[en] The role of the ENEA-NUCLECO in the management of radioactive waste in Italy is described. In particular the different tasks of the two companies are emphasized. ENEA is mainly involved in the establishment of acceptance criteria, definition of strategies for the management of radwaste, research development, selection, acquisition and qualification of final repositories. NUCLECO, on its own, provides treatment, conditioning and temporary storage of all the wastes produced in Italy and transports them to Casaccia Center, near Rome. Several types of waste are treated by NUCLECO: LLW and MLW arising from medical, research and industrial activities; dry active waste (DAW); large dimension contaminated equipments from decommissioning operations; wastes from nuclear power plants. Different technologies are used for the treatment of such wastes: supercompaction, treatment ofliquid wastes, cementation. The NUCLECO's experiences in the area of spent fuel and in decommissioning of research reactors and laboratories are also described
