Accelerator Driven System (ADS) subcritical reactors are being developed around the world, to produce energy and, at the same time, to provide an efficient way to dispose of and to recycle nuclear waste. Spent nuclear fuel, by itself, cannot sustain a chain reaction; however, in ADS reactors the additional neutrons required to sustain the reaction will be supplied by a high-intensity accelerator. In China the C-ADS collaboration is working on the research and development of such an accelerator, starting with a low-energy beam and increasing the energy up to 1.5 GeV. In the first phase of the project, characterized by low beam energy, it will be possible to produce electron antineutrinos via Isotope Decay At Rest (IsoDAR), which can be used to provide competitive bounds on sterile neutrinos in the disappearance channel. Later, when the beam energy will rump up to its nominal value, the accelerator activity will produce, as a by-product, a large quantity of muon antineutrinos via muon Decay At Rest (muDAR). Using liquid scintillator detectors, it will be possible to exploit them to measure the CP-violating phase delta_CP and to look for experimental signs of the presence of sterile neutrinos in the appearance channel, testing the LSND and MiniBooNE anomalies.
