Abstract: The generation of Multi-group cross sections together with relevant uncertainties is fundamental to assess the quality of neutronic simulations. Key information that are needed to propagate the microscopic experimental uncertainties up to macroscopic reactor calculations are (1) the experimental covariance matrices, (2) the correlations between the parameters of the model and (3) the multi-group covariance matrices. This work proposes to apply a Monte-Carlo approach to provide explicit data covariances between the resonance parameters.
