The HDR series is constituted of dissertations written by the IRSN's researchers to obtain the Authorization to Direct Research or HDR. This diploma granted in the sciences by French universities is the most advanced degree and allows to apply to University Professor position. This HDR dissertation presents an overall picture of scientific results obtained after several years of research and draw the guidelines of the future scientific project of the researcher.
