Perturbation analysis of cross-section differences between the ENDF/B-III file and the KEDAK file helped identify those differences to which keff of large fast systems was sensitive. The interpretation of differences between independently evaluated files as inherent inaccuracies in current experimental data led to recommended requirements for experimental accuracy in 239Pu and 238U fission and capture cross sections.
