In France, graphite was used as neutron moderator as well as structure material for the design of the first reactors called UNGG (Natural Uranium Graphite Gas-cooled Reactors). Such a concept of reactors was given up in 1969 in favor of water pressurized reactors using enriched uranium. In the following years (-1992) the nine UNGG were shut down. Then, the question of the dismantling of such reactors arose and of course those of the irradiated graphite. Numerous studies were thus launched in order to investigate different ways for the management of the irradiated graphite from direct storage to thermal or chemical treatments. The aim of this study consists in setting up a Raman spectroscopy equipment in a hot cell in order to perform invest...
