    Summary
    Abstract.: This work presents a novel approach to improve neutronics simulations, as in the case of criticality calculations, by simply combining the results of a limited set of random evaluations. Another outcome of this work is to lower uncertainties due to nuclear data by integrating the information from criticality benchmarks into the neutronics simulations scheme. Examples are presented for the 239Pu nuclear data and calculations of criticality benchmarks and a MOX fuel pincell.
