초록:  RENO is a reactor based neutrino oscillation experiment to measure the neutrino mixing angle q13 using anti-neutrinos emitted from the Yonggwang nuclear power plant in Korea. Its thermal power output is 16.4 Gwth. The experimental setup consists of two identical 16-ton Gadolinium loaded liquid scintillator detector located near and far from the reactor array to measure the deviations from the inverse square distance law. The near and far detectors are to be placed roughly 290 m and 1.4 km from the center of the reactor array, respectively. The near detector was constructed at underground of a 70 m high hill and the far detector at underground of a 260 m high mountain. The construction of experimental halls and access tunnels for both near and far detector sites was completed in early 2009. The experiment is planned to start data-taking in early summer 2011. An expected number of observed anti-neutrino is roughly 510 and 80 per day in the near detector and far detector, respectively. Based on three years of data, it would be sensitive to measure the neutrino mixing angle in the range of sin2(q13) > 0.02. This sensitivity is ten times better than the current limit obtained by CHOOZ.  In this talk, all details for RENO experiment will be reviewed.
