Nuclear data correlation between different isotopes via integral information
Abstract
This paper presents a Bayesian approach based on integral experiments to create correlations between different isotopes which do not appear with differential data. A simple Bayesian set of equations is presented with random nuclear data, similarly to the usual methods applied with differential data. As a consequence, updated nuclear data (cross sections, $\bar \nu$, fission neutron spectra and covariance matrices) are obtained, leading to better integral results. An example for $^{235}$U and $^{238}$U is proposed taking into account the Bigten criticality benchmark.
