An ENDF/B Decay Data Sub-library Reactor Antineutrino Spectra Comparison to Recently Measured Decay Product Spectra.

Nuclear databases continue to play an important role in understanding electron antineutrino production in nuclear reactors, which is important for refining our understanding of neutrino oscillations, reactor monitoring, and non-proliferation. Here the current up to date ENDF/B decay data sublibrary is utilized to construct the reactor antineutrino summation spectra for all relevant power reactor fuels in order to compare these spectra to experimentally measured fission decay product electron spectra results. This effort highlights the need for continued studies in fission decay product electron spectra. Likewise, trends are revealed when the ratio of these summation spectra are taken against the Huber-Mueller spectra.
