In order to compare the ENDF/B-VIII.0 and CENDL-3.2 Fe-56 nuclear data, twenty-nine iron sensitive models were selected from the International Criticality Safety Benchmarking Experiments Evaluation Project(ICSBEP), including twenty-one highly enriched uranium models and eight plutonium metal models.The benchmark models were modeled in MC program and keff were calculated with complete ENDF/B-VIII.0, and with hybrid ENDF/B-VIII.0 with CENDL-3.2 Fe-56 substituted, respectively. For most models, the benchmarking criticality calculation results show that with hybrid ENDF/B-VIII.0 there are 381 pcm or less reduction in keff, compared with complete ENDF/B-VIII.0. Besides, it shows improved agreement for plutonium metal models and a little worsened agreement for highly enriched uranium models with hybrid ENDF/B-VIII.0.
