Data testing has been performed for U-233 fast and thermal benchmarks. Results are presented for both ENDF/B-VI and a modified JENDL-3.2 evaluation. The revised JENDL-3.2 evaluation is summarized and comparisons with ENDF/B-VI and measured values are discussed. Calculated results using both cross section sets are presented for 10 fast benchmarks (reflected and unreflected U-233 metal) and 38 thermal benchmarks (uranyl-nitrate solutions in spherical and cylindrical geometry). Using the revised JENDL-3.2 evaluation, very good results are obtained for the calculated k-effs for almost all of the 48 benchmarks considered in this study. Possible future work is discussed briefly.
