Abstract

The Reactor Experiment for Neutrino Oscillation (RENO) started data-taking since August, 2011 and has successfully measured the smallest neutrino mixing angle θ13 in 2012 using 220 days of data by observing the disappearance of reactor antineutrinos. Antineutrinos from the six reactors at Hanbit Nuclear Power Plant in Korea are detected and compared by the two identical detectors located at the near and far distances from the reactor array center. In 2016, RENO has published an updated value of θ13 and its first measurement of |∆m2ee| based on energy dependent disappearance probability using 500 days of data. In this talk, we present precise measurement of θ13 and |∆m2ee| using more data and improved systematic uncertainties. In addition, the 5 MeV excess of reactor antineutrino spectrum will be reported.
