RENO (Reactor Experiment for Neutrino Oscillations) is a short baseline reactor
neutrino oscillation experiment in
South Korea. The experiment was designed to either measure or set a limit on the
neutrino mixing matrix parameter
θ13, a parameter responsible for oscillations of
electron neutrinos into other neutrino flavours. RENO has two identical detectors, placed at distances of 294 m and 1383 m, that observe electron antineutrinos produced by six reactors at the
Hanbit Nuclear Power Plant (the old name: the Yeonggwang Nuclear Power Plant) in Korea.
