  We review the status and the results of reactor neutrino experiments, that
toe the cutting edge of neutrino research. Short baseline experiments have
provided the measurement of the reactor neutrino spectrum, and are still
searching for important phenomena such as the neutrino magnetic moment. They
could open the door to the measurement of coherent neutrino scattering in a
near future. Middle and long baseline oscillation experiments at Chooz and
KamLAND have played a relevant role in neutrino oscillation physics in the last
years. It is now widely accepted that a new middle baseline disappearance
reactor neutrino experiment with multiple detectors could provide a clean
measurement of the last undetermined neutrino mixing angle theta13. We conclude
by opening on possible use of neutrinos for Society: NonProliferation of
Nuclear materials and Geophysics.
