The RENO(Reactor Experiment for Neutrino Oscillation) experiment is to measure the smallest neutrino mixing angle theta13 and |dm^2_ee| using anti-neutrinos emitted from the Hanbit nuclear power plant in korea. Due to unprecedentedly copious data and an accurate energy calibration, the experiment has measured the flux and energy spectrum of reactor electron antineutrinos quite precisely. It is essential to compare the observed and expected fluxes of reactor antineutrinos for determining the neutrino disappearance. The reactor neutrino flux is calculated from the reactor thermal power and the fission rate of individual fuel isotope. Time-dependent fuel composition changes the antineutrino fluxes and spectrum. We have observed an excess near 5 MeV with respect to the most commonly used reactor neutrino models. In this presentation, we describe how to derive the expected reactor neutrino fluxes and spectrum at both near and far detectors and present the comparison between data and prediction.
