranium and plutonium metals from nuclear industry production lines, laser-induced breakdown spectroscopy (LIBS) appears as an efficient technique: it enables multi-element, fast and remote chemical analysis that require no sample preparation. Thus, the purpose of our work is to develop this technique towards the quantification of metal impurities in nuclear materials, with an analytical development achieved from surrogate materials. It follows another PhD thesis where a particular spectral band, Vacuum UltraViolet, has been chosen for its performance regarding the detection of several light elements in such materials. However, after per…
