Abstract. This paper briefly describes recent progress of RENO and next generation future prospect of the reactor neutrino oscillation experiment, RENO-50. Recently the RENO experiment has updated its latest value on sin 2 2θ 13 and provided new results on 5 MeV excess, m 2 ee , θ 13 with n-H analysis, absolute antineutrino flux measurement, and sterile neutrino search. It gives rich programs of neutrino properties, detector development, nuclear monitoring and application. Using reactor neutrinos, the future RENO-50 experiment will search for more precise measurement of θ 12 , Δm 2 12 and mass hierarchy.

“…Existence of neutrino mass requires modification of the Standard Model and provides hints on the Grand Unification Theory. The smallest neutrino mixing angle θ 13 in the PMNS matrix [5,6] is definitively measured in 2012 by Daya Bay [3] and RENO [4]. The leptonic CP phase δ CP and neutrino mass ordering are now possible to be measured due to the large value of θ 13 .…”

The Reactor Experiment for Neutrino Oscillation (RENO) has been taking electron antineutrino (ν e ) data from the reactors in Yonggwang, Korea, using two identical detectors since August 2011. Using roughly 500 live days of data through January 2013 we observe 290 775 (31 514) reactorν e candidate events with 2.8% (4.9%) background in the near (far) detector. The observed visible positron spectra from the reactorν e events in both detectors show a discrepancy around 5 MeV with regard to the prediction from the current reactorν e model. Based on a far-to-near ratio measurement using the spectral and rate information, we have obtained sin 2 2θ 13 ¼ 0.082 AE 0.009ðstat:Þ AE 0.006ðsyst:Þ and jΔm

“…Each RENO detector consists of a main inner detector (ID) and an outer veto detector (OD). The ID is contained in a cylindrical stainless steel vessel that houses two nested cylindrical acrylic vessels [10]. The innermost acrylic vessel holds 16.5 tons of Gd-doped LS as a neutrino target, and is surrounded by a γ-catcher region with arXiv:1806.00248v3 [hep-ex] 13 Sep 2018 a 60 cm thick layer of undoped LS inside an outer acrylic vessel.…”

The RENO experiment reports more precisely measured values of θ13 and |∆m 2 ee | using ∼2 200 live days of data. The amplitude and frequency of reactor electron antineutrino (νe) oscillation are measured by comparing the prompt signal spectra obtained from two identical near and far detectors. In the period between August 2011 and February 2018, the far (near) detector observed 103 212 (850 666) νe candidate events with a background fraction of 4.8% (2.0%). A clear energy and baseline dependent disappearance of reactor νe is observed in the deficit of the measured number of νe. Based on the measured far-to-near ratio of prompt spectra, we obtain sin 2 2θ13 = 0.0896 ± 0.0048(stat) ± 0.0047(syst) and |∆m 2 ee | = [2.68 ± 0.12(stat) ± 0.07(syst)] × 10 −3 eV 2 .
