We are interested in neutrinos emitted by reactors in a region of keV, since they may have information on fuel burn-up and may be detected in future with advanced measurement technology. In this work we present neutrino spectra from various reactors such as typical PWR reactor and others types of reactors for comparison in the low energy region. Our result shows the electron antineutrino flux in the low energy region increases with burn-up of nuclear fuel by accumulated nuclides with low Q values in beta decay.
