The NEMO collaboration is presently mounting the NEMO3 detector in the Fréjus Underground Laboratory (Laboratoire Souterrain de Modane or LSM). This detector is devoted to search of neutrinoless double beta decay of various isotopes and especially Molybdenium 100. It will be able to reach a sensitivity to neutrino effective mass in the order of 0.1 eV. The NEMO3 detector is composed of 20 sectors. Three of them take data in Modane since the end of April, without shielding or magnetic field. The full detector is planned to be in operation by the end of the year.
