The RENO experiment reports measured flux and energy spectrum of reactor electron antineutrinos,($overline{ u}_e$) from the six reactors at Hanbit Nuclear Power Plant. The measurements use 966,094,(116,111),$overline{ u}_e$ candidate events with a background fraction of 2.39%,(5.13%), acquired in the near,(far) detector, from August 2011 to March 2020. The inverse beta decay (IBD) yield is measured as (5.852$,pm,$0.124$) times 10^{-43}$,cm$^2$/fission, corresponding to 0.941,$pm$ 0.019 of the prediction by the Huber and Mueller (HM) model. A reactor $overline{ u}_e$ spectrum is obtained by unfolding a measured IBD prompt spectrum. The obtained neutrino spectrum shows a clear excess around 6,MeV relative to the HM prediction. The obtained reactor $overline{ u}_e$ spectrum will be useful for understanding unknown neutrino properties and reactor models. The observed discrepancies suggest the next round of precision measurements and modification of the current reactor $overline{ u}_e$ models.
The RENO experiment reports more precisely measured values of $theta_{13}$ and $|Delta m_{ee}^2|$ using $sim$2,200 live days of data. The amplitude and frequency of reactor electron antineutrino ($overline{ u}_e$) oscillation are measured by comparin
This Letter reports a measurement of the flux and energy spectrum of electron antineutrinos from six 2.9~GW$_{th}$ nuclear reactors with six detectors deployed in two near (effective baselines 512~m and 561~m) and one far (1,579~m) underground experi
A new measurement of the reactor antineutrino flux and energy spectrum by the Daya Bay reactor neutrino experiment is reported. The antineutrinos were generated by six 2.9~GW$_{mathrm{th}}$ nuclear reactors and detected by eight antineutrino detector
We report a fuel-dependent reactor electron antineutrino ($overline{ u}_e$) yield using six 2.8 GW$_{text{th}}$ reactors in the Hanbit nuclear power plant complex, Yonggwang, Korea. The analysis uses $850,666$ $overline{ u}_e$ candidate events with a
The Daya Bay experiment has observed correlations between reactor core fuel evolution and changes in the reactor antineutrino flux and energy spectrum. Four antineutrino detectors in two experimental halls were used to identify 2.2 million inverse be
