    The MCNP program and the ENDF/B-VII.1, ENDF/B-VIII.0 nuclear data were used to calculate the criticality respect to the critical benchmarking suits of 119 models for nuclear data testing. The benchmarking suits consists of 233U, high-enriched uranium, intermediate enriched uranium, low-enriched uranium and Pu critical configurations in fuel type, covering the spectra of fast, intermediate, and thermal neutrons. With ENDF/B-VIII.0 nuclear data, the average and standard deviation of the relative deviation between the calculation keff and the benchmarking keff were -68.98×10-5 and 407.88×10-5 respectively, and the tallies that the ratio of deviation to experimental uncertainty within 1σ, among 1σ–3σ and beyond 3σ were 107, 9 and 3, respectively. The resultant data were compared to the calculation results with ENDF/B-VII. 1 in the same computation conditions, which indicates that the ENDF/B-VIII.0 nuclear data was more accurate, and more consistent with the benchmarking results for criticality calculation.
