Sensitivity of the analysis of heterogeneous core critical assemblies to cell modelling
Description
The ZPPR-7 Phase A critical experiments have been analyzed using multigroup cross sections generated for several different cell models of the drawers and self-shielding approximations. Single drawer models and four-drawer models consisting of fuel and blanket regions are considered. The cross sections are self-shielded using both a ''multi-region equivalence relation'' and a ''two-region equivalence relation.'' Provided the multigroup constants are properly self-shielded, criticality and the reaction rates are only slightly sensitive to the cell modelling
