Two of the main problems that neutrino experiments will try to solve in the next decade are the determination of the mass hierarchy and the measurement of the (eventual) CP violation in the leptonic sector. INFN is part of the JUNO collaboration: this reactor neutrino experiment, located in China, will attempt to answer to the first question; its scientific program will also include the precise measurement of the mixing parameters, in particular theta_12 and DeltaM^2_12. However, since only the survival probability will be able to measured, it will not be possible to determine delta_CP. I will give an overview of this kind of experiment, discussing the precision that be achieved and the challenges that will be faced, like the rejection of the background due to cosmogenic muons and the possible problems related to systematic errors in the energy calibration. I will also discuss briefly the possibility offered to the Accelerator Driven Subcritical Reactors (ADS). Here spent nuclear fuel will be used to substain a nuclear power plant. The additional neutrons needed for the chain reaction will be provided by a accelerator, where a proton beam hits a spallation target. This will produce, as a by-product, a large amount of muon antineutrinos; using liquid scintillators it will be possible to study the disappearance probability and to measure delta_CP.
