* Title: Status and Prospects of RENO

* Abstract: RENO is a reactor neutrino experiment located in Yonggwang, Korea consisting of two identical detectors in near and far sites. In 2012 using 220 live days of data RENO measured the last unknown mixing angle theta_13 with 4.9 sigma from the deficit of the neutrinos in the far detector. The relatively large value of theta_13 allows searching for leptonic CP violation and neutrino mass ordering.

In 2015 using 500 live days of data RENO updated theta_13 and obtained first measurement on |dm^2_ee|. And they are sin^2 (2theta_13) = 0.082 +- 0.009(stat.) +- 0.006 (syst.) and |dm^2_ee| = 2.62 +0.21 -0.23 (stat.) +0.12 -0.13(syst.) (X 10^-3) eV^2. The systematic uncertainty of sin^2(2q13) has improved mainly due to the better estimation of the Li9/He8 background and the reduction of its uncertainty.

In this lecture I will introduce RENO experiment, its status and future prospects.
