Abstract
This paper examines the sensitivity of the MONK criticality code to a variety of nuclear data parameters. The number of equiprobable bins for both secondary energies and secondary angles are varied; the effect of varying the background cross section employed by the sub-group representation in the unresolved region is examined; and variations in cross section resonance reconstruction tolerances are considered. To validate these options we use integral data including results from the GODIVA, JEZEBEL and ZEBRA-8H experiments. The results from this study will be used to optimise data used in the MONK criticality code.
