    Neutrino oscillations are the only experimentally observed phenomenon that does not fit within the standard model of the electro-weak interaction. Due to the characteristics of neutrinos, experiments are sensitive only to the squared mass difference (Δm2) of the neutrino states and to the mixing angles (θ). Using improved predictions of reactor antineutrino spectra, the experimental limits on neutrino oscillation parameters are recalculated for an old experiment where the data was taken from 2 nuclear reactors located at Krasnoyarsk. These corrections provide us more information regarding the behavior of neutrinos and the allowed regions where a fourth non-standard neutrino could exist. A computational analysis is made, and the results are represented as exclusion plots for the oscillation parameters.
