This thesis deals with the development of a new compact, accurate, fast, without cooling liquid, fluorescence L X-ray spectrometer, with the aim to determinate online transuranic elements (uranium, plutonium and americium) in nuclear materials reprocessing. The objective was to define the configuration and the characteristics of this spectrometer and the method to quantify transuranic elements between 0.1 g/L and 20 g/L. To minimize as law as possible the manipulation of these elements, we have used an original approach, namely Monte-Carlo simulations and none radioactive surrogate elements. The study of these solutions allowed to eliminate the specific effects of transuranic elements decay (internal conversion) and to optimize the spectrom...
