Monte Carlo Analysis of Aqueous ²³⁵U Critical Assemblies with ENDF/B-V Data

Ten aqueous homogeneous critical assemblies were analyzed with ENDF/B-V data by means of the SAM-CE continuous energy Monte Carlo code. Calculated k_eff values are consistent with experiment for large, dilute assemblies but become systematically as much as 1% too large for assemblies with both high leakage and hard flux spectra. Adjustments of k_eff to measured capture and fission integrals indicate improvements that should be investigated further.
