Production of Multigroup Data Covariance in the Resonance Range by Monte-Carlo Calculations
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.
