Exploded view of a Double Chooz detector

Neutrinos are quite remarkable elementary particles which are produced in great abundance in the sun, in the atmosphere and at the core of nuclear power reactors. DAPNIA has been interested in them for a very long time. It has now been established that although they are very light, neutrinos do not have zero mass. It remains to be determined how these masses are distributed among the three known varieties of neutrino: ne, nμ and nτ

Based on recent progress in experiments, it seems that these neutrinos could provide remote information about the fuel used in nuclear reactor cores.
