Neutrino oscillations at nuclear reactors

The status and the prospects of neutrino oscillation at nuclear reactors is reviewed. Neutrino oscillations are the best tool for probing neutrino mass and lepton number non-conservation. Five neutrino oscillation experiments have been carried out since 1981 but did not show any evidence for oscillations. New experiments are prepared by the Bugey group, the Moscow group and the Rovno group. New generations of detectors should play a role to fill the gap betwen present reactor limits and solar neutrino limits
